Wire Mesh Belt Shot Blasting Machine QWD | Mn13 Belt

The QWD series wire mesh belt shot blasting machine carries workpieces flat on a woven Mn13 belt through an enclosed blast chamber. Opposed blast wheels throw abrasive at 60-80 m/s. One pass strips oxide scale, rust, moulding sand, welding slag and burrs. It reaches Sa 2.5 per ISO 8501-1.

Parts never tumble and never strike one another. That makes this the standard machine for fragile, threaded and cosmetically critical work. Typical parts are aluminium die castings, brake discs, thin-wall housings, fasteners, heat-treated components and precision machined parts.

1. What is a wire mesh belt shot blasting machine?

A mesh belt shot blasting machine is a continuous pass-through blast machine. Workpieces lie flat in a single layer on an endless woven metal belt. The belt carries them into a sealed chamber. Blast wheels mounted above and below strike both faces at the same time. Cleaned parts exit at the far end while loading continues at the near end. The machine never stops for a batch change.

This is a through-feed or pass-through process. European catalogues call it a continuous flow machine. North American buyers call it a continuous pass-through blast machine. German catalogues list it as a wire belt blast machine. It is one machine under four names.

The defining feature is that parts stay exactly where they were loaded. There is no tumbling, no part-to-part impact and no re-fixturing. Abrasive falls straight through the open mesh. The underside is therefore cleaned in the same pass as the top face.

2. What do overseas buyers call this machine?

Buyers search by the name they already know. This page therefore covers every wording in use. The two most valuable entries are listed first. They are the global long form, and the short official form used by two European and American manufacturers.

Term	Where it is used
wire mesh belt shot blasting machine	Global standard term, used by Rosler, Gostol TST, GEC Blasting, OMSG and Acton Finishing
wire mesh belt blast machine	Official short form on the Rosler RDGE and Pangborn product pages, with no shot in the name
wire mesh belt conveyor shot blasting machine	DirectIndustry listing for the Gostol KTP type, and Chinese export catalogues
wire mesh shot blasting machine	Short form common on European and Indian supplier sites
mesh belt shot blasting machine	Dominant wording on Made-in-China, Alibaba and GoldSupplier listings
wire belt blast machine	German catalogue wording
continuous feed blast machine / pass through shot blasting machine	Buyers searching by process type rather than by belt design
double sided shot blasting machine	Buyers searching by the both-faces-in-one-pass capability
QWD series	Our model prefix for this machine class, for example QWD1200
RDGE (Rosler), KTP (Gostol TST), CWB (OMSG), LBS (Wheelabrator), RSAB (Rosler)	Reference model series buyers name when asking for a comparable machine

Model codes buyers search

Three coding systems appear in enquiries for this machine class. QWD is the Chinese model prefix, where the number is the effective belt width, so QWD1200 carries a 1000 mm effective belt inside a 1200 mm chamber opening. RDGE is the Rosler designation. KTP is Gostol TST, CWB is OMSG and LBS is the Wheelabrator mesh belt series. All describe the same continuous flat-belt arrangement.

If you send us a competitor model code, we return a like-for-like configuration against it. We do not send a generic catalogue machine.

3. Why does the Mn13 Mn13 belt matter?

Mn13 is the Chinese designation for a high manganese austenitic wear steel, standardised as ZGMn13 under GB/T 5680. Its defining property is work hardening. As-supplied hardness is about HB 200-250. Under repeated impact from abrasive and workpieces, the surface layer hardens to HB 500 and above. The core stays tough and absorbs shock.

Two consequences matter to a buyer. First, the harder the impact, the more wear resistant the surface becomes. The material therefore suits the high-pressure, high-impact duty inside a blast chamber better than almost any alternative. Second, as the hardened layer wears away, fresh metal is exposed. It hardens again in its place. A liner is therefore consumed through its full thickness instead of failing at the surface.

