And with the lowest specific energy consumption among comparable …
The equipment costs are higher for a VRM than a ball mill, reflecting the greater complexity of the system, which includes items such as the rollers, table and the hydraulic system. Overall, when equipment, erection and civil costs are taken into account, the cost of a VRM project is around 20 – 25% greater than a ball mill system of the same ...
The main separating device is a cylindrical rotor. The rotor is like a cage composed of blades closely spaced. The rotor is operated by a variable speed drive. The rotor speed determines swirl in the classifying zone and therefore the cut of the separator. The material is generally fed at the top of the separator.
Cement Separator. Cement separator, also called a cement mill separator, is the necessary equipment in the powder classifying system of cement, chemical, mineral, and other industries. It can respectively collect the qualified fine powder and coarse powder from the airflow after they are ground by the grinding equipment to a certain extent.
