Indispensible Role of Jaw Crusher in Ore Beneficiation

AUTHOR: admin       DATE: 12 Sep 2012 06:53:45

One of the main crushing machines, jaw crusher is mainly used for coarse and medium crushing in the mining, building materials and infrastructure departments. According to the width of the material feeding mouth, this machine can be divided into large, medium and small type, and the jaw crusher has many advantages such as simple structure, easy manufacturing process, reliable working condition and convenient use and repair.


The crushing work of the jaw crusher used in the mining ore beneficiation process is very important since it influences not only the production efficiency of the ore beneficiation, but the economic index. The crushing granularity of the materials satisfies the production and technological condition of the physical beneficiation, so that high ore beneficiation efficiency can be achieved. The crushing process of the minerals is a big production link in the investment of the ore beneficiation production link, and jaw crusher provides suitable materials for the ore beneficiation, so the crushing effect directly influences the comprehensive economic benefits of the ore beneficiation work.

Jaw crusher has wide application in the ore beneficiation industry and has significant influence on the beneficiation work. In the ore beneficiation technology production process, the jaw crusher often has two stages of crushing, which is coarse crushing and fine crushing. The materials crushing lay material basis for the beneficiation.

This crusher adopts the electric motor as the power. The eccentric shaft is revolved by an electric motor through v-belts. It causes the swing jaw following the preconcerted path to crush the feeding material. Thus the material will be crushed in the crushing chamber which is composed of the stationary jaw plate, swing jaw plate and the liner plate. The material is discharged from the lower part of machine that is what you want.

Please carefully examine the fasteners, especially lubrication components and bolts, before the machine is started. Enough oil must be needed on each lubrication component. Fasten the loose bolts, clear the crushing cavity, and then start the machine. During the normal operation, even material feeding is important. Insufficient load or over load is not allowed. Moving jaw plate, fixed jaw plate, side guard plate and roof plate are wearing parts, and much attention should be paid to them.
