For milling speed, since previous works usually used high speed ball milling which is more than 100 rpm, the best speed for low speed ball mill is unknown. Since higher speed results in higher collision between grinding balls and powder [ 7 ], the three highest speeds of the ball mill will be used which are 100 rpm, 95 rpm, and 90 rpm.

The planetary Ball Mill has four ball grinding tanks installed on one turntable. When the turntable rotates, the tank axis makes planetary movements, the balls and samples inside the tanks are impacted strongly in high speed movement, and samples are eventually ground into powder. It has 3 types of mill methods: dry mill, wet mill and vacuum mill.

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.
