Grinding Mill widely used in metallurgy, building materials, chemicals, mining minerals in areas such as grinding materials processing. According to the fine grinding of materials and discharging materials fineness, milling machines can be divided into Raymond Mill powder machine, high pressure hanging roller mill grinding machine, high pressure Powder Mill, through centrifugal Mill overpressure trapezoid Mill, tricyclic in the six-speed milling machine types. Therefore, it is very improtant to Improve grinding efficiency of ball mill (http://www.sell-crusher.com/pro/p15.html). Here is brief introduction to the factors influencing the efficiency of ball mill:1. The influence of the ore propertiesMineral composition and physical properties have a great influence on the efficiency of the grindingtechnology. In general when coarse grained operates coarse grinding easily, and produces qualified size faster, while the fine grinding is more difficult.As with the decrease of the granularity, the weak surface of the material correspondingly reduces, which means it becomes more and more strong, so production speed of qualified particle is slower. Therefore, grindingtechnical efficiency of coarse grinding is higher than the fine grinding.2. The equipment factorsEquipment factors has certain influence on the grinding efficiency. For example, the overflow type ball mill row ore speed is slow, big density ore grain is not easy to discharge, prone to crush phenomenon. In addition, the classifier and grinding mechanism form a closed circuit , when the classification efficiency is low, it is easy to crush, so will reduce the efficiency of grinding technology.3. The operating factorsOperating efficiency factors are sure to influence the grinding technology. when sand return ratio is too large and more than the normal through capacity of grinding machine, there will be "coarse" phenomenon in the grinding.While the fact that the sand return ratio is too small or it cannot return sand, is easy to cause a crash phenomenon. And as load is too large, then "coarse" phenomenon in the grinding is serious, while load is insufficient,it has serious crushed. Therefore, grinding requires uniformity and stability feed. When the large or small amount of feed will affect the efficiency ofgrinding technology.
