The vertical roller mill or vrm cement mill is a popular equipment for raw material processing and cement grinding. Here are some factors we should pay attention to during the operation of vertical roller mill in cement plant.

Vertical Roller Mill: widely used in the cement industry for grinding clinker and raw materials. They are also used in industries such as mining and chemicals. In summary, while both ball mills and roller mills are used for grinding, they differ in their grinding mechanisms, design, and operation.

Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …
