2. Check the quality of steel cleaning frequently. If necessary, adjust the projectile projection angle and roller conveyor speed. Observe whether the steel is deflected or slippery at any time. If necessary, remove it in time.


3. Pay attention to whether the vibration and sound during the operation of the shot blasting machine are normal, the temperature rise of the bearing and the motor, when there is an abnormality, stop and check, troubleshoot or replace the blade.


4. When the shot blasting room is finished, the shot pipe should be closed first, the air intake should be stopped; the motor should be turned off, and the ventilator should be stopped at last.
