ball mill on the comminution rate and particle size reduction. Highenergy ball milling at 2000 rpm produces ultrafine talc particles with a surface area of m2/g and an estimated spherical diameter of nm. Increasing the ball size from mm to 2 mm increases the comminution rate and produces smaller talc particles.
