In jaw crushers, the crushing force is generated by the movement of the movable jaw plate towards the fixed jaw plate. This force is a result of the mechanical pressure created by the eccentric shaft and transmitted through the toggle plate. The interesting thing is how these forces are applied to the material.
Working Principal of Jaw Crusher. Lumpy test material to be crushed is fed into the crushing zone through a hopper. The crushing zone consists of two parallel side walls of hardened and tempered steel and two special profile Jaws.

Jaw crushers are an essential piece of equipment in many industries, from mining and construction to recycling and demolition. They are used to break down large rocks and other materials into smaller, more manageable pieces for further processing. One of the most critical components of a jaw crusher is the toggle plate, which plays a vital …
Double-toggle jaw crushers. In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. The toggle is kept in place by spring-loaded tension rod.

Jaw crushers are generally considered a primary or first stage crusher. The maximum feed size can be as large as 80%-85% of the crusher's gape or depth, while reduction ratios range from 2-3 times. Cone crushers are typically used in the secondary or tertiary stage after a jaw crusher's begun the reduction process earlier in the circuit.
A jaw crusher uses compressive force for breaking rocks into smaller pieces by placing the rock between two surfaces, one of which moves back and forth relative to the other to crush the rock. Jaw crushers produce coarse particle size ranges from 150-250mm and can be either single toggle or double toggle designs.
