What is a Jaw Crusher? – MEKA Crushing Equipment

The working principle of jaw crushers is based on the reciprocating movement of the movable jaw that compresses and crushes the rock or ore between itself and the fixed jaw, as the material enters the zone between the jaws. The moving jaw moves back and forward against the fixed jaw, and material fed from the top of the machine is compressed between the two, breaking it into smaller pieces. As ...

Jaw Crusher - an overview ScienceDirect Topics

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 jaws are usually constructed from cast steel and fitted with replaceable ...

Analyzing the operation and design of a Jaw Crusher using ...

14/08/2019  A jaw crusher is a device that reduces the size of various solid materials in many applications, including underground mining and mobile crushing applications mainly using the compressive force of the two jaws, one of which is stationary and the other is moving. The jaw crusher’s moving jaw undergoes two main types of motion, one resulting from the eccentric shaft movement,

Crusher - Wikipedia

A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber. The movement of the swing jaw can be quite small, since ...
