Constant Performance with Continuous Stress. Rock crushers are used in one of the first steps of cement production for the coarse grinding of the raw material mined as crushed material e.g. limestone or iron ore. The throughput of large plants that are mostly in operation round the clock can be several thousand tonnes of rock per hour.

· Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However despite these benefits applications of the vertical roller mill for cement grinding are less
