The mechanization and automation of carbon material producing is very important to satisfy the need in metallurgy, chemical industry, electron, aviation and nuke industry.

In the process of producing carbon, from raw materials to final products, there need to use many kinds of machinery. According to the production process, it can be divided into calcine, crushing, screening, store materials, feeding, preparing, mixture, molding, dipping, graphitizing and machining equipments as well as its auxiliary equipment. In this text, we will talk about the crushing principle.

Crushing principle:

The feeding of crushing materials and the adjustment of crushed material are important links in the crushing operation. When crushing, the principle of "no excessive crushing" must be observed. Over crushing often leads to lower quality of crushed materials, lower productivity and increased energy consumption. The following measures must be taken to achieve "no excessive crushing"

a. Try to "crush freely". To avoid "crush closely".

b. The material must be separated before crushing.

c. To improve the crushing ratio. Because the abrasion of the metal parts will lower the crushing ratio.
