The EL-type pulverizer is a higher capacity pulverizer when compared to the original E-type pulverizer of the same size. E to EL conversions have significantly improved the availability, capacity, and reliability of E-type pulverizers. The EL-type pulverizer is also much less prone to coal dribble problems due to an improved bottom grinding ...
The bearings are out of the grinding cham- ber and are protected from contamina- tion. The rotor itself consists of three sec- tions: At the BOTTOM is a fan which provides the air ow for the grinding system. In addition, the fan helps to accelerate and distribute the feed material prior to the material entering the grinding chamber.
