In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %. It is somewhat surprising that the number of different grinding processes and mill types used by the ...
power consumption of 7% without the use of grinding aid. Including a suitable additive in such processes, the possibilities for further increase in the grinding efficiency are most likely present. In summary, conventional grinding aids are used to increase the production rate in the cement mill.
Grinding aids, strength enhancers and quality improvers are based on chemical products. Grinding aids work mainly by dispersing ground cement particles to avoid agglomerates, enabling an increase in production of up to 25 per cent. 1 In vertical roller mills, they can additionally be used to reduce vibrations and the amount of water injection, and thereby improve cement quality. 2
The consumption of energy by the cement grinding operation amounts to one third of the total electrical energy used for the production of cement. The optimization of this process would yield substantial benefits in terms of energy savings and capacity increase. Optimization of the Cement Ball Mill .
