Portland cement manufacturing process can be divided into 6 steps: raw material crushing, pre-homogenization, fine grinding, clinker production, cement grinding, cement packing, etc. In these processes, we need the assistance of different kinds of cement equipment, such as cement kilns, cement mills, and cement crushers.

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker ...

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
