As the working chamber by a jaw crusher movable jaw and fixed jaw constituted under enormous crushing force composition and friction materials , easily worn , in order to protect the jaw , Yifan Machinery moving jaw and fixed jaw Ann resistant surface mill liner, this liner is also known as broken boards. Surface usually made of broken plates tooth , broken tooth plate angle of peak 90 ° ~ 120 °, its size is determined by the nature and degree of the block depending on the material to be broken , broken chunks of material , the angle should be bigger ; crushing small block material , the angle can be smaller . Particle size of the product depends on the pitch , usually about equal to the discharge port take the width of the tooth and the tooth height ratio of preferably from 1/2 to 1 / 3 . Work, crushing the two parts wear rate is not the same , the lower wear out faster than the upper , crushing jaw crusher plate work in direct contact with the material , under enormous crushing force and friction materials ,