Standard	Equivalent designation	Where buyers recognise it
China GB/T 5680	Mn13 / ZGMn13	Asia, Middle East, Africa, South America
USA ASTM A128	Hadfield Mn13	North America
Europe EN	X120Mn12, material number 1.3401	Germany and the EU
Trade name	Mn13	All markets

Buyers in North America search this material as Hadfield Mn13. A Hadfield Mn13 belt blast machine is exactly that material class. European buyers search the same steel as X120Mn12. It is one material under three designations.

Why the belt needs water toughening and a run-in period

Mn13 is water toughened before machining. This puts the austenite in the soft, tough condition that later work hardens. After roughly 40-80 running hours the hardened surface layer fully develops. Wear resistance then rises sharply. That run-in period is normal behaviour for this steel, not a defect. Slight early belt wear during commissioning is expected. It should not be read as a manufacturing fault.

4. How does a QWD mesh belt shot blasting machine work?

Workpieces are loaded on the infeed section of the belt and travel at an inverter controlled speed of 0.5-3 m/min. Four to eight blast wheels strike the parts in a single pass. The wheels sit in opposed pairs above and below the belt, angled at about 45 degrees. Flat faces, side faces and shallow cavities are therefore covered together.

Spent abrasive falls through the mesh openings into the chamber floor. Screw conveyors carry it to a bucket elevator. The elevator lifts it to a full flow air wash separator. The separator removes dust, fines and fractured media at a controlled air velocity of 4-5 m/s in the separation zone. Only sound abrasive therefore returns to circulation. A dust collector holds the chamber under negative pressure so nothing escapes into the workshop. Cleaned parts then pass a high pressure blow-off station. It clears loose abrasive and dust from the top face before unloading.

Why the full flow separator is the component to check first

The separator decides your running cost more than any other single component. Fractured media that stays in circulation accelerates blade and liner wear without improving cleaning. It also increases abrasive consumption. A full flow air wash separator removes those fines continuously instead of letting them build up. Ask any supplier how their separator works. Ask what air velocity it runs at. A screen-only separator is cheaper to build. It is more expensive to operate.

5. Which QWD model fits my parts?

The model number is the effective belt width. Belt width, wheel count, wheel power, media size and collector capacity all follow from four inputs. These are your part size, loading density, required hourly throughput and target cleaning grade.

The QWD1200 is our documented reference configuration. Its published parameters are shown below. They let you see exactly what one model delivers, rather than reading a range with no anchor point.

QWD1200 parameter	Value
Maximum chamber opening	W 1200 x H 1000 mm
Effective belt width	1000 mm, Mn13 woven mesh
Belt running speed	0.3-2.5 m/min, inverter controlled, 3 kW drive
Cleaning speed	0.5-2 m/min, set to part complexity
Blast wheels	4 units, Q034 type, 4 x 11 kW with inverter
Abrasive throughput	4 x 180 kg/min
Abrasive velocity	72 m/s
Recommended media	0.8-1.2 mm passivated cut wire
Cleanliness achieved	Sa 2.5, Sa 2.0 in local areas, per GB 8923 and ISO 8501-1
Bucket elevator	45 t/h, belt speed 1.22 m/s, 5.5 kW
Air wash separator	45 t/h, separation zone air velocity 4-5 m/s, 3 kW
Screw conveyors	Cross 45 t/h at 3 kW, longitudinal 45 t/h at 5.5 kW
High pressure blow-off	2737 m3/h at 5770 Pa, 7.5 kW, adjustable blow pipe height
Dust collector	Bag type ZMC-96, 96 bags, 18.5 kW fan
Total installed power	about 90 kW, excluding dust collection where separately metered
Power supply	380 V / 50 Hz, control voltage 220 V / 50 Hz
Compressed air	about 1.5 m3/min at 0.6-0.8 MPa, supplied by the customer
Chamber construction	Q235 welded steel, lined with one layer of rolled Mn13 guard plate

Wider belts, more wheels and higher single wheel power are available. Use them for larger parts or heavier scale. Send your part drawing and daily tonnage. We then size the machine from real data instead of quoting a catalogue average.

