The action of additives in cement is divided into two types: Grinding aids; Quality improvers; In the world practice of cement grinding and other solids, for more than 60 years, the theory "Adsorptionrelated strength decrease of solids" has dominated, this theory is formulated in 1928 by Soviet scientist Peter Alexandrovich Rehbinder.

Regarding operations, in a ball mill, the grinding media has a higher rate of wear about the rollers and table in the VRM. In ball mills, it is essential to monitor its performance via axial testing to ascertain that the media grading is right and that there are enough topsize media to grind the mill feed materials.

Zalta grinding aids lead to gains in grinding productivity by reducing cohesion and adhesion in the ore slurry. This decreases the viscosity and/or yield stress as the slurry moves through the ball mill, improving grindability by both cascading motion and freefall ballstriking motion. Key benefits include: Improved ore throughput in grinding ...
