Shot blasting machine deck by Grit Shot speed will impact the falling material in an object's surface treatment technology. Compared to other surface treatment technologies for Qinghai deck blasting technology, which is faster, more efficient, and part of the reservation of the casting process or after stamping. 1930s American companies made the first shot blasting machine in the world. China, shot peening equipment production began in the 50s of last century, mainly former Soviet Union imitation technology. Tight seal: Shot shell lined with chromium alloy liner. Liner is a labyrinth of overlapping each other, to prevent excessive wear and pellets leak, blasting the end shield and the top guard with a maze of curved multilayer protection technology bridge blasting, shot blasting tip additionally has cast iron and wear-resistant rubber seals Hubei double deck blasting, to ensure a tight seal, eliminating the projectile blast wheel casing breakdown phenomenon, excellent sealing effect.
