Jaw crusher is one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws (feed opening). For instance, a 24 x 36 jaw crusher has a opening of 24" by 36", a 56 x 56 jaw crusher has a opening of 56" square.

The pitman is generally given a nearly vertical motion by the eccentric shaft, and since one of the toggles is mounted in rigid state at one end of the crusher frame (Fig. 4.2 A), the reciprocating motion of the pitman causes the other toggle to move the jaw back and forth. Crushing is accomplished only when the swinging jaw moves towards the ...

Jaw breakers use an eccentric shaft to make the jaw move an inch and a half, at around 400 rpm. That makes 1500 engine rpm with a 540 rpm PTO. So i dont know if it will be direct drive with just a torsion damper to get maximum fuel efficiency, or with a 1:1.25 reduction so the tractor engine can run at 1900 to 2000 rpm to get more power.
