Ball mill - development issues
Ball mill is pretty expensive configuration: as the ball mill cylinder speed and low (15 ~ 25 RPM), such as using ordinary motor drive, is expensive deceleration device.
Production costs are high: grinding body at the same time of impact and grinding materials, by grinding strip itself, the cylinder body parts such as lining board also be ground off, so in the cement production process, crushing assignments (raw meal preparation, cement grinding) consumed by the amount of iron is a lot of, according to the analysis, about every tons of cement production of steel consumption is about 1 kg.
Low working efficiency, such as: in the process of production of cement, electricity is used for crushing operations account for about two-thirds of all, according to statistics, every tons of cement production the power consumption of not less than 70 kilowatt hours, but this part of the electrical energy effective utilization rate is very low, according to the analysis, the input power is used for crushing materials of cement ball mill (doing useful work) accounts for only a small part of the power consumption of about 5% ~ 5%, and most of the power consumption in other aspects, mainly is transformed into heat and sound energy and disappear, this is a big waste.
Hulking: large total weight of the ball mill can be as big a few hundred tons, such one-time investment must be big.
