Jaw Crusher - an overview ScienceDirect Topics

Since the comparative reduction capacity of the jaw crusher is given, the crusher dimensions may now be determined. For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7

“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. Generally primary jaw

DESIGN AND ANALYSIS OF IMPACT CRUSHERS

Introduction A crusher is a machine designed to reduce large solid chunks of raw material into smaller chunks. Crushers are commonly classified by the degree to which they fragment not starting material with wares crushers not reducing it by much, intermediate cruiser fragmenting it much more significantly and grinders reducing it to a fine power.

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 complete
