Cement Kilns: Size Reduction and Grinding

In processes such as cement milling, where the particle size has to be reduced about a thousand-fold, the product-sized particles produced in the early part of the process impede the grinding of the rest, and will tend to end up finer than they need to be.

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 particle size

Cement mill Wikipedia

The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet to receive wide acceptance. High-pressure roll presses
