We all know that the key factors of rock crushing effect has a lot of, crushing equipment quality plays a big role, of course, when crushing equipment are similar, what factors determine the effect of the material broken?That is the reason why the material itself.

Broken is crusher for material applying force to overcome rock ore internal cohesion between particles which broken separation process.Material is broken, the external pressure exceeds the material itself has the strength and toughness, so as to realize the effect of broken.How much of a mine crusher ability, there are many factors affecting the, which was broken material toughness will restrict the crusher equipment of production capacity.

The influence of toughness of broken
Mineral pressure rolling, cutting, hammer, tensile, bending and other external force resistance performance while shown resilience, it includes the brittleness, plasticity, and ductility, flexible, elastic, and so on mechanical properties.Generally speaking, most minerals are brittle nature.But some big and some small.Brittleness of minerals in the grinding are easy to be shattered, excessive mill.Brittle small is not easy to shatter, is not easy in grinding mill, crushing.Ductility most to have some natural metal minerals, they are easy to be in the ore into thin slices and less prone to ground into a fine particle, so the product particle shape is more special, more for thin sheet.Most flexible, flexible and elastic for some crystalline mineral fiber, such as asbestos, flake and product minerals (mica, molybdenite, etc.) has, these minerals crushing and dissociation is not difficult, but very difficult to smash into fine grained.Their particle shape grinding is more special, in grinding is easy to produce the phenomenon of selective grinding.For this kind of mineral crushing particle shape of grinding, often is the requirement of retain their natural crystal shape, such as asbestos requirements keep fibrous, retain flake mica requirements, so as to make the products with special function.When don’t choose this kind of mineral grinding, also should fully pay attention to the special shape product particle can obtain good effect.
