Its main function is to grind cement clinker (and gelling agent, performance adjustment material, etc.) to appropriate particle size (represented by fineness, specific surface area) to form certain granular level, increase the water area and accelerate the hydration rate of cement paste, so as to meet the condensation and hardening requirements.

Cement grinding Vertical roller mills versus ball mills

This is achieved in a cement raw mill. The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm. The measure of fineness usually used is the "specific surface area", which is the total particle surface area ...
