Jaw Crusher Working Function


This series of jaw crusher  can reach the crushing ratio of 4-6 and the shape of final solution is even. They are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, building materials, marble, and so on. The pressure resistance strength is under 200Mpa, suitable for major crush.Jaw Crusher can be utilised in mining, metallurgical market, construction, road and railway constructing, conversancy, chemistry, etc.

This jaw crusher  utilizes motor as its energy. By way of the motor’s wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. For that reason, the supplies in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening.

Jaw Crusher Functions:

1) straightforward structure, easy maintenance
2) steady overall performance
3) Flexible capacity
4) More than loading protection
5) steady performance
six) steady functionality

Jaw Crusher Operating Principle

This operating manner of jaw crusher is hyperbolic extrusion. And its functioning principle is as follows. By means of the motor’s wheels, the eccentric shaft is driven by the belt and the belt wheel to make the jawstock move by a regulated track. The angle between the toggie plate and jawstock will become large as the up of the jawstock. This will push the moveable jaw plate towards the fixed jaw plate, which can realize the multi-crushing of the materials. The angle among the toggie plate and jawstock will turn out to be small as the down of the jawstock. The moveable jaw plate will leave the jaw plate at the presure of the tension rod and spring, meanwhile, the final items will be discharged from the dischargeing opening. Along with the continous rotating ,the crusher will comlete the periodic crusing and discharging movement, which can recognize the batch approach. Compared with the single toggle jaw crusher,the oscilation jaw crusher characteristics light weight, simple components ,compact structure, and finely plump crushing top quality production. And also the supplies can suffered evenly crushing and the final merchandise can be forcedly discharged out by the decrease end of the moveable jaw, which have improved the higher production efficiency by 20-30%.

Jaw Crusher Functioning Feature

The jaw crusher can be utilized as the coarse and mid cruhsing in the field of mining, creating supplies and building, etc.  According to the width of the feeding hopper, the jaw crusher can be divided into three sorts :big ,mid and tiny. And the massive size is the machine with the feeding width of over 600mm and the mid size is at the variety of 300-600mm, and the modest size is significantly less than 300mm.

The operating parts of the jaw crusher are two pieces of jaw plate and 1 is the fixed plate (fixed jaw), which is vertically fixed on the front side wall. Although the other is the versatile plate( moveable jaw),which is positioned slopely and kind a crushing cavity (functioning cavity) with the fixed jawplate. And the moveable jawplate will periodicly close or leave the fixed jaw plate. When they leave each other, the supplies will enter the crushing cavity and the final merchandise will be discharged from the bottom of the machine. And when they close with each and every other, the materials in between the two jaw plate will be crushed by the extrusion, bending and crack.
