8.3.2.2 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.

Through an innovative manufacturing process we've produced a ball with greater impact resistance and reduced spalling compared to the standard SAG ball, ready to perform in the highest impact SAG milling environments. PRODUCT SPECIFICATIONS. SIZE: SAG milling grinding media are available in sizes from 4.0" to 6.5" or 105 mm to 160 mm.
This reduces the overall weight of the liner assembly. Loads on shells, heads, and bearings will be reduced. p PolyStl™ liners last longer than steel liners in many applications, thereby reducing the cost per tonne of ore processed. p The sound pressure levels of a PolyStl™ lined mill are lower than that of a steel lined mill.
If your SAG is fitted with a Variable Speed Drive (VSD), this is easily compensated for with a small speed change. Motor torque should not really change, mill weight will of course increase, but as the mill was …
DynaSteel® ensures complete protection from excessive wear on the mill lining and delivers maximum grinding efficiency. The lifter face angle remains constant throughout the life of the lining. DynaSteel® has proven to be successful in demanding applications, especially in primary grinding mills. The challenges faced by conventional steel ...
