Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a 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. Grinding systems are either 'open circuit' or 'closed circuit.
There are two basic types of ball grinding systems open circuit and closed circuit. In the open circuit system, the mill product has the fineness required for the next stage. In the closed-circuit system, the mill product is classified in a separator in a fine fraction that is then taken to the next step and a thick fraction that is returned.
Jan 14, 2004 If open and closed circuit experiments are compared in terms of specific energies of the products of equivalent Blaine surface area, closed circuit experiments uses energy than the open ones. Closed circuit experiments resulted in a Blaine area of 4000 cm 2 g at a specific energy consumption of 100 kW h t. However, the same surface area can be achieved at 55 kW h t for open circuit stirred mill grinding.
Cement clinker is usually ground using a 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. The drum is generally divided into two or three chambers, with different size grinding media.
