Average Ball Mill Diameter

The effect of ball size on the particle size reduction has been investigated first for varying rotation speed of the container.Percent passing and size distributions of the milled al 2 o 3 powder are shown in fig.1, fig.2, respectively, as a function of particle size for varying ball size.The average particle sizes d 50 of the milled al 2 o 3 powder are shown in fig.3 as a function of.

As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
