THE MODE OF BALL MILL OPERATION

This is the most common mode used during operation of rod mills, ball mills with central unloading and pipe mills in the case of wet and dry grinding of non-corrosive materials. Mixed operating mode is illustrated in the figure b, where the dotted line shows the position of the grinding balls in flight along the trajectory and solid lines – balls moving by rolling.Get price

Ball Mills

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.Get price
