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 "Adsorption-related strength decrease of solids" has dominated, this theory is formulated in 1928 by Soviet scientist Peter Alexandrovich Rehbinder.

This is the solution for grinding aids sika can offer. Grinding aids, strength enhancers and quality improvers are based on chemical products. Grinding aids work mainly by dispersing ground cement particles to avoid agglomerates, enabling an increase in production of up to 25 per cent. 1 In vertical roller mills, they can additionally be used to reduce vibrations and the amount of …

The use of grinding aids in stirred mills has also been the subject of many investigations and consequently, it was stated that the use of GA in the stirred mills increased the grinding efficiency and reduced the specific energy consumption [15], [16]. Assaad et al. [17] examined the effects of amine and glycol based GAs on cement fineness.

Raw mills usually operate at 72-74% critical speed and cement mills at 74-76%. 3.2 Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2*3.14*(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm.

A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from re-agglomeration, or re-adhering, during and after the grinding process. Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity.
