flyash feeding to cement mill separator

Blended Cement - an overview | ScienceDirect Topics

The principal difference is the point of feeding fly ash in VRM systems. VRMs have built-in high-efficiency separators. Fly ash, being a naturally fine product, can bypass the mill and be fed to the separator at the mill. The roller press and ball mill combination is also being adopted in a variety of ways to make cement. 1.14
