In vertical roller mills, high temperatures and high particulate concentrations make maintenance a difficult challenge for operators. Especially when trying to prevent the problems that can lead to bearing failure and costly unplanned downtime.
NETZSCH Ecutec''s Atlas Vertical Roller Mills has been developed for more efficient fine grinding of soft to mediumhard materials. The Atlas is a roller airswept mill designed for continuous operation with minimum maintenance. The fundamental difference between the Atlas and other tableroller mills is the bearing arrangement for the grinding
On the other hand, the vertical roller mills (VRM) is quite a complicated and sophisticated equipment with hydraulics that controls the rollers. The material between the table and the rollers is quite thin, and it is important that the rollers and the table are not in contact with each other.
