Energy efficiency in clinker production. The cover story captures the journey of an ageold system of grinding to the present one. It covers from mill internals to the use of grinding aids. A cement clinker is usually ground using a ball mill. This hardware is generally divided into two or three chambers, with different size of grinding media.
As part of its green cement plant project, thyssenkrupp has expanded its product range with the polysius® booster mill. While one cement manufacturer has already integrated the mill into his existing grinding circuit, several others have tested the mill since August 2020 and are checking results in terms of specific business cases.
Because 60% of cement plants still use ball mills as the main grinder, the grinding process can be improved by substituting ball mills with more energy efficient mills, ... performance of the new grinding system is still bounded by the hardness of raw material used. Improving refractories is bounded by types of raw materials and fuels used and ...

Grinding systems in cement production make up approximately 85 to 90 percent of total plant electrical energy consumption. As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to. maximise productivity and minimise operating costs.
VRM proposal for new large capacity cement plants Recently, with increasing cement plant capacity, vertical mills are being used not only for raw material and coal grinding, but also for cement grinding. Figure 3 shows a typical VRM arrangement for a new cement plant. The larger cement plant capacity becomes, the larger
