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 Continuous Ring Mill with built-in Rotating Sample Divider CRM RSD combines pulverising and splitting into one single process resulting in increased productivity. The Continuous Ring Mill is used for coarse pulverising of large samples for mineral separation such as Zircon dating preparing samples for on-stream analysis dry or slurries.
The present invention relates to a mill inert apparatus for a coal pulverizer in which an inert medium is introduced into a coal pulverizer for pulverizing coal to lower an oxygen concentration in the coal pulverizer whereby the explosion of the pulverized coal is prevented and it also relates to a method for preventing the explosion. 2.
than normal either when initating coal feed on mill start-up stopping coal feed on shutdown or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer the coal air mixture in the system becomes leaner and the coal dust will be ground to a more uniformly fine size and dried to a greater extent.
The crushed coal is fed to the drier from the raw coal bunker by gravity. The drying of coal is effected either by using hot gases preheated air or bled steam. The dried coal is fed to the pulverizer with the help of feeder. The pulverized coal is carried from the pulverizer mill with the help of air and it is separated in the cyclone separator.