6. What surface quality does the machine deliver?

Surface property	Result
Cleanliness	Sa 2.5 per ISO 8501-1, equivalent to GB 8923 A-B Sa 2.5 with local Sa 2.0
Higher grades	Sa 3.0 available as an option with more wheel power, finer media and a slower belt
Surface profile	Controlled by media size and dwell time, so batch-to-batch anchor pattern stays repeatable
Residual stress	Impact leaves a compressive surface layer, which raises fatigue strength as well as coating adhesion
Dust emission	below 30 mg/m3 at the collector outlet
Noise	below 85 dB(A) with a double sealed chamber

The noise figure is worth reading against the product standard. JB/T 12557-2015, the Chinese technical conditions for wire mesh belt blast cleaning machines, sets a limit of 93 dB(A). Our double sealed chamber sits below that limit with margin. This matters where the machine runs next to a machining cell or an inspection station rather than in a separate bay.

7. Which parts and industries suit this machine?

A through-feed conveyor shot blasting machine suits flat, thin or shallow parts laid in a single layer. It is strongest where parts are fragile, threaded or cosmetically critical and the volume justifies continuous running.

Industry	Typical workpieces
Automotive and new energy vehicles	Aluminium die cast motor housings, EV battery pack trays, gearbox housings, brake discs and drums, wheel hubs, suspension springs, bearing rings
Die casting and fasteners	Aluminium and zinc castings, stainless pump bodies, screws, bolts, nuts, washers, retaining rings, sintered PM parts, where the flat belt protects thread crests
Heat treatment shops	Gears, sprockets, shafts and forgings after quenching, where scale must come off without marking hardened surfaces
3C electronics and electrical	Aluminium mid-frames, heat sinks, stamped enclosures, motor end caps, radiator and filter profiles
Foundry and forging	Small and medium steel and iron castings for desanding, oxide scale removal and deburring, plus forged hand tools before machining
Medical, food and sanitary hardware	Surgical instrument components, valve bodies, bathroom hardware, railing fittings
Machinery and railway	Hydraulic valve blocks, pump plates, high-speed train interior components
Aluminium formwork	Thin large-area panels, where flat conveying avoids the scratching that hanging or tumbling causes

Which applications drive most enquiries?

Aluminium and zinc die casting plants need a mesh belt shot blasting machine for aluminium die castings, because tumbling rounds off the edges of soft alloy. Brake component makers specify a brake disc shot blasting machine to hold flatness on the friction face. Fastener producers look for a bolt and nut shot blasting machine that cleans threads without flattening the crests.

Foundries running delicate shells ask for a thin-wall casting shot blasting machine. Electronics plants with extruded or die cast heatsinks need a heat sink shot blasting machine that leaves no witness marks on visible faces. Heat treatment shops use the same machine for heat-treated parts finishing after quenching and tempering.

Iron embedding must sometimes be avoided entirely. For that duty a stainless steel wire mesh belt shot blasting machine configuration can be specified at enquiry stage, with non-ferrous media and an isolated abrasive circuit.

8. Why choose a mesh belt over a tumble blast machine?

• Zero part-to-part contact. A tumble blaster collides parts thousands of times per cycle. A continuous mesh belt shot blasting machine holds every part exactly where it was loaded.
• No damage to threads or edges. Bolts, tapped holes and machined sealing faces keep their geometry, so no rework follows the blast stage.
• No thin-wall distortion. The belt supports parts fully across its width instead of lifting and dropping them.
• Both faces in one pass. Abrasive falls through the open mesh, so the underside is cleaned at the same time. No re-fixturing and no manual flipping.
• Genuinely continuous output. Loading and unloading run while the machine blasts, so it links straight into a die casting cell, a machining centre or a painting and coating line.
• Lower maintenance load. There is no tumbling drum, no rubber belt under cyclic folding and no batch door to reseal. This class is therefore often specified as a low maintenance shot blast option.

