It works but takes a very long time to grind sand down, this is because of the size of the balls are too small. Getting larger balls will help.Nov 18, 2014 In my example it was a .1 (2.54mm) chamfer on a 1 2 (12.27mm) hole at 45 (90 included angle) with a .005 (.127mm) step, and I could still see the cusp in the simulation. Might have to do with material though. The bigger the ball mill, the smaller your cusp per step will be.

Either way, if finish matters and your mill is trammable, you’ll want to.
184.108.40.206 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 20–40 water by weight.Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less. Because of their fairly simple design, ball mills and pebble mills are less likely to need costly repairs (unlike other crushing or extraction equipment) making them an attractive option for businesses on a budget.The Hardinge mill (see Fig. 16) differs from most ball mills in that conical ends are added to the cylindrical portion of the mill. The cone at the feed end has a larger open angle than that at the opposite end. Its makers state that the large balls concentrate near the feed end of the mill where the coarsest ore collects and the smaller balls.
Plastic mill jars also run much quieter. Typically small jars have a range of ball diameters from 1-4 cm. The pebbles cost about $6 US per pound and you need about 8-10 lbs for a 1 gallon jar.
