TUNNEL TYPE SHOT BLATING MACHINE

ABRABLAST Roller conveyor blast machines are suitable for the descaling, paint stripping, rust removal, roughening, and cleaning of work pieces such as sheet metal plates, profiles, beams, and pipes. Depending on the type of system, thin sheet metal plates up to massive steel profiles weighing several tons can be processed. Working speeds from 0.5 meter/min for a small roller conveyor machine to 20 meter/min for a heavy roller conveyor machine are achievable.
During processing, the work pieces pass through the pre-chamber, blast cabin, and post- chamber of the system – either one after the other or in batches on a roller conveyor. Depending on the type of system, shot blasting is carried out with precisely positioned blast turbines equipped with energy-saving motors. The blasting result is all-round, comprehensive, and always reproducible. Roller conveyor blast machines can be easily integrated into existing production lines. Despite their sometimes considerable size, thesystems are easy to maintain because the components can be conveniently reached through large access openings and inspection platforms.

Operations :

The equipment is comprised of in-feeding roller conveyor, shot blasting chamber, blasting turbine, shots recycle system, dust removing system, out-feeding roller conveyor and electrical control system etc.

Roller conveyor shot blasting machine is the preferred choice for steel raw material or fabrications. Loading bymotor-powered roller conveyor , roller conveyor speed can be adjusted suitable for thedifferent workpiece through VFD Drives. The photoelectric detection at the entrance can detect the position of the workpiece and accurately transmit the signal to the PLC. That means when the workpiece into blasting chamber the blast wheels will start to work, extending the service life of the guard plate in blasting chamber.

The entry vestibule is equipped with wear-resistant rubber curtains that prevent the escape of abrasive. The vestibule is sealed on the bottom by an adjustable scraper brush. After passing through the blasting zone, work pieces enter a combined brush-off and blow-off zone. Excess abrasive remaining on the work piece surfaces is removed and returned to the abrasive process loop.

This type of machine provides a blast stream from above, side and below to give a uniform clean finish on both surfaces. The abrasive is recycled in the shot blasting machine, from crosswise screw conveyor to longitudinal screw conveyor, then transported to the bucket elevator, then into the separator. From the separator, the abrasive can be used will into the storage bin, can not be used will come out the machine. The dust collector is a standard component that every shot blasting machine will be equipped with. The air volume of the dust collector and the number of filter cartridges can be adjusted according to the size of the equipment. That can meet the environmental protection requirements of every country.