9. When is a mesh belt machine the wrong choice?

• Parts taller than the chamber opening. On the QWD1200 the opening is 1000 mm high, and we recommend keeping part height to about 400 mm on a standard belt. Above that the load concentrates on too few mesh wires and parts can strike the chamber entry. Choose a hanger type or trolley type machine instead.
• Deep cavities and blind holes. Blasting is a line of sight process, so the stream cannot reach the bottom of a deep cavity. Use a turntable machine or a robotic blast room.
• Very heavy single pieces. The governing limit is load per square metre of belt, not total weight. A dense casting of a given mass behaves very differently from a light panel of the same mass.
• Rugged bulk parts. If the part tolerates impact, a rubber crawler or tilting drum tumble blaster cleans it at lower cost.
• Continuous long stock. Coil, pipe, H-beam and section steel that runs without end belong on a roller conveyor through-feed machine. Discrete plate cut-offs and flat structural components of limited length are exactly what this machine handles, and descaling steel plate cut-offs is the standard duty on the QWD1200.
• Very thin aluminium. Sheet below about 1.2 mm can deform under concentrated impact, even on a flat belt.
• High mix, low volume. This machine is built for continuous running. Intermittent mixed batches suit a hanger or turntable machine better.
• Aluminium or magnesium fines. Non-ferrous processing needs an explosion protected dust collector. Specify it at enquiry stage, because it is a safety item and not a cost option.

10. How do rolled Mn13 liners compare with cast XCr23 liners?

Chamber liners are the second largest consumable after blast wheel blades. The two common choices behave very differently under abrasive impact. The difference is measurable rather than a matter of opinion.

Property	rolled Mn13	cast XCr23 steel
Surface hardness as supplied	HRC 60 or above	HRC 55 or above
Surface hardness after blast impact	HRC 85 or above, work hardens further	HRC 55 or above, does not harden further
Porosity	none, one-piece rolled plate	Present, an inherent casting characteristic
Density	7.95 g/cm3	About 7.75 g/cm3
Liner life around the blast outlet	4500 hours or more	About 1500 hours
Liner life elsewhere in the chamber	9000 hours or more	About 3000 hours
Can it be cut, welded and repaired	yes	No

Two mechanisms explain the gap. A cast liner contains micro porosity, and a single small pore gives the abrasive a starting point to break through the surface. A rolled plate has none. Its higher density also means fewer internal defects, so deformation under impact is uniform and hardening happens faster. Rolled Mn13 also keeps forming a fresh hardened layer as the previous one wears. A 12 mm plate is therefore used through its full thickness.

These are material-level comparison figures for the two liner classes. They are not a guarantee for one specific duty. Actual liner life depends on abrasive type, wheel power, running hours and part mix. On this machine the liners last about three times longer than ordinary steel plate in equivalent duty.

11. Which blast wheels, media and dust collection are used?

• Blast wheels – normally 4 to 8 units of 7.5-22 kW each, opposed above and below the belt for double-side coverage, impeller diameter 360-420 mm. Wheels are dynamically balanced before assembly.
• Abrasive – steel shot S330-S550 for general work, media diameter 0.5-1.5 mm. The QWD1200 reference build uses 0.8-1.2 mm passivated cut wire. For aluminium and non-ferrous alloys use stainless shot or dedicated aluminium media.
• Heavy parts with thick scale – increase wheel count or single wheel power rather than slowing the belt. Throughput is then not sacrificed.
• Abrasive recovery – bucket elevator at 45 t/h on the QWD1200, plus a full flow air wash separator at 4-5 m/s in the separation zone.
• Dust collection – cartridge or bag collector under negative pressure, emission below 30 mg/m3. Specify an explosion protected collector for aluminium and magnesium fines.
• Control system – PLC with touch screen, manual and automatic modes, fault alarm, and inverter control on both belt drive and blast wheels.
• Line integration – infeed and outfeed conveyors, part presence sensors, blow-off station, load and unload robots and PLC data output.

