E to EL Conversions

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 ring and throat configuration. The E-type pulverizer can be upgraded to the EL design at one time, or it can be upgraded in stages.
