Effect of clinker grinding aids on flow of cement …
Grinding aids (GAs) are increasingly used during cement production to reduce energy consumption and/or optimize clinker factor. This stone seeks to assess the effect of such additions on variations in flow of cement pastes, including static yield stress (τ 0) and viscosity (η). Grinding tests were performed at fixed specific energy consumption (Ec) or Blaine cement fineness. For fixed Ec, tests …
Progress with grinding aids for VRMs - Cement
01.06.2018 · The adhesion forces between particles decisively affects the flowability of powders. They are proportional to the particle size: the smaller the particle, the lower the powder flowability. Grinding aids reduce the adhesion forces between particles without a negative impact on the stability of the material bed and fluidisation. In ball mills, where the grinding time is longer than in a VRM, …

A grinding aid is essentially an organic compound active in the gaseous phase which adsorbs onto the cement particle surfaces during grinding. It generates around the polarized particles a very thin monomolecular film which helps neutral-ize and reduce electrostatic forces, thus significantly decreasing the process of ce-ment agglomeration. The adsorption of the grinding aid molecules reduces ...

Preparation of polymer-based cement grinding …
During the course of grinding, grinding aid reduced the agglomeration tendency and increased the flow behavior of ground cement by diminishing the adhesion forces. Consistently lower shearing cohesion meant the grinding aid had better grinding performance. One of the methods used to represent the flowability of ground cement was its repose angle.
