In fine grinding of cement in a ball mill, it is sometimes impractical to grind finer in a dry state. Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to obtain the product, but it is usually more expensive, requires more energy and reduces capacity.

The negative effect of the agglomeration phenomenon on the grinding process is more apparent when cement is finer and the materials are interground. Research has shown that the extent of agglomeration depends on the specific characteristics of the materials to be ground, the fineness of the cement particles, etc. [ 6 ].

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].
