Some common mistakes in the daily operation of shot blasting machines

1. Delayed shot delivery: Shot blasting machines use blast wheels to propel steel shot at high speed onto the workpiece surface for cleaning. The shot is a consumable material; if the machine load drops, an insufficient quantity of shot can disrupt the lifting and separation cycle, thereby affecting the quality of the blasting process.

2. Incorrect startup sequence: Failure to follow startup instructions—such as not opening the shot feed valve after starting the machine—results in the machine running idle without shot delivery.

3. Incorrect shutdown sequence: Prematurely shutting down the machine leaves shot in the feed system, which can easily cause the motor to burn out during the next startup.

4. Conveyor roller speed too high or too low: The rotation speed of the conveyor rollers is adjustable. Failure to adhere to speed adjustment guidelines can impact the quality of the blasting process.

5. Loose elevator belt: The elevator is equipped with a belt tensioning device, which can be used to correct a loose belt.

A loose belt prevents the elevator from lifting the shot, which can lead to equipment damage.
