TEETH PLATE FOR JAW CRUSHER, JAW CRUSHER AND SELF-TRAVELLING CRUSHER

摘要

PROBLEM TO BE SOLVED: To provide a teeth plate for jaw crusher which is capable of materializing high efficiency of crushing without making particle size of discharged crushed particles coarse, hardly causes degradation of efficiency of crushing and hardly produces excessive-load-applied parts, and to provide a jaw crusher and a self-travelling crusher provided with the teeth plate for jaw crusher.;SOLUTION: In the teeth plate for jaw crusher fitted to at least either of fixed teeth and movable teeth, material to be crushed is supplied into V-shape spaces formed by the fixed teeth and the movable teeth, the movable teeth plate swingingly moves for the fixed teeth plate 600 and, thereby, the material to be crushed is crushed. When the teeth plate for jaw crusher is fitted to at least either of fixed teeth or movable teeth of a jaw crusher, a crushing surface 601 is formed in a wave shape along a direction orthogonal to the direction of supplying the material to be crushed, wherein the pitch of the teeth constituting the wave shape has a part that becomes small from the upstream side of the direction of supplying the material to be crushed toward the downstream side thereof.;COPYRIGHT: (C)2007,JPO&INPIT
