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.Henan Mining Machinery and Equipment Manufacturer - .rolltex electro discharge texturing of mill rolls. rolltex. browse online brochure. rolltex edt electro discharge texturing. world leading technology for texturing ...
