Jaw crusher is widely used in mining, smelting, building materials, road, railway, water conservancy and chemical industry and other industries in the medium-sized crushing of various ores. The maximum compression strength of the crushed material is 320 MPA.

Jaw crusher is the main equipment in mining, should be used carefully, the maintenance method is as following:

Stop jaw crusher regularly, check the machine, check the internal wear of the machine, replace the worn parts in time and repair it. At the same time pay attention to the weight and size of the replacement parts, should use the parts based on original parts parameters.

Check the jaw crusher belt conveyor regularly. Jaw crusher belt conveyor indispensable in the stone production line. Regularly adjust the tension of the conveyor belt to ensure uniform force on the conveyor belt. When using double motors driven, the V -belts should be matched in groups so that the length of each group is the same. If it is found that the belt wear worn is serious, please replace timely.

Lubrication of mechanical parts. The jaw crusher uses Mobil motor special grease or 3 lithium base grease, adding the right amount of grease every 400 hours; open the shaft assembly to clean the bearing working 2000 hours; to replace the new bearing working 7200 hours .

In order to ensure the normal operation of the crusher, the planned maintenance must be carried out in addition to the correct operation, including the daily maintenance, the medium repair and the major repair.
