Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
grinding. Cement grinding Grinding of cement with RPs in finish mode has not yet seen a significant uptake and cement producers remain somewhat reluctant to use RPs in this set-up.

portland cement that needs to be produced, is then ground together in a fine-grinding mill to make portland cement. Portland cement is used both as an end-use product and also as an intermediate product in producing different types of blended cement (FHWA 2008).
Diamond grinding method uses a close network of diamond saw blades that graze away uneven concrete bits. The blade runs on surface many times to ensure smooth surface. These grinders lead to a longitudinal finish on macroscopic level. This longitudinal texture provides safe ride, skid resistance and lesser noise.
The OK™ Mill was originally designed for cement grinding. In 2017 we released the OK™ vertical roller mill for raw materials grinding. The OK™ Mill's modular design comes with unique flexibility, showcasing parts commonality, where spare parts can be shared between vertical roller mills regardless of size and application.
