More DetailsThe Work Index Ball Mill is used to find Grinding work index referring to the grindability index of Ores it indicate the grinding difficulty of the material. It is measured according to the principle that to calculate the grinding work index based on output of each revolution of the mill after the material is ground to a balanced state by the specified mill.

More DetailsThe test determines the Bond Ball Mill Work Index which is used with Bond''s Third Theory of Comminution to calculate net power requirements*. Various correction factors may have to be applied. W = Wi (10/√P – 10/√F) Where W = Net power consumption in kWh/t Wi = Bond work index (either Imperial or Metric units) P = The 80% passing size of the ground product in µm F = The 80% passing ...
