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 ...
Pulverizer mills act as size reduction equipment. They reduce coarse materials like coal and gypsum at high speeds to tiny granules for a variety of applications. Centrifugal force powers the pulverizers to grind feed materials down to the required size. Pulverizing is typically defined as reducing to 25 mesh and beyond, but Williams machines ...
The four most common types of coal pulverizers are: Ball-Tube Mills This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal,crushing and pulverizing it.

A packing for preventing leakage of air between a rotating yoke of a coal pulverizer and an annular seal surrounding an extension of the yoke. The packing is a ring of compressible graphite. A band encircles the graphite ring and clamps it tightly against the yoke extension and against the seal.
Pulverizers / Mills. Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW. B&W's pulverizers, found at power stations throughout the world.
Pulverizer manufacturers provide pulverizers that can be used on many different material types, including brick, shale, coal, concrete, limestone, wood, and even plastic materials. Because there are so many uses of pulverizers, and because they are used to process such a wide range of materials, an equally wide range of pulverizer ...
Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill "puffs". Explosions in a pulverized coal system are normally called "puffs.". A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.
