Abstract: Cement roller mill utilizing the principle of high pressure material bed grinding is a typical high efficiency and energy saving grinding device. It is widely used for drying and grinding kinds of materials. In the cement production process, it is mainly used for raw meal grinding, pulverized coal preparation and cement grinding. The cement clinker has poor grindability, high abrasion resistance, good fluidity, fine fineness and high cement performance; therefore, cement grinding has the most stringent technical requirements for the roller mill. In the past ten years, the development of world famous roller mill suppliers mainly focused on the cement roller mill. It has been developed in the fields of large scale, driving mode, mill structure, and design parameters and so on, which worth learning for us.
