Crushing ways

Crushing ways introduction

crusher and discharging refers to say hammer apparatus of more than 3 mm size of content for more than 50% of the total row during crushing machine, commonly used a jaw crusher, impact crusher, etc. Broken by feeding and homework often discharging the size of the particle size is divided into crushing, broken and in finely. Breakage is a large material into small pieces of material process. The current in dressing industry is mainly by mechanical force to break ore, but according to different methods to force, crusher for material crushing destroy have extrusion, bending, impact, cutting and grinding method, etc.

Crushing

The material in two pieces of mining face between, after pressure, material in compressive stress to reach the compressive strength and broken, this method is applicable to general fitness broken large materials;

Grinding

Material and movement of the work between surface under certain pressure and shear force function, the shear stress to the material shear strength limit, material and broken destroy; among the materials or between the shear friction, grinding effect and make the material broken destroy;

Fold Broken

By the bending stress of the role and the material broken, material being broken under concentrated load of second protection function or more protection simply supported beam, when the material the bending stress of material to bending strength, namely be broken and broken;

Cut

The material for a plane and sharp edges with the working plane between, when pointed work of the edges with flat face in extrusion of materials, the material will pressure the direction along the lines of action splitting. Because of the split of the plane of the splitting tensile stress reach or exceed materials tensile strength limit. The tensile strength of the material limit than the compressive strength of the small a limit;

Impact crushing

Material impact and broken by function, its broken when the instantaneous force function, and the crushing efficiency is high, the big crushing ratio, energy consumption is small.

Summary

For now, in order to improve the crushing efficiency, in improving the existing equipment at the same time, there are many new broken the son ore methods, such as electric heat radiation, liquid electricity effect, heat and pressure broken ore and the use of the other energy of broken method, etc. But, these new methods are also knowledge primary research stage, no official get application, so, for the moment, or commonly used method of the above four crushing ways.
