Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and ...

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

Ball milling is another technique which was reported very recently for the production of NFC. In this method, a cellulose suspension is placed in a hollow cylindrical container, partially filled with balls (e.g., ceramic, zirconia, or metal). While the container rotates, cellulose is disintegrated by the high energy collision between the balls.

Low energy ball milling (LEBM) was employed for preliminary milling of the starting powders at 150 rpm. Subsequently, the milled powders were transferred to the high energy ball milling (HEBM) for auxiliary milling, and to ensure proper dispersion. This was performed at different milling hours (1 h, 2 h and 3 h) to further de-bundle the MWCNTs.
