（1）MCT-1022P11-12 Suspended chain through-type shot blasting machine
1)Scope of application of the equipment
The suspension chain through-type shot blasting machine is specifically designed for welded parts to remove powder, scale, rust, dirt, and welding slag splashes on the surface of the workpiece, presenting the original metallic color of the workpiece surface, eliminating internal stress of the workpiece, increasing the adhesion of the workpiece during powder spraying, and ultimately achieving the goal of improving the surface and internal quality of the workpiece.
The suspension chain through-type shot blasting machine produced by our company is manufactured by introducing German technology. The manufacturing process of our P series shot blasting machine is applied to the German company's TITAN shot blasting machine, TE steel shot flow control valve, intelligent filter core dust collector, cyclone separator and flow curtain separator in the suspension chain through-type shot blasting machine. To become a leading domestic technology and fully functional suspension chain through-type shot blasting machine suitable for most types of welding products.
l All components of the shot blasting machine system adopt laser blanking to enhance the precision of the products.
l The separator adopts flow curtain separation technology and is designed for working conditions where there is little dust from welded parts, enabling more effective separation of steel shot and dust.
l The dust collector adopts intelligent filter element type dust removal + cyclone separator, which makes the dust removal effect better.
l The bottom ash outlet of the dust collector is connected to a dust collection box, which automatically discharges ash. At the same time, it prevents the backflow of air during ash discharge, thus avoiding the intake of a large amount of fresh air. This reduces the self-ignition caused by the contact of dust with fresh air and the dust falling into the dust collection box below the dust collection bin.
