Jaw Crusher | Cone Crusher | Stone Crusher. A Jaw crusher uses compressive force for breaking of particles the mechanical pressure is achieved by the two jaw of the crusher of which one is fixed while the other moves back and forth relative to it, by a cam or pitman mechanism. The inertia required to crush the material is provided by a weighted flywheel that moves a shaft creating an eccentric

A Jaw Crusher or Toggle Crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it is small enough to escape from the bottom

This paper sets out to perform a static force analysis of the single toggle jaw crusher mechanism and to obtain the force transmission characteristics of the mechanism. In order to obtain force transmission metrics that are characteristic of the structure of the mechanism, such influences as friction, dead weight, and inertia are considered to be extraneous and neglected.

Jaw-crusher Construction. Jaw crushers are heavy-duty machines and hence must be robustly constructed. The main frame is often made from cast iron or steel, connected with tie-bolts. It is commonly made in sections so that it can be transported underground for installation. Modern jaw crushers may have a main frame of welded mild steel plate.

The jaw crusher is composed of two jaws, one is fixed firmly with the crusher frame, and the another is being mount by a pitman mechanism. The moving jaw moves backwards and forwards quickly between a small throw to crush the ore. As the moment of jaw plate is small, the crushing can be done in one stroke.

The pin is 2-1/2 IN solid round stock. The knuckle is a 2-1/2 section of well casing. The jaw will be welded to the knuckle and will pivot around the pin. So the bottom of the jaw seen in this pix will travel an arc as the other end of the jaw rides on the eccentric shaft. A small arc but an arc nonetheless.
