① Adjustment of equipment such as shot blasting machine, different shooting angles of steel shot, the faster the shot blasting speed, the greater the consumption of steel shot, the inner side wall of shot blasting machine is not repaired in time after damage, the shot blasting process takes a long time, The top rail of the shot blasting machine is not sealed, and the scattered steel shot is not recycled in time, which can affect the utilization efficiency of the steel shot.
② Surface roughness of the material to be cleaned. The higher the roughness, the greater the consumption of steel shot.
③ The amount of sand sticking or rust grade on the surface of the workpiece to be treated.
④ The hardness of the workpiece and the cleanliness level of the cleaned workpiece.
