1. Introduction. The history of grinding aids in dry fine grinding processes starts in the late 1930s with the application of the first commercial grinding aids in the cement industry [].Since that time, the importance of grinding aids in industrial dry fine grinding processes has strongly increased; so did the number of scientific papers dealing with this topic.

triethanol amine are used as grinding aids and strength enhancer for OPC. They are provided from Aldrich-sigma. Preparation of dry mixes During the grinding of OPC clinker in lab ball mill, the grinding aids are added with the ratios 0, 0.03, 0.04 and 0.05 wt. % of the clinker with gypsum. A constant 10% of gypsum by weight of clinker

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.

Grinding aids are mostly organic compounds that are added to the clinker in the cement milling process. Their main purposes are to reduce the energy required to grinding process the clinker into a given blain and therefore increase the efficiency of the cement mill. Grinding aids have been used for more than 50 years and the most common grinding aids are diethylene glycol, triethanol amine ...

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
