Abstract:

Bearings seat were located inside the chamber and on both sides of  Φ1 220 reversing valve of Maerz lime kiln.Bearing seals could be easily burned out by hot gas and high concentration dust during the producing process,which could cause bearing failure and take too much time to replace the bearing and lead a great impact on production.After analyzing the reversing valve and improving its construction,bearing blocks are setted outside of chamber,which effectively avoids the accident of bearing failure etc.and ensures stable production.
