The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments
There is no doubt that cement grinding mill and cement roller press are the core equipment of cement grinding unit. Cement grinding machine selection will directly decide the quality and cost of whole cement grinding unknit. According to the real cement projects, there are three common solutions for cement grinding plant.
In the case of Slag grinding, the acceptance of roller press in finish grinding is well recognised. It offers the distinct advantage of saving of about 67 Kwh/t as compared to Vertical Roller Mill at 4200 Blaine. KHD has sold 27 Sag Grinding Circuits and maintains about 70 % market share in slag grinding in India.

This case study is to identify and evaluate the root cause for failure of a roller press mill. Cement plant has a heavy crushing operation the roller's top surface is eroded, which is replaced by hard metal deposition by welding. In manufacturing, most of the steel metals are failing by either fatigue or by hard deposition through welding.
The power ingesting of a grinding process is 5060% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
