Modern mill & fan instrumentation for cement plants
The constribution describes the tasks of accurately measuring gas flow through a large grinding mill such as a vertical roller mill for the production of raw meal. Besides the pure mechanical layout of the mill special attention has been given in recent years to the material and gas flow managment through the mill. The main aspects for this motivation are the product quality itself but beyond that also the flat lined operation of the mill.
Dust or no dust?
The large concern with grinding certainly is the quality of the processed product i.e. its finess at the nominal maximum throughput of the mill.
A vertical roller mill has to fullfill three basic processes which act together for achieving the best final grinding results:
