Vertical: Also known as planetary ball mill. The mill drum has the appearance of a large jar. The drum is positioned on a platform eccentrically or rotates offcenter, known as sun wheel. The rotation of the platform causes the balls to move in a circular pattern inside their drums, increasing the grinding movement.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
1. Introduction. Highenergy ball milling is a complicated process employed in solid reactions for obtaining nanostructured materials, in powder form, with an average particle size of less than 100 nm. The planetary mill is one of highenergy ball mills, which is used for efficient and precision milling.
