The power consumption level of vertical roller mill is lower than that of tube (ball) mill. The feed is ground between the disc table and the rollers which are hydraulically pressed against a disc table. The remaining time of raw materials in vertical roller mill is much shorter than that in tube (ball) mill; therefore, the crushing process and mixing process became more harmonized and this contributes to quality control.
The vertical roller mill can crush materials which are too large to be fed into the tube (ball) mill. The ground materials are dried by the flue gas from the kiln.
(for 200t-RM/h capacity)
- Reduction of power consumption: 2,240,000 kWh/y
- Specific power consumption: Vertical roller mill 14-18 kWh/t-RM, Tube mill 20-26 kWh/t-RM: about 30% reduction
(for 200t-RM/h capacity)
- Production: Vertical roller mill 160-180% vs Tube mill 100%; 60-80% increase
- Installation space: smaller
- Noise level: lower
