The invention relates to the use of methyldiethanolamine as agrinding aidfor cement, and in particular its use as a strength enhancinggrinding aidfor cement. The compressive strength may be enhanced by the methyldiethanolamine at both at an early stage (1and/or 3 days from the start of hydration) and at a late stage (7 and/or 28 days from the start of hydration).

Although many studies have been conducted to date to investigate the effects of grinding aids (GAs), none of them specifically examined the effect of GAs on transportation rate of material inside the ball mill. In this study, the effects of GA on transportation rate of the ground material inside the cement ball mill and the effects of this change on the whole grinding circuit were investigated.

In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition.
