Jaw crusher working principle and maintenance

Jaw crusher is widely used as primary crusher in mining industry, it is important to know jaw crusher working principle and get more information about how to maintain jaw crusher. DSMAC is a jaw crusher manufacturer in China, the excellent experts will thell you some details about jaw crusher working principle and maintenance.

Jaw crusher application and structure:

Jaw Crusher is a common type crusher that is normally used for mining, quarried materials and recycling. It is mainly used to crush kinds of mining stones primarily, and the largest compression resistance of the material is 320MPa.

The main structure of jaw crusher contains: fixed jaw plate, side plate (up), movable jaw plate, jaw, toggle plate, tension device (spring and tension rod), side plate (down), pulley, bearing, eccentric shaft, fly wheel and so on.

Jaw crusher working principle:

The jaw crusher has many kinds of structures while their working principle are similar. This working manner of jaw crusher is hyperbolic extrusion. And its working principle is as follows. Through the motor’s wheels, the eccentric shaft is driven by the belt and the belt wheel to make the jawstock move by a regulated track. The angle between the toggle plate and jawstock will become large as the up of the jawstock. This will push the moveable jaw plate towards the fixed jaw plate, which can realize the multi-crushing of the materials. The angle between the toggle plate and jawstock will become small as the down of the jawstock. The moveable jaw plate will leave the jaw plate at the pressure of the tension rod and spring , meanwhile ,the final products will be discharged from the discharge opening. Along with the continuous rotating , the crusher will complete the periodic crushing and discharging movement ,which can realize the batch process.

How to maintain jaw crusher to mark it has a longer work life and higher working efficiency?

1.Daily Maintenance Lubricating Parts:

Lubricating parts are used to adding lubricant conveniently and reliably into the needing parts of the crusher. (This machine has four parts that needed lubricant: the four shaft bearings.)

2. Lubrication:

Frist, to make sure that the machine can work well and has long working life, please add lubricant in time (add lubricant every 3-5 days).

Second, the lubricating grease that needs to add into the plate of shaft bearings is 50%-70% of total volume of the plate. Please add every 3-6 months. Please clean the roller path of rolling bearing carefully with clean petrol or kerosene before adding lubricating grease. Oil drain hole should be opened during cleaning.

Third, the lubricating grease is chosen according to different climate and district. Calcium base grease, Sodium base grease, and calcium-sodium base grease can be used. Use the mixture of thin oil and lubricating grease if the lubricating grease is too dry.

Fourth, lubricating grease need to be added into the joints of toggle plate and its underlay during installing and repairing.
