Dec 24, 2021Mixed crushing is often used in cement production. Therefore, mixed crushing generally refers to a production process in which two raw materials are sent to a crusher in a certain proportion in cement production for crushing. Common types of mixed crushing include limestone and marl, limestone and shale, limestone and clay, etc.

This grinding is done using either ball mills or vertical roller mills (VRM). VRM uses the compression principle to grind the raw material. The main advantage of VRM is higher grinding efficiency and ability to accept material with higher moisture content. Normally the energy consumption level in VRM is 10 to 20 percent lower than in ball mills.

The cement production process, for example, starts with mining of limestone, which is then crushed and ground to powder. It is then preheated to save energy before being transferred to the kiln, the heart of the process. The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker.
