Recently, the use of polycarboxylate ether/ ester (PCE), an admixture which is commonly used to improve the workability of cementitious systems, as grinding aid in the clinker mill has been reported,,,.These studies revealed that PCEs can increase grinding efficiency by reducing the agglomeration of cement particles by forming an adsorptive coatings on them.
Concavex grinding medium is an improved type of ball grinding media which offers more surface area per unit of weight, and has found extensive use in the grinding of cement clinker. The advantage of Concavex medium is its ability to increase mill capacity because of its interlocking shape and increased density per cubic foot of grinding charge.
Also, the energy cost of industrial mills decreases due to the use of isopropanolamine in cement & concrete grinding aid application, which creates lucrative opportunity for isopropanolamine in the market during the forecast period.
