Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.


Minimizing the use of plastic in the mill, particularly where it has a chance of getting into the fibre supply. Using `pulp-safe' plastics where plastics are required. Generally, pulp-safe plastic is considered to have a melting point >160°C and a specific gravity >1.0.

Recommended media charge : 70 - 75% of mill's useful vol. Calculation of media load : Example : Attritor mill net volume is 50 Ltr charging with Ø 8 mm balls. 70% of mill's vol = 35 Ltr x 1.6 kg/Ltr (bulk density of Steatite media). That is 56 kg of Steatite grinding media is required for 50 Ltr capacity attritor mill.

Grinding media density. The range of specific gravity for commercially available grinding media runs from 1.0 for plastics to 15 for tungsten carbide. It makes sense that you wouldn't select a very light grinding bead for a highly viscous system or a very dense grinding bead for a low-solids aqueous suspension.

Effect of Water & Density on Grinding Mill

As you increase the volume of the through put, the time that the ore has to react to the grinding media is lessened. As you add ore to the mill you are also adding WATER and changing density which affects the slurry rheology and workings of the grinding action inside that mill. This water is one- of the main controls that you have over your grind.

Density of pelleted feed - Engormix

Typically the bulk density of UP/C® pelleted feeds is about 550 to 650 grams per liter. The raw material affects the finished product density to the greatest extent. High fiber diets tend to have the lowest raw material densities; therefore, one can not expect to achieve the same finished product density as a feed high in protein or starch.
