Cement grinding optimisation Request PDF

The energy efficiency of ball mills for use in finish grinding is relatively low, consuming up to 30-42 kWh/ton clinker depending on the fineness of the cement (Cembureau, 1997;Marchal, 1997).

EFFECT OF GRINDING METHOD ON ENERGY

2021-5-3  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 clinker. As a result, a small gain in grinding efficiency can have a large impact on the operating cost of a plant [7-8].

Cement Grinding Unit Clinker Grinder AGICO Cement

The cement grinding unit adopts the pre-grinding technology. On the one hand, it reduces the particle size of materials before the formal grinding, on the other hand, it causes the cracks and defects inside the particles to greatly improve the output and reduce the energy consumption of the cement grinding mill.
