Fine Grinding Ore Mills

A method of grinding a mineral-containing ore, which includes grinding the mineral-containing ore in a primary milling process and thereafter fine grinding the mineral-containing ore in a secondary ball-mill. A composite grinding medium comprising a mixture of steel balls and pebbles is used in the secondary ball-mill. The pebbles have an average size which is relatively smaller than the ...

In stirred-medium mills, the stirrers set the contents of the mixing chamber in motion, causing intensive collisions between the grinding medium and the ore particles and between the ore particles themselves. The grinding action is by attrition and abrasion, in which very fine particles are chipped from the surfaces of larger particles, rather than impact breakage.

Three features of stirred mills that transform the economics of fine grinding are : - the high intensity attrition grinding environment - the ability to use fine grained media (eg 1 mm) to suit to the fine grained feed - the ability to use cheap natural products (local sand, slag, ore) as grinding media
