forces during jaw crushers
How much do you know about jaw crushers?
During the working process of jaw crushing, the material is in direct contact with the jaw plate, and the jaw plate bears huge crushing pressure, especially for some materials with higher hardness. The strong force will cause the installation bolts of the jaw plate to be vibrated and loosen, thereby aggravating the wear of the jaw plate, or

How does a Rock Crusher Work
The 48 by 42-inch jaw crusher and smaller sizes are force-fed by an automatic high-pressure lubricator to the swing jaw, pitman, and main bearings as illustrated in Figure 1. A motor-driven pump forces the lubricant through pressure buildup cylinders and out to distributors which dispense a precise amount to each of the points on the bearings.

The Most Practical Jaw Crusher Repair and Maintenance
The lubrication of the interface between the parts of the jaw crusher is very important. It can minimize the friction generated during the operation, make the whole jaw crusher run smoothly, and extend its service life. Unlike gyratory crushers, the main lubrication used in jaw crushers is grease instead of oil.

Nonlinear Dynamics of a Jaw Crusher Taking into Account
Rock property inhomogeneity allocation assumptions are made. The effect of rock properties on crusher dynamics is studied. The processed rock is considered as a set of discrete elements with varying characteristics during movement along the jaw. The uniformal distribution of the properties of each element entering the treatment zone is considered.

Know-how
What kind of quality do Jaw Crushers achieve? Due to the forces applied by the jaws during crushing, the material it produces is usually low quality as the material will fracture through lines of weakness. The reduction ratio of a jaw is generally a 4 to 1 one. Therefore a jaw cannot produce high volumes of small quality product.
