Ball Mill Design/Power Calculation
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and …
Planetary Ball Mills
This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general. Planetary ball mills with higher energy input and a speed ratio of 1:-2.5 or even 1:-3 are mainly used for mechanochemical applications.
Ball Mills Manufacturer
Our ball mills work by putting chrome steel balls or ceramic balls into a rotating hollow cylindrical shell that rotates around its axis as friction grinds materials in an extremely fine form. As attrition size reduction is involved, the nanostructure size of the slurry of material is affected by the number and size of the balls.
