Addressing the Unwanted Impacts of Grinding Aids

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 water injection, and thereby improve cement quality. 2Get price
