Cement roller mill is a typical energy-saving and high-efficiency grinding device, which is based on the principle of high-pressure material bed grinding. It is widely used in drying and grinding of various materials. In the cement production process, it is mainly used for raw meal grinding, pulverized coal preparation and cement grinding. Cement clinker has poor abrasiveness, high abrasiveness, good fluidity, fineness of finished products and high requirements for cement performance. The technical requirements of cement grinding for roller grinding device are the most stringent. Over the past decade, the development of world-renowned roll mill suppliers has focused on cement roll mill, and new developments in roll mill specification, driving mode, mill structure and design parameters are worth learning.
