mill depends not only on the operating conditions, i.e. mainly the rotation speed and the filling ratio, but also on the liner itself. For this reason, the slightest improvement of the liner design becomes a significant competitive advantage. In general, the liner design depends on its material and its initial shape.

For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum’s volume so that the total volume of the drum is 50% charged. Pulp is usually 75% solid (crushed ore) and 25% water; pulp is also known as ‘ slurry ’.The operating principle of the ball mill,28· Established impact of design mills and lining forms on their productivity. Mills operating with low pulp level, have better productivity than mills with high pulp level. Particularly, productivity of mills with unloading the milled product through the grid approximately 15% higher productivity mills with center unloading the milled product.
HIGHLIGHTS OF AGICO GOLD BALL MILL. The grinding fineness and grinding time can be adjusted automatically. The cylinder body is welded by steel plates with a thickness of 1536mm. Grease is used for main bearing lubrication to avoid heavy metal pollution. The gold ball mill has the advantages of small vibration, low noise, and low labor intensity.,