12. How do you start and stop the machine safely?

Start and stop sequence causes more abrasive spillage and belt jamming than anything else on through-feed machines. The correct order is fixed. It belongs in the operator instruction.

Stage	Correct sequence
Start-up	Dust collector, then separator, then bucket elevator, then screw conveyors, then belt conveyor, then blast wheels. Only after the wheels are running should the abrasive gates open.
Running	Load parts on the infeed belt. Open the abrasive gates when parts reach the set position. The blow-off station clears loose abrasive as parts leave the chamber.
Shutdown	Close abrasive gates first, then blast wheels, then screw conveyors, then bucket elevator, then separator, then dust collector, then belt. The belt stops last.

Two rules carry most of the weight. Never open the abrasive gates before the wheels are at speed, and never stop the recovery circuit before the wheels. Reversing either leaves abrasive standing in the chamber or in the elevator boot. The next start then jams under load.

13. How do you keep the machine running?

Interval	Maintenance action
Every shift	Check blast wheel running sound, belt tension and tracking, and dust collector pressure differential
Weekly	Grease blast wheel bearings, elevator shaft and gearbox. Inspect rubber curtains and door seals
Monthly	Inspect blades, control cages and liners for wear. Replace parts past the limit
Quarterly	Clean or replace dust collector elements. Clean and retighten electrical panels
Annually	Full strip-down inspection. Replace worn screws and elevator belts

Belt tension is the most common cause of unplanned stoppage on this machine class. Check it every shift. A slack belt tracks sideways and wears at the edges long before the mesh itself fails. Edge wear is what puts the belt out of service, not wear across the load area.

Costs and quotation

On manufacturing standard, blast wheel service life and surface finish consistency, the comparison is fair. Cost and lead time depend on the line configuration and project requirements.

Factor	Dingtian provision	Notes
Wear part lead time	days, not weeks	No import routing and no OEM allocation queue
Abrasive consumption	lower	Full flow air wash separator removes fractured media before it recirculates
Local service	open part numbers	Motors, gearboxes, bearings, PLC, inverters and collector elements use common international specifications, so your own maintenance team can service them

Quality is not where the cost was cut. Mn13 liners, XCr23 alloy blades, sealed bearing housings and full length curtains are standard, not optional. Every machine is run tested and blast tested before shipment. An ISO 8501-1 cleanliness report on your sample parts is available on request.

As an OEM ODM shot blasting machine manufacturer and source factory, we build to your drawing. We do not build to a fixed catalogue. Reference designs buyers ask us about include the Wheelabrator LBS mesh belt series, the Pangborn wire mesh belt blast machine, the Rosler RDGE and the Gostol KTP type.

15. What are the commercial and delivery terms?

Term	Value
Delivery lead time	30 to 120 days, depending on configuration and order scope
Port of loading	Shanghai, China, UN/LOCODE CNSHA
Price basis	Quoted per configuration once the four sizing parameters are confirmed
Customisation	OEM and ODM, built to customer drawing
After-sales support	Installation manual, video guidance, remote online support, spare parts supply
Pre-shipment testing	Run test and blast test; ISO 8501-1 cleanliness report on customer samples on request

Lead time depends on belt width and wheel count. It also depends on whether an explosion protected dust collector or an isolated non-ferrous abrasive circuit is included. A standard QWD configuration ships at the short end of the range. A fully integrated build with load and unload robots, infeed and outfeed conveyors and PLC data output takes longer. We confirm the delivery date in writing at quotation stage.

Shipments leave from Shanghai (CNSHA). If your forwarder prefers another Chinese port, tell us at order stage and we arrange inland transport to suit.

16. Frequently asked questions

What is the difference between a mesh belt and a tumble shot blasting machine?

