Substantial gain in cement mill output with minor investment - a case study

摘要

An holistic approach is necessary for improving the productivity of any process section. In the case of ball mill operation, grinding and classification is interlinked. Once the separator efficiency drops down, then the grinding efficiency will also be affected and vice versa. By improving the efficiency of both sections simultaneously, it is possible to improve the output by 10-15 % with minor investments. This will not only improve the capacity of the plant, but also save lot of precious power for grinding. The cement mill output for this particular plant has been increased from 62 TPH to 74 TPH with specific power reduction of 2 kWh/mt.
