The capacity of the vertical raw mill is often the limiting factor for clinker output – when a plant upgrades the kiln system, the raw mill frequently becomes a bottleneck. Rather than investing in an entirely new vertical mill to keep pace, there is a very limited set of possibilities in upgrading existing mill capacity in smaller steps.
Vertical Slag Mill: A vertical slag mill is used for grinding and drying water quenched slag that is generated by blast furnaces into an active material which is then added to the finished cement. Note: Feed moisture <20%, feed size <10mm, final product moisture≤0.5%, final product fineness <4200cm2/g～5000cm2/g, power consumption <33 kWh/t.
