Quarrying, construction and production at the mine , the rock crusher jaw crusher is mainly used for direct materials , in addition to withstand compression, impact force , but also with the friction material . Mainly by its jaw and upper jaw bed liner components. Different hardness of stone crushing process, how to choose the identification jaw , yielding liner construction and troubled about many users crusher how much of a problem , the following our professional R & D engineers crusher for you to explain in detail the analysis of sorting and price factors methods.

Ore Jaw Crusher liner in the jaw with a countersunk bolt bed , during pad plastic material , such as lead, aluminum, zinc alloy plate or perfusion cement mortar , so as to ensure that the bed liner and jaw tight fit . High strength and wear-resistant liner high manganese steel manufacturing , with small white cast iron . Since the upper and lower wear liner speed is not the same , often made of vertical symmetry , can turn around and use the lower portion of the wear . Large jaw crusher liners often makes up the blocks, each block can be replaced by another, so that it may be appropriate to extend the liner of use.

Ore Jaw Crusher cast liner surface arranged longitudinally corrugated or toothed ribs , two peaks when installing toothed jaws and teeth lining the valley just opposite , working not only to the material to squeeze the role, but also give the bending and splitting effect. Figure 2-17 shows the various forms of rock jaw crusher liner ribs , teeth lining the peak angle is generally 90 ° ~ 110 °, depending on the size of the broken tooth pitch size requirements , and general high gear pitch ratio of 1:2 to 1:3 . Tooth height , pitch a small particle size is small , then the yield is low, the power consumption is large.
   When the ore crusher jaw broken very hard material , the ribs will generate lateral forces , which have an adverse effect on the axis of the movable jaw plate , in this case the best use of flat lining .
