A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the m

The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.
The specific energy consumption of a ball mill is greater than a vertical roller mill (VRM) that performs the same operations by a factor of between 1.5 and 2, depending on the degree of optimization of the ball mill. Finish Grinding System. The common cement grinding systems are summarized in Figure 1 and can be divided up into three main groups:
Raw mill is mainly used in grinding raw materials and end products in cement plant. It is also suitable for various ores and other materials metallurgy, mine, chemical and construction. Besides, it has two forms of milling, one is an open form, and the other is a recycle close form equipped with powder concentrator. It is widely applied in many industries and has convenient operation.
the grinding process remains a challenging issue, due to the elevated degree of uncertainties, process non-linearity and frequent change of the set points and the respective model parameters during operation. For productivity and quality reasons, grinding is mostly performed in closed circuits: The ball cement mill (CM) is fed with raw materials.
