Therefore, the mechanical properties of the steel ball should be: First, ball mill ball has higher hardness and higher HV/E value, in order to resist the grinding of hard abrasive grain. Second, ball mill ball has enough toughness (KI) to resist impact and crack propagation. Third, ball mill steel ball has good anti fatigue ability, in order to ...
> Protect the outer shell of the mill from wear and damage > Enhance the efficiency of the grinding process > Need to be replaced regularly > Steel liners advantages – Cope with variety ores – Superior large AG/SAG, ball mills – Robust application > Rubber liners advantages — Softer ores — Less noise — Ease of replacement
Shellsupported ball mills are becoming the mills of choice over those with trunnion bearings. Depending on the size of the mill, there are two, four or six sliding shoes per bearing assembly. The expected bearing load determines whether hydrostatically or hydrodynamically lubricated bearing shoes are used. Sturdy and reliable: mill bearing ...
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
