Jaw crushers are mainly used for medium-size crushing of various ores and bulk materials. The jaw crusher is widely used in mining, smelting, building materials, highway, railway, water conservancy and chemical industries. In order to better use the jaw crusher, it is important to understand the usage methods and key points of the jaw crusher.

(1) Preparation work before starting the jaw crusher
1. Carefully check whether the lubrication of the bearing is good, and whether there is enough grease at the joint of the toggle plate in the bearing.
2. Check carefully whether all fasteners are fully tightened.
3. Whether the protective device is good or not, if any unsafe phenomenon is found, it should be eliminated immediately.
4. Check whether there is ore or other debris in the crushing cavity, if any, remove it immediately.

(2) Starting of the jaw crusher
1. It can be started only after inspection and proof that the machine and transmission part are in normal condition.
2. This machine can only be started under no load.
3. After starting, if abnormal conditions are found, s* immediately, and start again after finding out the cause and eliminating hidden dangers.

(3) Matters needing attention when parking The parking sequence is opposite to the driving sequence, that is, follow the direction of the production process; The lubrication and cooling system must be s*ped after the crusher has s*ped, and the circulating cooling water in the bearing should be discharged in winter. Avoid the bearing from being frozen and cracked; After shutdown, clean up and inspect all parts of the machine.

(4) Lubrication The connecting rod bearing, eccentric shaft bearing, and elbow of the thrust plate of the jaw crusher are lubricated with lubricating oil. It is more appropriate to use No. 70 mechanical oil in summer. No. 40 machine oil can be used in winter. If the crusher is always working continuously, there is an oil heating device in winter. If the ambient temperature in summer is not too high, you can use No. 50 mechanical oil for lubrication.
