BallNose End Mills. Ballnose end mills have a domeshaped tip. These excel at highdetail contours like relief artwork or mold and die making, but have what is known as "scalloping." Since the tip of the end mill is round, having a perfectly flat surface is a challenging feat and will take many more passes than a simple fishtail to smooth ...

Coal Slag Coal slag is byproduct of coalburning power plants, considered a "green" abrasive because it would otherwise be disposed of as waste. It is a relatively cheap, low dusting abrasive with low free silica, but is considered a dirty abrasive and not widely used in wet abrasive blasting because the high amount of "fines" (fine particles) mud up on the surface.

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.
