The reason why the jaw crusher is hot in work

The jaw crusher will be hot at work, for this problem, we found the technical staff to analyze the reasons for users. We all know that the jaw crusher is a large mining machinery equipment, in the work of friction between parts and material and equipment friction will cause heat, in fact, this explanation is not completely correct, not all the heating phenomenon is caused by friction, if there is abnormal heating phenomenon is damaging to the jaw crusher equipment.

Jaw crushers are commonly used for coarse crushing of ores, and general crushers cannot replace coarse crushing operations:

　　1. the oil pump is broken, the oil supply is not enough to cause serious friction of parts.

　　2. The running clearance between the bearings is too small, which will also cause abnormal heating due to excessive friction, and the clearance between the bearings should be adjusted.

　　3. The oil cannot be discharged normally.

　　4. The liner plate of the jaw crusher is not used properly.

　　5. Cooked material or abnormally hard material causes the crusher to overheat.

　　6. Inadequate clearance between the top surface of the eccentric bushing section and the lower surface of the bowl-shaped shaft frame, and poor oil flow.

　　7. The spindle bushing "collapses" on the top of the thin side of the eccentric bushing (this part is exactly opposite to the big gear).

　　8. Belt tension is too tight.

　　9. Improper lubrication of the jaw crusher with oil.

　　10. The frame bushing is trapped in the frame bore or the top of the frame bore is collapsed.

　　11. The output power of the jaw crusher is too large.

　　12. Ore discharge opening is too small.

　　13. The lubrication hole on the main shaft or carcass is blocked by dirt or other things.

Before, after and during the use of the crusher, it is necessary to review frequently if there is anything out of the norm to prevent it from happening.
