Vertical roller raw mill capacity upgrade
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.
