Reduce mill excessive crush for energy saving

There are many classification methods of crusher. For example, crushers can be categorized by structure and model, or by crushing way, or by operation speed, or by force type, or by fineness degree.
The milling method is based on the physical properties of the material, the material block size and the required degree of refinement to select. For hard materials, by extrusion, bending and splitting; should be used for brittle materials, the impact and splitting; material block is large, splitting and bending; materials block small or discharge particle size is very small should be used to shock and grinding. If you choose to grinding method, it will crush difficulties or excessive crush phenomenon, both of which increase the energy in the process of crushing consumption.
When required high crushing ratio, the crushing operation should be carried out in crushing system. And the system is comprised by several crushers. Passed the crusher unit system, the particle size of materials is smaller and smaller, and finally reach the required particle size. In this crushing system at each stage should be selected appropriate milling machinery and crushed than to maintain the coordination between the various stages of production capacity. Meanwhile, in order to reduce excessive smash smash performance and reduce energy consumption, and also for screening or classification after each crushing operations. Crushed crushed before and after the particle size ratio is the size of the degree of change. Single smash machinery is, it is equal to the feed particle size and the ratio of the maximum particle size of the discharge; for crushing machinery composed of multiple crushing system, which is equal to the initial feed particle size and the final row the ratio of the particle size, or equal to a single smash mechanical crushing than the connected product. When using crusher broken material, commonly referred to as the crushing ratio.
A large number of industrial and agricultural production, crush work energy consumption is large. But in the crush operations, most of the energy input grinding machinery are converted into heat and absorbed by the crushing machinery, circulating air and smash materials directly used for material grinding, but only a small amount: in the broken machinery, generally no more than 10%; in the grinding machinery, often less than 1%.Therefore, in order to reduce energy consumption, you must select the appropriate grinding machinery, using the correct method of operation, the provisions of the crushing ratio and per unit time of production.
