But, cement manufacturing and the raw materials used in the process pose a fire or explosion risk. A fire or explosion in a cement manufacturing plant damages the property and or causes injuries or fatalities to workers. It is, therefore, important for all stakeholders to understand how to avert these dangers. Cement Manufacturing Process
The cement roller press is a type of material-crushing machine which is often used in cement plants. It usually works together with a ball mill to form a pre-grinding or final-grinding system for the grinding of raw materials, coal, and clinker.. Compared with the traditional tube mill and ball mill, the roller press has lower energy consumption and …
