Each ore particle has to pass through 8 consective grinding chambers (the grinding discs), ensuring no short circuiting. Particles have to escape the high centripetal forces of the product separator (20m/s tip speed) before leaving the mill (this is why IsaMills™ do not need to be closed circuited with cyclones).

The laser diffraction particle size of the ground talc using 2 mm and 1 mm balls showed similar particle size distribution when compared with the case of using 0.1 mm balls. In both series, the intensity of the sub-microscale group was larger when using 2 mm and 1 mm balls than when using 0.1 mm balls, which indicates a larger particle size
