Separator tailings are returned to the mill for regrinding. The grinding plant has no dust problems as it works under negative pressure conditions, due to the pneumatic material conveyance. As there are no dust deposits (in contrast to closed circuit mills with bucket elevators), the airswept mill is especially suitable for grinding coal.

transported through railway wagons. The cement mill present in the plant is a closed circuit ball mill with two chambers. The cement ball mill has a design capacity of 150 tonnes/hour with a sepax separator. The separator can be varied around 70% to have better e ciency. The recirculation ratio of the circuit is %. The nal product
For the ball mill of the same specification, the closedcircuit process is 15~20% higher than the open circuit process; in the closed circuit operation, selecting the proper powder selection efficiency and cycle load rate is an important factor to increase the mill output. 7, Powder selection efficiency
Cement Mill. Cement clinker is usually ground using a cement ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. Grinding systems are either 'open circuit' or 'closed circuit'.
