Ball mill - Wikipedia
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. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are theGrinding Mill Design & Ball Mill Manufacturer,Feb 20, 2017· The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 20-75 mm. The biggest size is chosen when the mill is used as a primary grinding mill.Amazon: 3mm end mill,MillAMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill,,Ball Size as Initial Charge.
