In an open circuit there are no auxiliary units, such as separator and bucket elevator. This minimises the capital expenditure and maintenance requirement. The closed circuit offers process technological and energy-effectiveness advantages. Tube mills are operated with grinding media charges (balls, rods, cylpebs) of around 30 %.
Closed Circuit Ball Mill System Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.
upstream to existing cement plants with a ball mill and an air classifier in closed-circuit grinding. This pre-grinding, which partially moves the grinding load from the ball mill into the HPGR, results in savings of specific energy of around 20 per cent compared to simple closed-circuit ball mill (CCBM) grinding. 2 HPGR in a semi-finish

The cement mill,grinding systems are either open circuit or closed circuit. In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.
Raw Mill Stabilisation and Optimisation: In one cement plant, they were puzzled by the fact that while their Raw Mill 2 circuit was apparently similar in all respects to Raw Mill 1 circuit at the same location, similar operating conditions led to excessive power consumption and highly unstable operation.
