Mar 10, 2011Re: How Can I calculate new ball size and weight desing for ball mill. Hi, We have a similar mill. Pregrinding with hammer crusher and mono-chamber mill. Thisis what a proposed based on literture review i did and others agree its more and less correct. But remember it all depends on your mill feed size after pregrinding.
Mar 31, 2008Best Answer: A ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.
Milling Step-over Distance Calculator In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.
