Shot blasting equipment is mainly made up of roller special trolley, shot blasting chamber,shot blasting machine bearing mechanism, shot blasting machine, screw conveyor, bucket elevator 3 sets, air separator 2 sets, shot storage bucket 2 sets, shot controller 2 sets, Rotary Screen Machine 2 sets, chamber top sealing device, guide rail, dust removal system and electric control system (including dynamic simulation monitoring system) . RE21 main technical parameters:
1. Roll material and hardness: 9Cr2Mo hardness 85-95HS 9Cr3Mo hardness 90-100HS Roll Size:510-5604120(reinforcement zone 1900)
2. The treated Surface roughness: RA0.5 ~ 20.1 M for skin pass roll, and RA2.5 ~ 50.1 M for roughening roll.
     According to the diameter of common rolls, the roughening machine is divided into RE16, RE21, RE24, RE30 and so on. For example, RE21 main texturing diameter of about 21"roll.".
