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

One cement mill system (CM1) produced approximately 65 mt/h of cement and the second cement mill system (CM2) produced approximately 20 mt/h of cement. CM1 is a ball mill in closed circuit with a high efficiency classifier and a pregrinding system. CM2 is an open circuit ball mill system. The product from CM1 and CM2 are 4700 and 4100 Blaine respectively. To satisfy the strength requirements of the …
Learn MoreMill 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. …
