Particle size analysis reduces cement manufacturing

Cement performance is a function of composition and fineness (particle size). Composition is controlled by manipulating both the feed to the kilns and the reaction conditions, principally temperature. Milling circuits reduce the resulting clinker to fine cement. The traditional measure for fineness is Blaine number, but increasingly cement producers are switching to laser diffraction particle

Stage 4 Finish Process Cement Production

Systems have been designed, including a de-agglomerator and separator, that will deliver material of cement fineness. However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pre-grind" process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 20-40%
