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

The LVT classifiers do a good job in the separation of fines and do so with a minimum pressure drop. LVT classifiers offer improved separation which helps to increase the capacity of the mill, improving the quality of the cement – due to better size distribution – and can result in a reduction in the energy consumption in the kiln. Author Bio:

1. Introduction. Cement is an energy-intensive industry in which the grinding circuits use more than 60 % of the total electrical energy consumed and account for most of the manufacturing cost [].The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In recent …
The moisture content on the kiln raw materials is also higher than the cement mill feed, which is generally dry. ... as the above actions reduce the grinding efficiency and therefore increase the mill's power consumption. ... The increased capital cost may be a factor for many companies in current times when capital is short; certain ...
