1) alite size, as before. 2) C2S content , as before. 3) grinding aid. Cost 0.6-1.2 €/t, usage 150-400 g/t. As the cement particle gets smaller the pores disappear and no longer become a factor. Increasing the amount of grinding aid will make the cement easier to grind. Hard burning = hard grinding.

· Here’s an exploration of the role of clinker grinding in the cement manufacturing process: Particle Size Reduction: The primary purpose of clinker grinding is to reduce the particle size of the clinker. The raw clinker typically consists of clumps or nodules with varying sizes, which are not suitable for direct use in cement production.
