### Open and closed circuit dry grinding of cement mill

2004-1-14 Closed circuit grinding testsClosed circuit experiments were carried out at a constant mill stirring speed of 600 rpm. The product from the mill was conveyed to an air separator via a spiral conveyor. As an adjustable parameter the spiral's conveying capacity was used at three levels, namely 800, 1700 and 2800 g/min.

Mill capacity and the stirring speeds were the investigated parameters for the open circuit tests, whereas closed circuit tests were carried out at a constant stirring speed but variable discharge rate. Five speed levels used in the open circuit grinding tests are 200, 400, 600, 800 and 1000 rpm. The capacities were determined to obtain product Blaine surface areas in the limits between 2000 and 5000 cm 2 /g. Closed circuit

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. Gypsum is interground with the clinker in order to control the setting properties of the cement.

get price### Closed Circuit Grinding VS Open Circuit Grinding

2016-10-12 Closed circuit grinding consists of one or more mills discharging ground product to classifiers which in turn return the coarse product from the size separation back to the mill for further grinding. In this circuit, grinding efficiency is very dependent upon the size separation effected so care should be exercised in selecting the type and size of classifier used to close the system.
