INTRODUCTION The VRM is a type of grinding mill integrated with multi functions such as grinding, drying and separation, used for grinding of coal, petroleum coke and minerals.
Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that
The vertical roller mill has high energy efficiency and the installation space is smaller compared with tube mills. These days, the vertical roller mills have been widely adopted. AStructure (1) The rollers are hydraulically pressed against a disc table and the feed is ground between the rollers and the disc table.
Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits,
tional ball-mill systems, high-pressure grinding rolls in every kind of design types and their various combinations with ball mills and, of course, VRMs vertical roller mills. All of these systems treat the material to be ground differently, in that the actual grinding needed to achieve the desired character-istics varies from one to the other.
Due to the compact design and material transportation system of vertical roller mills (VRM), some important streams (total mill feed and discharge, dynamic separator feed
A more appropriate term is vertical roller mill or VRM for short. There are two different types of vertical mills Vertical roller mills. Such mills normally have integrated classifier. This means plant design is more compact / simple in comparison to ball mill / classifier circuit. On the other hand fineness is limited. Agitated vertical mills.

Three dimensional animations integrated into a process plant computer-based training program can greatly enhance trainee understanding of process equipment. This is an example of an animation used as part of an overall training program for a plant that uses an air-swept vertical roller mill. This type of mill is typically used in cement plants.
So we have vertical roller mills for grinding of cement raw material, coal and clinker, slag, whatever. In coal grinding, we also have a lot of references in the coal mills for power plants, where we have a licensing agrement with Babcock Wilcox, United States, and I dont know the actual name I think Babcock Hitachi in Germany.
This vertical mill seminar is designed to train your personnel on the overall technology, operation and maintenance of all your vertical mill systems.
