Is there a direct link between the size of the shot blasting machine and the cleaning effect?

The size and capacity of the shot blasting machine directly influence the cleaning outcome. The power of the machine and the velocity of the abrasive media are key factors 

affecting the results. High-power machines generate higher velocities and impact forces, thereby more effectively removing dirt, rust, and scale from the workpiece surface 

and improving surface cleanliness. However, excessive power can cause over-impact, leading to pitting or deformation, which in turn degrades surface quality. Low-power 

machines are suitable for parts with minor surface contamination; they provide gentle cleaning without damaging the workpiece surface, though cleaning efficiency is lower.

Additionally, the volume of shot blasting affects the cleaning outcome. Both excessive and insufficient blasting can impact efficiency. Overly intense blasting can lead to 

excessive surface hardness, affecting subsequent processing performance, whereas insufficient blasting fails to achieve the desired cleaning effect. The appropriate amount 

of shot should be determined such that the ratio of the actual weight of the shot thrown at the casting to the weight of the casting itself is between 10:1 and 20:1. The specific 

ratio should be selected based on the complexity of the casting.
