To reduce energy consumption for cement ball mill
Electric consumption is the important standard to judge the grinding system. Now the grinding technology is trending to the NO Balls ( vertical roller mills or roller press grinding) and larger size equipment. With the development of cement technology, the trends of cement production total electricity consumption are as following: Over 100 kWh/t with ball mill; Around 90 kWh/t with partly materials bed grinding; Below 80 kWh/t with rollers grinding.
How to reduce the system electricity consumption of the ball mill?
1. Reduce the system electricity consumption by controlling materials sizes, moisture, grand-ability, etc.
2. By adjusting the air quantity of the ball mill
3. By scheduled maintenance and inspection of the ball mill
4. By controlling the best fineness and cement quality to reduce the electricity consumption.
Therefore the slags are taken the “ individual grinding”, the slags after grinding, with high fineness will then be mixed with the clinkers. Compared with the total mixed grinding, the capacity of the mill will obviously improve. In this way, it can not only improve the mill's effectiveness and cement activity but also avoid over-grinding, reduce the grinding electricity consumption and production cost.
