Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, …
The most used coal mills in cement plants are air-swept ball mills and vertical roller mills. At present, most cement plants use coal as the main fuel in the clinker production process. The standard coal consumed by the new dry process for producing 1 ton of cement clinker is usually between 100 kg and 130 kg, and the fuel cost accounts for ...
Raw Mill and Cement Mill are essentially two different processes in a cement plant. Raw Mill is mainly used to grind raw materials into fine powder, whereas Cement Mill is used for grinding clinker and other additives to form the final cement product. The main difference between the two lies in their respective input materials; …
For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance …
The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.
Comparison. When grinding raw meal, the unit power consumption of the vertical roller mill and the roller press is about the same, which is 7-8kWh/t. But the vertical mill is usually slightly higher. The system of the vertical grinding mill is simple and stable. It has ideal adaptability to material moisture and can achieve the goal of energy ...
