Improving Coal Pulverizer Performance and Reliability

type coal pulverizer. In this design the grinding rolls are stationary, while the ring (or bowl, as it is sometimes called) is rotated by a worm gear drive. Powerful springs force the grinding rolls against the ring, providing the pressure required to pulverize the coal. Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw

Fire Detection Methods for Coal Pulverizer Systems

The vertical spindle mill is a medium speed pulverizer and maintains a considerable amount of fuel in the mill system when operating. Coal collects on the grinding table, in the classifier, in the pyrite collection sec- tion below the grinding table, and at the fan exit for exhauster systems. These are the prime locations of fires.
