Cement clinker is usually ground using a ball mill. This is ... 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. Analysis of the efficiency of the .
Characteristics of open and closedcircuit grinding systems. The characteristic differences between open and closedcircuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closedcircuit is about 5% higher...
The ball mill is traditionally the basic technology in a cement plant and is a very reliable machine. It is particularly well adapted to the grinding of products at high fineness, very abrasive products and solid fuels, as well as to a wide range of minerals.
Ball mill grinding circuits are essentially multivariable systems with high interaction among process variables. Traditionally grinding circuits are controlled by detuned multiloop PI controllers that minimize the effect of interaction among the control loops.
