For several decades the cement industry has successfully utilized vertical roller mills (VRM) for grinding of raw materials and solid fuels. Most recently, this technology has been employed for the combination of Portland cement, blended cements and slag cements. The VRM offers several benefits compared to the ball mill in regards to operating costs and flexibility. However, the quality of the ...

The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of the particles in the bed are considerably smaller than the thickness of the bed.
Clinker grinding technology is the most energyintensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits significantly, the [.]
In many cases the roller mill has produced cements with low specific surfaces whose final strength values were superior to those of cements produced by ball roller mill...
reliable performance of both cement grinding systems. Cementos Progreso commented: "We are very satisfied with high reliability of the two cement mills, which ensures the quality and quantity of our products." In terms of throughput and residue, the cement mills are running with similar values (see Table 1). The final configuration
The cement vertical mill is grinding equipment developed on the basis of similar grinding mills, so it has many irreplaceable advantages, such as high grinding efficiency, low power consumption (2030% less power than ball mill), large drying capacity (simultaneously dry and grind materials with moisture up to 10%), the large particle size of grinding materials, simple grinding process, small ...
