A dry operated, horizontal stirred media mill was used for the fine grinding of limestone and compared in open and closed circuit modes. It was found that the choice of grinding aids as well as the stirrer tip speed are crucial for the mill operation, especially in terms of the grinding efficiency and the transport behavior through the mill.An open circuit doesn't have a complete path for the current flow. A closed circuit contains a complete path for the flow of electric current. 2. In an electrical open circuit, the active energy doesn't flow from the source to the load. In an electric closed circuit, the active energy flows from the source to the load. 3.

Generally, the closed-circuit system can increase the output by 15-25% than the open-circuit system, and the product fineness can also be controlled by adjusting the classification equipment, which is more convenient. With the implementation of the national energy-saving and emission reduction policy, the ball mill grinding technology is ...When a mill is in closed circuit with a classifier, it will handle a circulating load of several times the amount of the original feed. The correct operation of a mill with proper load of balls and pulp or ore feed is determined by sound or by power meter. Normally, the sound is a rumble, whereas from a more or less empty mill there is a rattle.
