1. Introduction. Portland cement clinker is a black nodular hydraulic material. It is made by burning in a rotary kiln (pyro-processing), at least to sintering a precisely specified mixture of raw materials containing CaO, SiO 2, Al 2 O 3 and Fe 2 O 3 at temperatures of about 1400 °C. Following the clinkering process in the kiln, clinker is cooled down in coolers.

Vertical roller mills (VRMs) have become the equipment of choice for raw and solid fuel grinding in cement factories. Increasingly modern cement plants also use VRMs for cement grinding. However, opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding.

The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

According to the calculation of the consumption of high chromium ball in each mill calculated by a cement enterprise for several years in a row, the consumption of high chromium ball in each mill is 50g / t for raw meal, 80g / t for cement grinding, 150g / t for tons of cement, and 450t / t for cement enterprises with an annual output of 3 million t cement.
