Vertical Roller Mill Play An Important Role In Cement Industry

Vertical roller mills create a particle size distribution with a sharper cut in comparison to cement milled in a traditional ball mill. That is, the particle size distribution is in a narrower band.

With the continual increasing demand for portland cement and constant pressure for reduced energy consumption, Cement clinker processing plant are exploring a wide variety of cost-saving manufacturing options. One option is vertical roller mill technology for finish grinding.

Traditionally, Cement manufacturing plant used cement ball mills to grind clinker and gypsum into cement,Since the 1980's, cement processing plants are increasingly looking to vertical roller mill technology for their finish grinding needs. Vertical roller mills present a compact and efficient grinding method. Clinker and gypsum is ground on a rotating table that passes under large rollers. Material is forced off the table by centrifugal force, where it is then swept up into an airstream to a classifier immediately above. Just as with a ball mill, material that is too coarse is returned to the table for additional grinding while material that is fine enough is collected as product. The compact design of a vertical roller mill allows it to dry, grind, and classify, all within one piece of equipment and all in a relatively compact space.

Vertical roller mills create a particle size distribution with a sharper cut in comparison to cement milled in a traditional ball mill. That is, the particle size distribution is in a narrower band. This sharper cut means potentially less variability in product consistency and, hence, more predictable results in product performance.By changing various vertical roller mill operating parameters, significant adjustments in the particle size distribution, retention time, and fineness of the finished cement can be achieved. This can help with plant operations as production is switched between different cement types.
