Mar 10, 2011· Re: 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.
Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where Dm = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.

and with the decreased grain size, the necessary ball size also decreases (Olejnik, 2010; 2011). For each grain size there is an optimal ball size (Trumic et. al., 2007). The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both

Ball nose tools are not designed for roughing. Use high-speed machining techniques (light DOC and high feed rates) for stable and fast cuts where greater metal removal is required. Climb milling is preferred. When plunging with Ball Nose, use pecking cycle with a maximum of .002" FPT; maximum recommended depth is 30% of ball diameter.
Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
