How to Make a Ball Mill: 12 Steps (with Pictures) - wikiHow

Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.

Lignin - an overview | ScienceDirect Topics

M.T. Holtzapple, in Encyclopedia of Food Sciences and Nutrition (Second Edition), 2003 Lignin Isolation. Milled wood lignin is isolated from plants by breaking the lignin–carbohydrate complex through extensive ball milling or vibratory milling for 2–28 days. The lignin is extracted by dioxane/water (9:1, v/v) with subsequent purifications in solvents.

Rod mills, how they function - Mine Engineer

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
