Raw Materials Crushing, Storing and Grinding. Clinker calcination is the most crucial part of the whole process of cement manufacturing. At this stage, ground raw materials will be sent into the cement kiln and be heated at a high temperature to produce chemical reactions with each other, eventually forming clinker. In addition, clinkers that ...
