Ball mills scale up well and in fact improve in performed with increasing size. Ball mills are available in sizes from laboratory scale (also called milling jars) of 0.1 usg to large 5,000 gallon mills. Ball mills are available in various contact materials to accommodate contamination and wear requirements.

A trunnion seal assembly for joining a stationary inlet/outlet box of a ball tube mill to a rotational interior of the ball tube mill includes an outer ring component configured to be mounted to an outer wall of the stationary inlet/outlet box. An inner ring component is joined to the outer ring component substantially concentrically with the outer ring component.

Working principle. Fed into the mill through one or both bearing trunnions, the material is ground by impact and friction from the balls. The ground product is discharged from the mill through discharge slots provided in the mill tube, through a discharge wall or through the end trunnion.

Ball mill introduction. Structurally, each ball mill consists of a horizontal cylindrical shell, provided with renewable wearing liners and a charge of grinding medium. The drum is supported so as to rotate on its axis on hollow trunnions attached to the end walls (attached figure 1 ball mill). The diameter of the mill determines the pressure ...

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.
