Product introduce
Sand blasting room is also called shot blasting room and sanding room.
Sand blasting is a method of finishing the external surface with high-speed gravel. It can remove oxide skin, grease, paint skin, etc. on the surface, and obtain uniform surface quality. Subsequent processes can be welding, oxidation, coating, surface chemical heat treatment, phosphating, etc. Sand blasting can cause residual compressive stress on the surface of the workpiece and make the surface quality of the workpiece uniform, which can improve the fatigue strength of the workpiece. The strengthening effect is worse than shot blasting, and the deformation of workpiece is smaller than shot blasting.

Product structure

1.Mainly composed

With the Blasting Room, Air Blasting System, Sand Circulatory System, Dehumidify System and Dust Collector.

2.Abrasive Reclaim System
The reclaim system is determined by the type of abrasive being used, (screw conveyor vs.vacuum reclaim), your production requirements andbudget. Full reclaim floors are more costly but provide
continuous automatic recycling of abrasive. Partial reclaims and corner boxes require the operator
to sweep the abrasive to the reclaim system.If your parts are to be handled by forklifts, the reclaim
system must accommodate heavy floor loading.
3.Control system
PLC control, Error warning system on abrasive circle system, any error come, the above work will stop automatic.Control function underAutomatic control, hand controller and maintenance states will be control, so there are cascading protection feature among each process.
4.Dust remove system
Abrator dust stream generated when working through the primary separator and connecting pipe,
and then flow into the deposition of dust box, large particles are deposited, a small pipe into the dust and then by pulse jet bagfilter. Emissions of dust concentration after not more than 80mg/m3, in line with the provisions of the National Environmental Protection
Agency emission standards not higher than 120mg/m3.
5. Shot distributing system
This machine adopts the patented shot valve produced of our company; it can accumulate a certain time in blast-peening, through themanual control to provide the shot ball to the blast-peening device.
