Online ChatThe ball mill is the most common ore grinding technology today and probably more than 50 of the total world energy consumption for ore grinding is consumed in ball mills. On the other hand HPGR.
Online ChatDensity if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods. To maintain a proper balance between these two is critical. What water does is kind of provide a mode of .
Online ChatThe grinding effect of the ball mill directly affects the grinding efficiency and the output of the ball mill. In addition to considering the size of the ball mill internal structure of the ball mill product fineness requirements and other factors should also consider the characteristics of the grinding material such as grindability particle size etc.
