I have found that ball milling in which the mill is loaded with balls in an amount of from 50 to 60% of the mill's internal volume is particularly useful. Such milling operates at a shear rate of 40 to 100, preferably 40 to 60 Zinc dust may be used in a amount that typically occupies another 5 to 25% of the interior volume of the mill.

Ball Mill Sole Plate. This crown should be between .002″ and . 003″, per foot of length of sole plate. For example, if the sole plate is about 8′ long, the crown should be between .016″ and .024″. Ball Mill Sole Plate. After all shimming is completed, the sole plate and bases should be grouted in position.
The ball mill, an intermediate and finegrinding device, is a tumbling drum with a 40% to 50% filling of balls. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.

Semiautogenous (SAG) mills are widely used grinding equipment, but some ore with critical particle sizes cannot be effectively processed by SAG mills and turned into pebbles. This research aims to analyze and compare the properties of raw ore and pebbles from a zinc and tinbearing ore. The results show that the contents of sphalerite, cassiterite, biotite, antigorite, pyroxferroite ...

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. 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.
