The workpiece processed by the roller table shot blasting machine can not reach the expected effect, and the reasons are investigated from these aspects:
1, less pellet material
Elimination method: insufficient punching force, increase the amount of steel sand shot;
2. The workpiece is seriously rusted or has dirt
Elimination method: the dirt on the workpiece is cleaned in advance to extend the shot blasting time;

3, the shot blasting amount is not enough

Elimination method: adjust the position of the valve plug plate;

4, the pellet size is not appropriate

Elimination method: abrasive type is too small, or wear serious need to add new steel pellets;

5. The throwing area is unreasonable

Elimination method: adjust the position of the directional sleeve of the shot blasting device;

6. Pellet clumping or too long use

Elimination method: replace the new shot peening;

7, roller conveying speed is too fast

Elimination method: Adjust the roller speed.
