2. Precautions


(1) In the range of φ 600 × 1500mm, the workpiece should be filled as much as possible, which requires the design and manufacture of a variety of suitable slings according to the size and shape of the workpiece. Only in this way, can the efficiency of the projectile ejection belt be fully exerted, and at the same time, the impact and wear of the empty shot on the guard plate of the rich and strong body can be reduced.

(2) When the hook is opened into the indoor center, it must be in place, then close the gate, press another travel switch, start the shot blaster, ensure the safety of operation and maintenance, and make full use of the throwing belt.

(3) Always check whether the projectile flow beam of the ball supply gate is full, and if the storage capacity of the projectile is insufficient, it shall be supplemented in time.

(4) If it is found that the vibration of the shot blasting machine is too large and there is abnormal noise, stop the machine immediately, check whether the blade of the shot blasting machine has unbalanced wear or fracture, and replace two symmetrical blades in pairs.
