Coal Vertical Roller Mill (VRM) is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grinding roller onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness.
Table 2: Comparison in cement properties and VRM operating parameters for blank, SikaGrind-455 and SikaGrind VRM-40. One of the new molecules (N° 5 SikaGrind VRM-40) was tested in an industrial VRM in comparison to a common grinding aid (See Table 2). The OPC (CEM I) made, with a surface area of 4100cm 2 /g Blaine, was of higher quality and
