The Technology Development of Jaw Crusher

Jaw crusher, including simple swing jaw crusher machine and complex swing jaw rock crusher two types,They are similar in their works, the trajectories of moving jaw have bigger difference.Simple swing jaw crusher,because of the moving jaw is hung on the supporting shaft,so when the moving jaw makes reciprocating motion,the trajectories of each point on the moving jaw is circular,and under the horizontal mining jaw crusher stroke is small,and mobile jaw crusher plant at the bottom of the moving jaw (row ore mouth) is the largest.Because of falling into ore crushing cavity,the upper are big ore block,It can not meet the necessary amount of compression,ore crushing large deposits of the upper,to crush many times repeatedly,It can be broken.Crushing load is mostly concentrated in the lower part of the crushing cavity,the jaw crushers china didn't work,which reduces the crusher production capacity.

Jaw crushers work part is two pieces of jaw plate, one is the fixed jaw plate (fixed jaw), vertical (or top slightly camber) fixed before in the body wall, and the other one is movable jaw (moving jaw), position tilt, and fixed jaw plate is formed under the big small crushing cavity (working cavity). Activities for suppressing the jaw with standard cone crusher fixed jaw do periodic reciprocating motion, and sometimes separate, sometimes close to.

Jaw crusher is suitable for all kinds of mok's hardness below level 7 materials coarse, medium and small.When it is used to finely, appropriate chooses finely jaw crusher.On the use of jaw crusher production process,We should control the feeding speed device and screening and inspection screening in advance,It can make the product granularity and the crushing reduce,improve the quality of broken products.
