IMPROVE YOUR PULVERIZER PERFORMANCE

Pulverizer performance will deteriorate any time the machine is operated above its effective rating. The above example of switching fuels is one illustration, but a similar effect may result from switching to a fuel with lower heating value or trying to sustain higher loads with fewer pulverizers operating. Both increase the required fuel throughput. It is a certainty that LOI goes up as ...

Laboratory Sample Pulverizers - 911Metallurgist

Attempts to utilize the test mill as a replication of commercial-scale pulverization were limited because a major consideration in lignite pulverization-degree of drying in-the-mill-was not comparable. The measure of performance for a particular type of pulverizer on a lignite will best be established on commercial-size mills operating on tonnage samples. Pilot plant tests serve to establish and define relative differences
