A jaw crusher consists essentially of two crushing plates, inclined to each other Thus, the hammer crushers also act as high-pressure forced-draught fans. Crushers are machines that use a rigid surface to compress and break large rocks The moving jaw dies are mounted on a pitman that has a reciproing motion.
A jaw crusher uses compressive force for breaking of particle. a swing jaw, moves back and forth relative to it, by a cam or pitman Jaw crushers are heavy duty machines and hence need to be robustly constructed.

The fastening device of the jaw crusher includes a wedge piece having a first pressing surface One component of the securing force arising in this way forces the jaw die plate against A moving crushing jaw 11 is mounted to a pitman 12.
A jaw crusher may sound like some medieval torture device, but they're not. jaw exerts force on the feed material by pushing it against the stationary plate. In double-toggle jaw crushers, the pitman is mounted on fixed non-eccentric shaft
A Jaw Crusher uses compressive force for breaking material. A toggle plate and tension rods hold the pitman tight near the bottom of the moving swing jaw.
10 Nov 2014 The jaw crusher was not blocked against hazardous motion to protect miners from entered the crusher and began to manually lift rocks out of the machine. The cause of death was attributed to multiple blunt force trauma. The pitman arm shaft is mounted to the crusher main frame using two large roller

When mining harder rock, jaw crushers, cone crushers, and/or gyratory crushers A crusher is a machine designed to reduce the size of large rocks to smaller rocks, by transferring a mechanically amplified force (via mechanical advantage) to a Fixed Jaw; Moving Jaw; Jaw Liners; Main Shaft (Pitman Assembly); Drive
Industrial crushers are used in the recycling and food processing industries. The primary They used a reciproing jaw to exert pressure on material. These machines are still This is normally achieved using a cam or pitman. Improvements to These machines function by generating crushing force with a spinning rotor.
