PCL Vertical Compound Crusher
PCL vertical compound crusher is widely used in the medium crushing and fine crushing field of the high-hard or extra hard material such as a variety of ores, cement, refractories, bauxite, carborundum, glass raw materials, etc.
The safe operation of the PCL vertical compound crusher
First, you should check if the storehouse door of the the compound crusher is closed tightly. Let the machine stop completely when you open the door of the storehouse in case of any danger.
Second, the crusher must be started with no load. Feed to produce when the machine is in normal operation.
Third, the feeding size should be according to requirements. Too large size will damage the equipment.
Forth, if the fine abnormality in the process of crushing, you should stop to check. You should continue to produce after troubleshooting.
Fifth, you should add lubricant to the rotating bearing parts regularly.
The cause of the damage and solutions of the motor of the compound crusher
The reliability and sensitivity of the automatic pressure switch may cause the damage. The start and pause of the compound crusher will achieve automatic control of the motor by the AC contactor,which is driven by air pressure automatic switch. The automatic pressure switch mostly uses mechanical structure with spring compression and energy release to actuate contact. Maybe the inherent problems of the automatic pressure switch like the improper regulation or the vibration cause the damage.
You should select appropriate model of the bearing of the rotor. The roller bearings of double-row centripetal spherical surface has the advantages of high bearing capacity and good aligning performance.You should select this kind of bearing as the rotor bearing. In addition, you'd better choose the bearing with design life of 5000-10000h.
