This method involves sifting a sample of ground material through a set of 14 test sieves, weighing the fraction on each sieve, and computing the "geometric mean particle size". This figure represents the mid point (mean) of the distribution, where 50% of the material by weight is coarser, and 50% of the material by weight is finer.

Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dâ†"V = 0.40 K√F dB = ball size (cm) F = feed size (cm)

Our industrial pin mill (also known as a universal mill or turbo mill) produces high energy impact capable of producing fine powders with an average particle size range (D50) below 100 microns, in one pass. In some instances, powders can be milled as fine as a D50 of 30 microns.

Principle of Colloidal Mill Colloidal mill works on the principle of rotor-stator. The size reduction is affected due to shearing, when the material is passed between the narrow gap of milling surfaces of rotor and stator. A rotor turns at high speeds of 3000 - 20000rpm.
