[0002] Cement clinker is an important raw material in the cement production process. It is mainly made by calcining limestone, clay, iron ore and other mineral raw materials at high temperatures. The production process of cement clinker generally includes steps such as crushing, grinding and calcining. First, the raw materials are mixed in proportion and ground into a uniform raw material powder. Then, they are calcined at high temperature in a rotary kiln to finally obtain cement clinker. The quality of cement clinker directly affects the performance of the finished cement. Cement clinker is an indispensable and important component of modern building materials.
