Vertical Roller Mills. Vertical Roller Mills. The term Vertical Mill denotes equipment with the following characteristics A rotating, circular grinding table that turns around a vertical shaft Spherical, cylindrical, tapered rollers that are pressed on to roller paths on the surface of the table A source of pressure on the rollers A stream of gases flowing upwards around the table, entraining ... The structure of Raymond Mill was similar with Loesche mill in many aspects.Notably, it is different from the Loesche mills cone grinding roller and the plane grinding. It used the grinding plane with 15 degree angle and cylindrical grinding roller.Grinding roller had the protective device in inspection and repair, to prevent metal to metal ...
Vertical Roller Mills. LOESCHE vertical roller mill Loesche do much more than rely solely on our unbeatable technology. Their designers are constantly coming up with new ideas and even more dependable components to reduce the already acclaimed low failure rate of our mills.

Oct 18, 2012 9 Grinding principle The feed material is reduced in size in a Loesche roller grinding mill between the rotating horizontal grinding table and the fixed grinding rollers. The axes of the tapered rollers are tilted at a 15 angle to the horizontal towards the centre of the grinding table, enabling the achievement of optimum grinding efficiency.
The principle of these Loesche grinding mills is based on a horizontal grinding table with segmented grinding plate and conical rollers which are arranged at a 15 angle to the grinding table ensuring efficient and low energy consumption grinding. The hydraulic swinging-out device for the rollers ensures a simple and fast change of grinding parts. Vertical Roller Mill State of the Art Raw Grinding. Uploaded by. zementhead.
