feeder, therefore, discharged exactly 100 pounds of coal for each turn of the head pulley. Ihe head pulley speed was proportional to the rate of coal fed that could be expressed as pounds of coal per minute or pounds of coal per hour, as desired. Total turns of the feeder head pulley times 100 equaled the pounds of coat fed during any given period.
Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- …

Coal fineness is a relative measurement of particle size distribution typically applied to the product leaving a pulverizer. Standardized wire mesh screens are stacked and used to shake down samples.
The main objective of a kiln feed system is to feed the kiln at any desired rate set by operator (from CCR) and to maintain it with a close degree accuracy (± 2 %) throughout the feed rate range. A fraction (5-12%) of kiln feed gets lost with preheater exhaust gas. As the chemistry of this dust is normally different from kiln feed composition ...
