What Affect the Grinding Efficiency of Ball Mill

Influenced by the humidity of ores and stones, there will be a layer of thin material forming on the surface of the ores and scaleboard. Therefore, in the aspect of energy consumption, the dry ball mill will waste about 25% energy comparing with wet ball mill. In addition, the dry ball mill has stricter requirements on the moisture content of raw ores. When the water content in the ores is high, the discharging ore will reduce to some degree. In this case, in order to reduce the content of moisture, it has to add some hot air facilities. And then, the dry ball mill will need more investment cost and production cost. On the contrary, the wet ball mill can deal with ores with high water content and high clay with a high efficiency.For materials, if the materials have strong fragility, they are easy to grind and then the capacity will be high and vice versa. On the other hand, if the feeding materials have large granularity which need more steel ball in the grinding cavity, it will influence the grinding efficiency directly. Therefore, the feeding granularity should be smaller so as to improve the production capacity and reduce the electricity consumption.In other aspect, the structure of ball mill will also influence the capacity of ball mill. Firstly, the draw ratio of ball mill is decided by the production method, ball mill with different production system should equip with different draw ratio in order to guarantee the fineness and capacity of final products. For instance, The ball mill usually has 2 to 4 bins and the draw ratio is larger, there are more bins.Moreover, the type, specification and filling rate of grinding body will also influence the grinding efficiency. Therefore, it had better choose correctly and reasonably. The scaleboard’s surface shape of ball mill has strong effect on the capacity because it can change the lifting height of grinding body. So it is important to choose a suitable scaleboard.grinding mill:...
