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
Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.
Aug 01, 2009· (Page 1) Many branches of the chemical process industries (CPI) make use of impact comminution to process solid matter, such as minerals, foodstuffs, pharmaceutical products, and above all, products for the chemicals industry.

The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills energy efficient grinding machines. Vertimill® energy savings can range from 30% to greater than 50% compared with traditional mills, and the SMD energy savings can be far greater than 50% of ball mill energy in fine grinds.
Mill operators optimize the pattern within the mill to ensure grinding media is thrown to the "toe" of the charge to efficiently grind ore into smaller particles. Impact in a mill can harm grinding media, causing cracking or breakage, if the media is not designed and expertly manufactured for the milling environment.