A tumble cleaner rotates parts against one another, so it leaves impact marks. It suits rugged bulk parts where cosmetics do not matter. A mesh belt cleaner conveys parts flat and still. It cleans top and bottom at the same time, with zero part-to-part contact. It suits fragile, precision, threaded or thin-wall parts. If a part cannot tolerate a single dent, choose the mesh belt machine.

What is Mn13 steel, and is it the same as Hadfield Mn13?

Mn13 is the Chinese GB/T 5680 designation for a high manganese austenitic wear steel. It is written ZGMn13. It corresponds to ASTM A128 in the USA, where it is called Hadfield Mn13. In Europe it is X120Mn12, material number 1.3401. All three are the same work hardening class. Its value here is work hardening. The surface hardens from about HB 200-250 to HB 500 and above under abrasive impact, while the core stays tough. The belt and liners therefore resist wear instead of stretching or cracking.

How does the Mn13 Mn13 belt perform in daily industrial use?

The belt is woven from high quality Mn13 Mn13, which is highly wear resistant. It takes heavy loads and elevated temperature duty. It also work hardens in service, from about HB 200-250 as supplied to HB 500 and above under abrasive impact. As the hardened layer wears, fresh metal hardens in its place. The belt is therefore consumed through its full thickness instead of failing at the surface. That is what extends service life well beyond ordinary steel belt and liner materials.

What is the difference between a wire mesh belt shot blasting machine and a wire mesh belt blast machine?

Nothing, they are the same machine. Rosler and Pangborn both use the shorter form wire mesh belt blast machine on their product pages. Most other suppliers and B2B platforms write wire mesh belt shot blasting machine. The belt design and the through-feed process are identical. Both terms describe a continuous machine that carries parts flat on a woven metal belt past opposed blast wheels.

What does the QWD model number mean?

QWD is our model prefix for wire mesh belt through-feed blast cleaning machines. The number is the chamber opening width. A QWD1200 has a maximum chamber opening of W 1200 x H 1000 mm. Its effective belt width is 1000 mm, with four Q034 blast wheels of 11 kW each. Abrasive velocity is 72 m/s and total installed power is about 90 kW. Other manufacturers use RDGE, KTP, CWB and LBS for the same machine class.

Is this machine built to a recognised product standard?

Yes. It is built against JB/T 12557-2015. That standard sets the technical conditions for wire mesh belt blast cleaning machines, including a noise limit of 93 dB(A). Our double sealed chamber runs below 85 dB(A). Surface cleanliness is reported to ISO 8501-1 and GB 8923. Both use the Sa grading scale. A Sa 2.5 result therefore means the same thing to a buyer in any market.

What kind of workpieces are suitable for this machine?

It is designed for large but relatively thin and flat parts. These include steel plate cut-offs, flat structural components and wire mesh products. Aluminium die castings, brake discs, thin-wall housings, fasteners and heat sinks are equally suited. The governing rule is that the part lies flat in a single layer and stays inside the chamber opening. Standard duty on the QWD1200 is descaling and derusting steel plate cut-offs.

What surface cleanliness and profile can it achieve?

Sa 2.5 per ISO 8501-1 is the standard acceptance result, with local Sa 2.0 in sheltered areas. Sa 3.0 is available as an option. It needs more wheel power, finer media and a slower belt. Surface profile is controlled by media size and dwell time. A repeatable anchor pattern therefore keeps batch to batch consistency for painting or powder coating.

Can this machine blast aluminium and magnesium die castings?

Yes, it is one of the most common applications. Use non-ferrous media such as stainless shot, cut wire or dedicated aluminium media. Keep the abrasive circuit isolated or thoroughly cleaned. Iron must not embed, because embedded iron causes corrosion staining later. Reduce belt speed and wheel power compared with steel work. Soft alloy edges then do not round off. Fit an explosion protected dust collector for aluminium fines.

What is the maximum part size and weight?

Belt width runs from 600 mm to over 2000 mm on custom models. The QWD1200 chamber opening is W 1200 x H 1000 mm. We recommend keeping part height to about 400 mm on a standard belt. The governing limit is load per square metre of belt rather than total weight. A light part spread over a large area behaves very differently from a dense casting of the same mass. Send a drawing and we confirm the belt rating for your parts.

