Its consumption per ton of clinker largely depends on the quality and also on how effectively the cement process technology is being used. Coal consumption varies from 0.2 to 0.3 tons for every ton of clinker. It is known that the indigenous cement plants are consuming at least 20%–30% more energy than those of similar plants in other countries.

The cement roller press has a high energy utilization rate and remarkable energy-saving effect in the material grinding process. In cement plant, cement roller press is a kind of important cement equipment used for clinker grinding. It is usually combined with a cement ball mill to form a high-efficiency cement grinding system because the practice shows that the grinding …

The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. Virtually all steel is now made in integrated steel plants using a version of the basic oxygen process or in specialty steel plants (mini-mills) using an electric arc furnace process.
