Shot Blasting Machine Parts In The Wearing Parts
Jan 02, 2018

Shotblast machine crawler accessories wearing parts are mainly shot blasting machine, shot blasting machine is the use of centrifugal force will abrasive thrown at high speed, the impact surface of the workpiece surface oxide scale, rust layer, sticky sand or impurities flaking, or surface deformation And produce compressive stress. Shot pillows in the sub-pill wheel, orientation sets, blades and linings are the most easily worn parts. These parts have historically been made of cast steel manganese 13 (ZGMn13). High manganese steel after water hardness reaches HB180 ~ 220, its characteristics are in the larger extrusion pressure or greater impact load, the work surface hardening occurs, the surface hardness of HB200 hardened to about HB500 to have Good wear resistance.

However, in the actual work process, due to high manganese steel can not withstand the impact of abrasives and scratches, quickly worn away, so that parts of the service life is greatly shortened This not only increased equipment maintenance costs and far reduce the operation of equipment The rate increases the worker's labor intensity. The most commonly used abrasion-resistant materials in blasting machines are high chromium cast iron.
