Abstract The calciner discharge of TiO 2 white pigments from the sulphate process is ground batchwise in a planetary ball mill, varying the energy of comminution between 0 and 5.1 times the earth's gravitational constant. Particle sizes and specific surfaces of the ground products reveal that the calciner discharge consists of aggregates of 430 nm diameter built from 160-210 nm TiO 2 crystals.

Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
