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.

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.

The VRM is a type of grinding mill that uses a vertically oriented, multi-level cylindrical roller to grind materials into extremely fine powders. The key components of a VRM are the grinding rollers and the grinding table. The grinding rollers are hydraulically loaded and held against the grinding table by means of hydraulic cylinders.
