The cavity shapeof jaw crusher is set by the jaws and dynamic jaw by the formation of the space, it is the material of aqueous broken work space. Jaw crusher cavity shape design is good or bad, the crusher of technical and economic indexes (productivity, energy consumption, crushing the granularity of product and grain shape and crushing wall and rolling out wall wear, etc) influence.
To the traditional jaw crusher cavity shape for design improvement, the new design cavity shape processing capability, and 15 to 25% of high moisture, improve the adhesion of ore 30 to 50%. Visible, reasonable design cavity shape can greatly improve the productivity of the crusher, so as to improve the economic benefit. Users crusher To the traditional jaw crusher cavity shape to transform, a good effectiveness has been obtained. Row ore grade of fine grained greatly increased, finely row mine in less than 15 mm of grain of class content increased from 44.85% to 60.47%, more than 20 mm of grain content level by 26.13% to 16.33%. In addition, before modification cavity shape processing power consumption per ton for 0.960 kWh undressed ore, new cavity shape processing power consumption per ton for 0.804 kWh undressed ore. Visible, to design the reasonable crusher cavity shape can greatly improve the productivity, improve product broken crusher size and grain shape, reduce energy consumption, so as to improve the broken homework user of the economic benefits. Crusher Therefore, the jaw crusher and also hammer crusher cavity shape research is a very valuable work.
Jaw crusher cavity shape design not mature theoretical guidance, general according to engineer experience, with the single particle materials broken for design principles, the principle that crushing cavity to, discharging mouth size and parallel area length design requirements, satisfy the relevant crushing cavity tooth Angle can effectively fastened on single particle materials, crushing cavity is often straight line or broken line cavity shape. However the production practice showed that, according to the design engineer experience crushing cavity low productivity, high in energy consumption, the broken product size and grain shape is poor, fine grain content low broken products, mainly to needle flake, especially exists serious congestion and qa department phenomenon, to meet the requirements of the relevant use department. To effectively improve the crusher work efficiency, reduce the energy consumption and enhance the crusher broken productivity, improve crushing the granularity of product and grain shape, the broken grinding field requirement to layer for the modern high pressure broken extrusion crusher cavity shape design principle.Jaw crusher:http://www.crusher-machine.com/1.html

Especially in recent years, scholars have finely jaw crusher in-depth study, puts forward the principle of fixed volume, finely developed jaw crusher cavity shape curve of pressure, which has greatly enhanced the work performance, crusher broken jaw crusher cavity shape research to provide a new method. Based on the layered broken properties, with the existing research results, the crushing cavity jaw crusher work performance study, puts forward the fixed quality into the principle, for research and development of new and high efficient crusher theoretical foundation.
