Ball Mill
Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits. Ball mills are available in both wet and dry designs, depending on the application. Ball mills have been constructed with standard final product diameters ranging from 0.074 mm to 0.4 mm in diameter.
Advantages of Ball Milling
Several of the independent variables can be reliably controlled including mill cylinder speed, media size, and of course time. Many products cannot experience elevated temperature when milling and ball mills can accommodate this by jacketing the cylinder and circulating cold water. Ball mills are available from 0.1 to 5000 gal wet or dry capacity.
