“Computer Aided Design of Jaw crusher”

Jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end. [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws .For instance, a 22 x 30 jaw crusher has an opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square.

Jaw Crusher an overview ScienceDirect Topics

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.

Jaw Crushers McLanahan

Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54” across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.

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
