jaw crusher main shaft

Moveable jaw stock The moveable jaw stock is the main moving part in a jaw crusher. It forms the moving side of the jaw, while the stationary or fixed jaw forms the other. It achieves its movement through the eccentric movement of the crusher main shaft. It is the back and front (to and fro) movement of the moveable jaw stock that gives

Figure 8.1 shows two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is installed on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action of the moving jaw. A double toggle crusher has, basically, two shafts and two toggle plates.

The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle plates. The chewing movement, which causes compression at both material intake and discharge, gives the single toggle jaw better capacity, compared to a double toggle jaw of similar size.

Jaw crushers process medium to hard quarry rock or other materials by compressing it between the fixed jaw and the swing jaw. The swing jaw being the moving part is attached to a rotating eccentric shaft. The fixed jaw is an integral part of the crusher frame. Both jaws are fitted with manganese jaw liners that can be replaced or reversed when worn.

Jaw crusher is one of the important crushing equipment in mining industry. It has the incomparable advantage of stable and reliable operation, easy maintenance, long service life, less dust and noise. Eccentric shaft, the main drive part plays an important role in the operation process.

Jaw Crusher Main Shaft. The pitman is put in motion by the oscillation of an eccentric lobe on a shaft that goes through the pitman's entire length. This movement might total only 1 1/2″ but produces substantial force to crush material.
