With the continuous development of grinding technology, there are two kinds of cement grinding equipment with lower energy consumption, one is vertical roller mill, and the other is roller press. The two types of equipment are different in grinding mechanism, structure design, and product performance, but each has its own advantages. 1.
WhatsApp: +86 18838072829The purpose of a cement mill is to grind and blend raw materials for use in the production of cement. These raw materials may include limestone, clay, shale, iron ore, or other minerals. The resulting powder is then mixed with water to create a paste that can be hardened through a chemical reaction known as hydration.
