Blast wheel including blast whee housing, motor, blade, control cage, distributor, and guard plate.

Guard plates in the blast wheel are designed according to abrasive shot and blades rotating track simulation. After accelerating along the round track, abrasive can reach the highest speed and cause the least self-wear.

The direct-driven motor has a low noise level, fewer spare parts, higher energy efficiency, large abrasive flow rate, and good cleaning effect, etc.

Max thickness of guard plates is up to 70 mm, the service time is greatly increased. Material for core components is high chromium wear resistance alloy, max hardness is up to HRC55-60.

Automatic abrasive reclaim system including screw conveyor, bucket elevator, separator, abrasive cleaning up system.

Screw Conveyor

Cylindrical machining process after the whole weldment to ensure high coaxiality of the whole screw, for longer surface time. 

3-layer labyrinth design sealing to protect bearings from the damage of abrasive shot.

Bucket Elevator

Cage-shape belt driving wheel offers higher friction to the belt to avoid slip, decreasing the elevating belt pre tightening force

Maintenance door at bottom of the housing to maintain the bottom drive device.

Wear-resistant elevator buckets bolted onto elevator belt, tension device prevents the belt to skid.

SQP sensor can alarm and automatically power off when faults happened in bucket elevator.

Separator

A full-screen curtain air selection separator makes the abrasive more evenly dispersed, and takes the dust and other residues that may be contaminating the abrasive material to the exhaust system.

Optionally, the abrasive materials purifier can be supplied with a revolving screen.

A checking window allows workers to maintain the machine expediently.

Abrasive Cleaning Up System

An abrasive cleaning up system is used for the roller conveyor shot blasting machine and preservation line.

The abrasive cleaning up system is equipped with a wear-resistant nylon roller brush, screw conveyor, high-pressure blower, and lifting mechanism.

After shot blasting, the lifting mechanism lowers the roller brush to the most suitable position (make the roller brush contact with the workpiece), rolling and rotating, sweeping the left abrasive on the workpiece surface into the screw conveyor. Meanwhile, the high-pressure blower continues to clean scattered pellets and dust on the surface, make the surface clear.

Nylon roll brush with high elasticity and phi 3.5mm imported composite nylon material, moderate hardness, great elasticity, and good wear resistance.

3-level dust collector: settling chamber, cyclone dust collector, and cartridge filters. Cleaning efficiency is up to 99.5%.

The filters use cartridge type filters, a vertical fixed unique structure is greatly convenient for maintenance and collecting dust.

The filter adopts the Venturi principle venturi tube pulse blowback dust collecting system for clearing the dust on the filter.

The blast wheel is the core component that accelerates steel shot to high velocity by centrifugal force. Abrasive is fed into the center of the rotating wheel and thrown out through the control cage at a preset angle.

Wheel blades are made of high chromium cast iron with a long service life. Their special curve keeps an even abrasive pattern and a stable blasting effect on the workpiece surface.

The wheel assembly is mounted on a heavy-duty bearing housing outside the chamber, so it can be inspected or replaced without entering the blasting zone.

The reclaim system separates reusable abrasive from dust and fines, then returns it to the blast wheel automatically. It keeps abrasive quality stable and greatly reduces consumption.

A bucket elevator lifts the mixture from the hopper to the air separator, where a cross-flow air stream removes broken grit and dust. Clean abrasive falls into the storage hopper for the next cycle.

The system works continuously with the machine, so production is not interrupted for manual screening and refilling.

A cartridge or bag type dust collector is connected to the chamber outlet. It captures the dust generated during blasting and keeps the workshop air clean.

The filter elements are cleaned automatically by a pulse jet system, and the collected dust is discharged into a sealed bin, which makes the shot blasting process environmentally friendly.

Air volume is matched to the chamber size so that a slight negative pressure is always kept inside the machine and no dust escapes from the inlet and outlet openings.
