Effect of Grinding Aids upon Ball Milling of Cement Clinker

Abstract

The effect of varying concentrations of ε-caprolactam, stearamide, acrylamide, triethanolamine and diethylene glycol upon the grinding of a cement clinker in a laboratory mill was investigated. The beneficial effect of ε-caprolactam, so far apparently an unreported additive in clinker grinding, has been realized and comparatively studied against triethanolamine and diethylene glycol which have long been successfully used in the cement industry. The characteristics of the ground products have been ascertained by nitrogen adsorption, permeability, micro-mesh dry sieving and centrifugal sedimentation techniques. Among these, nitrogen adsorption has best characterized the comminuted materials.
