Introduction

The jaw crusher is widely used in the world market nowadays and has the features of the high reduction ratio, simple structure, and easy maintenance. It has two types, which are primary crushers and secondary crushers. The compressive resistance of the materials to be crushers is up to 320Mpa.The large and medium sized crushers are the key products in our company and stand in the front of the industry in the aspects of design and production.

Structure diagram

The Jaw Crusher is mainly composed of: the fixed jaw plate, movable jaw plate, frame,

upper and lower guard plate, adjusting seat, moving the rod, etc. Good understanding of jaw crusher

internal structure of jaw crusher can play a very important role when using process and problems

Jaw crusher in mining, building materials, construction sector is mainly used as a coarse crusher

and crushing machine. According to the material inlet width size is divided into large, medium

and small. Feeding port’s width greater than 600MM is a large machine, material inlet

width in 300-600MM as midrange, inlet width less than 300MM is minicomputer.

The jaw crusher has the advantages of simple structure, easy manufacture, reliable work,

convenient to repair and use.

Working principle

Jaw crusher working part is two pieces of jaw plate, a fixed jaw plate ( the fixed jaw ),

vertical ( or upper slightly camber ) fixed in the body on the front wall, the other is the movable

jaw plate ( jaw ), tilted position, and the fixed jaw plate forming large small

crushing cavity ( the working chamber ). The movable jaw plate toward the fixed jaw plate do

periodic reciprocating motion, sometimes separately, sometimes near. Separately, the material i

nto the crushing chamber, the finished product from the lower discharge; near, the material arranged

between two jaw plates crushed by extrusion, bending and splitting.

Futures

1) Firm structure, stable performance, large capacity, even producing granularity.

2) With the increase of production, our jaw crusher can greatly reduce the operating costs.

3) Convenient maintenance and economical running expense.

4) The large feeding opening and force-feeding action from the inward and downward eccentric movement of the swing jaw mean that our jaw crusher can increase the capacity .
