EFFECT OF GRINDING METHOD ON ENERGY CONSUMPTION AND PARTICLE ...

In the conventional process of cement production, 30–80 kWh/t specific energy is consumed in cement grinding which equals 30% of the total energy consumption. Furthermore, approximately 60–70% of the total electrical energy used in a cement plant is utilized for the grinding of raw materials, coal, and

Cement Grinding Aids - Penta Chem

The cement grinding aids is additional material in liquid or solid form, admixed in small amount during the cement clinker grinding process which can significantly improve the grinding efficiency and reduce energy consumption, without compromising the performance of the cement. The cement grinding is an energy intensive process.

energy consumption. By using a high pressure grinding roll (HPGR) in pre-grinding or semi-finish grinding mode, savings of specific energy consumption up to 30% compared to ball mill in closed circuit can be achieved. The state-of-the-art technology is a HPGR in semi-finish grinding mode. For this, two types of air classifiers
