Nov 01 2003 the ballnose end mill is a special sort of toolIts ability to mill up and down the contours of complex surfaces makes it invaluable to mold shops and other makers of 3d formsAnd yet the tool is lacking in a capability one might take for granted in other cutters: the ability to machine a flat surface.

The autocharge system is primarily suitable for sag mill balls 100–150 mmAs each ball rolls through the counting chute an electro-mechanical limit switch is activated signalling the counter.
The mill out-side diameter is a function of the grind-ing process selectedAutogenous mills are the largest in diameter since the feed grinds itselfA semi-autogenous mill uses some metallic or ceramic balls to assist the grinding process and can be slightly smaller.

The steel ball size is selected so that 55 of the balls is equal or larger than 2 inches and 45 of the balls is equal or larger than 15 inches in diameterThe grinding is continued until the entire ore weight is reduced to 80 passing a screen of having quadratic apertures of 1.
This ball mill was made for grinding sand and cleaning objects like rusty boltsIt works but takes a very long time to grind sand down this is because of the size of the balls are too small.
This signature could be effectively used to optimize the milling performance by investigating this signature's relation to mill product size mill throughput make-up ball size mill speed liner profile and ball addition ratesAt the same time it can also be used to design balls and liner systems that can survive longer in the mill.
