Mill for cement the mill shell is divided by a diaphragm coarse grinding using big balls of up to 100 mm in diameter takes place in the first com partment the peripheral wear lining is designed as a lifting or by good mill ventilation and by injecting water

Due to the impact and friction between a large number of grinding bodies and liner a large amount of heat is generated which increases the cement temperature the temperature of the grinding material is too high to increase the temperature of the grinding cement the ventilation of the mill is not good or because of the limitation of

There is a common misunderstanding that to make a finer cement you should reduce the mill ventilation to keep the cement in the mill longer in fact this simply leads to overgrinding and increased void filling which reduces grinding efficiency and often leads to a wider particle side distribution increased separator rejects and eventual reduced mill output
