New split oil seal for ATOX mill grinding roller cuts replacement downtime FLSmidth has designed a new splít oil seal for grinding rollers that dramatically reduces seal replacement
downtime and helps ensure higher ATOX mill availability. The new split seal can be replaced inside the mill,
without removing the grinding rollers. Conversion kits are now available for 27.5 to 52.5 ATOX raw mills. The conversion is a one-time investment: to install the conversion kit, the roller must be disassembled in the workshop.
After converting to split seals, an inner seal replacement can be done with only 15 hours of mill downtime. This simplified procedure eliminates a kiln stop and excessive loss of lubrication oil, as well as crane and workshop expenses. The new split seal requires the same frequency of replacement and maintenance as before, but is a much faster and easier operation, which requires no special tools and can be done by maintenance staff on site. An additional benefit is that the new split seals also eliminate removal of rollers when doing maintenance on air-sealing parts.
Innovative design makes seal replacement faster, easier and less expensive
