When adding an amine-based grinding aid, φ GA increases with the product fineness from initially 1.08 (≈ 2000 cm 2 /g Blaine) to 1.5 (≈ 7500 cm 2 /g Blaine). In contrast to that, φ GA stays almost constant in the range of 1.2 while using a glycol-based additive. Download : Download high-res image (217KB) Download : Download full-size image

Grinding aids are organic compounds added during the grinding of clinker to prevent cement particle attraction and re-agglomeration, thus resulting in clinker and energy savings which can both lead to reduced CO 2 emissions. This paper seeks to quantify the increase in grinding mill outputs derived from the use of amine or glycol-based GA.

aids. A grinding aid is typically a polar organic liquid, such as amine, glycol, or water, that's added to a ball mill at a low level (less than 0.25 percent). This can increase the grinding rate by 20 to 100 percent compared to a system that doesn't use a grinding aid. Many theories have been postulated to explain how grinding aids improve the

The grinding process of this invention is useful in the grinding of solids containing silica or siliceous gangue. It is surprising that the use of a small amount of an alkanol amine results in more efficient grinding. It has also been found that the alkanol amine grinding aid does not detrimentally affect further processing of the treated ores.
