For DEG, the grinding efficiency is slightly reduced by a continuous grinding aid addition, which may be explained by a lower state of stabilization due to the lower additive amount. However, the powder flowability does not changed significantly compared to that one obtained by grinding with the complete addition prior to the process.

The mill charge for each test grind consisted of a Portland cement of 95% clinker and 5% gypsum. The steel to cement ratio (S/C) was 6.5, and the temperature of grinding was 220 DEG F (104 DEG C). Results of the grinding aid tests, including comparisons with ethylene glycol (a known grinding aid) appear in Table 1. EMI4.1
Cement Grinding Aid Mechanism in VRM. Benefits of Cement Grinding Aid. CGA reduces the inter-particle attractive forces of cement which causes agglomeration of cement grains. CGA are adsorbed on the newly created surface, neutralising electrical charges and thus reducing their tendency to re-agglomerate. Hence, the cement grains show a lower ...

the industrial grinding of cement, even without the use of grinding aids. Therefore it can be assumed that the surfaces of the majority of commercial clinkers are predominantly or even completely hy - droxylated. This is also important because it as-sists the grinding, in other words water is a weak grinding aid. The chemical reaction of oxide ions
Some of the chemicals used as the grinding aids are polyol, ether & amines. Monoethanolamine (MEA), Diethanolamine (DEA), Triethanolamine (TEA), Triisopropanolamine (TIPA) are the amine based grinding aids and Ethylene glycol (EG), Diethylene glycol …
lated among others to the grinding aid dosage. Up to the maximum reasonable dosage of a specific grinding aid, the production rate increases and the separator rejects decrease. Beyond this maximum, further increased dosage results in shorter time for the cement to pass through the mill. If the mill retention time is reduced too much, the cement

AMIX TE belongs to the class of ethanolamines and is mainly used as grinding aid in the cement industry and as a performance enhancer of both cement and concrete. Ethanolamines are used as a building block, ph-neutralisation- as well as dilution-agent. Ethanolamines combine the properties of amines and alcohols in one molecule.
As can be understood, all of the grinding aids showed similar relationships and the most effective type of the grinding aid was found to be as TEA that was followed by TIPA and DEG types. The influences of the grinding aids were more pronounced specifically at less wheel speed and 3000 g/t of dosage rate.