Can I customize the wire mesh belt shot blasting machine according to my workshop size?

Yes, we provide customised machines. Belt width is adjustable from 600 mm to over 2000 mm, so the machine fits your workshop footprint and your cleaning requirement. Wheel count, wheel power, media specification, chamber height, dust collection and infeed and outfeed conveyors are all configured to your drawing. Send your layout and part data. We then return a tailored configuration rather than a catalogue machine.

How fast is the belt, and can the speed be changed?

Belt speed runs from 0.5 to 3 m/min under inverter control. The QWD1200 belt drive itself covers 0.3 to 2.5 m/min. Slower speed means longer dwell time. It gives heavier scale removal and a coarser profile. Faster speed means higher throughput on light cleaning duty. The operator sets it from the touch screen for each part family.

Why do rolled Mn13 liners outlast cast XCr23 liners?

cast XCr23 liners contain micro porosity. Abrasive breaks through at a pore. Rolled Mn13 plate has none. Its density of 7.95 g/cm3, against about 7.75 g/cm3, also means fewer internal defects and more uniform hardening under impact. Rolled Mn13 also hardens further in service, from HRC 60 or above to HRC 85 or above. It forms a fresh hardened layer as the previous one wears. Reference service figures are 4500 hours or more around the blast outlet, against about 1500 hours for cast XCr23. Elsewhere in the chamber the figures are 9000 hours or more against about 3000 hours. Rolled plate can also be cut, welded and repaired. Cast liners cannot.

Are spare parts expensive or slow to supply?

Contact us for a quotation based on the machine configuration, production capacity, and project requirements.

Can it run on an automated production line?

Yes, this is its main structural advantage. Infeed and outfeed conveyors, part detection sensors, blow-off stations, load and unload robots and PLC communication are all available. They let the blaster run as one station inside a die casting cell, a machining line, or a pretreatment line ahead of painting, powder coating, plating or bonding.

What is the correct start and stop sequence?

Start with the dust collector. Then separator, bucket elevator, screw conveyors, belt conveyor and blast wheels. Open the abrasive gates only after the wheels are at speed. Stop in reverse. Close the abrasive gates first, then wheels, screw conveyors, elevator, separator, dust collector and belt last. Reversing either order leaves abrasive standing in the chamber or the elevator boot. The next start then jams.

What is the delivery time, and which port do you ship from?

Delivery lead time is 30 to 120 days, depending on configuration and order scope. A standard QWD machine ships at the short end. A fully integrated build with robots and conveyors takes longer. We confirm the delivery date in writing at quotation stage. Shipments leave from Shanghai, China, UN/LOCODE CNSHA. If your forwarder prefers another Chinese port, tell us at order stage.

Do you provide after-sales support and installation instructions?

Yes. We provide comprehensive technical support. That means a detailed installation manual, video guidance for commissioning and operation, and remote online support. Engineers are available for on-site installation and commissioning. Spare parts are manufactured and stocked in house and ship in days. Every consumable also carries an open part number, so you are not locked into a single source.

What information do you need to quote this machine?

Four numbers decide the configuration: maximum part size, load per square metre of belt, required hourly throughput and target cleaning grade. Add the material, and whether any non-ferrous media or explosion protected dust collection is needed. Send your part drawing, material, maximum dimensions, weight and required hourly output. We then confirm belt width, wheel count and media specification before you order.

17. Talk to an engineer about your configuration

Send us your part drawing, material, maximum dimensions, weight, daily tonnage and required cleaning grade. Before you order we confirm belt width, wheel count and media specification. We also report the Sa grade achieved on your sample parts. Free blast testing is available on your actual parts. Hourly output is calculated per project from your part data. It is not quoted as a fixed catalogue number. Figures above are indicative and subject to confirmation per model.
