sized material is not reentrained into the air and coal stream entering the classifier. PERFORMANCE Classifier technology in the Power Industry has improved significantly with the advent of rotating classifiers. Compared to mill operation with a statictype classifier, the SLS clas sifier offers a number of performance advantages.
For nearly 100 years—ever since pulverized coal combustion was adapted for power generation—GE has been a leader in coal mill technology for the power industry. That leadership continues today with the world''s largest fleet of installed power milling equipment.
COALFIRED POWER plants use gearboxes located on the top of each coal pulverizer to drive the rotating classifier. Rotating classifiers ensure that the coal is of the appropriate size for proper ...
Efficient classification is particulary important in power station applications; a steep product particle characteristic curve ensures that optimum combustion is achieved in the boiler while keeping emission rates at a low level. Loesche dynamic classifiers can be fitted to any type of coal mill.
classifier, which consists of a cone equipped with adjustable vanes, is an option at a lower cost since it contains no moving parts. With adequate mill grinding capacity, the MPS mill equipped with SLK static classifier is capable of producing a coal fineness up to % or higher <50 mesh and 80% or

rejected from the classifier (see Figure 1). The main difference between an MPS mill for solid fuels and other MPS mills lies in its pressureshock resistance. Mill and classifier housing, feed unit and expansion joints are designed pressureshock resistant. To avoid accumulations of coal dust as a source of spontaneous combustion, all surfaces in
Mar 31, 1987· The drawing shows a partial section of a rollerandbowl mill for a pulverizedcoal furnace, in the mill housing 1 of which the grinding part 2 is accommodated with the truncatedconeshaped classifier 3, arranged above the latter, and the coaxial coal feeder tube 4.
Welcome to Classifier Milling Systems. Classifier mills are particularly complex structures. At Classifier Milling Systems, our selection of flexible powder processing equipment and expertise regarding classifier mills is incomparable. Our team''s commitment to the customer sets a higher standard in the industry.
Particles rejected by the classifier are continuously recycled back to the impactors for further reduction. CMS''s Air Swept Classifier System has been uniquely designed to produce a narrow particle size distribution. While the mill is in operation, the speed of the classifier can be changed to compensate for rises in differential pressure losses.
Coal flow balancing ( by adjustment of values on PF pipes); Check / calibration of coal flow obtained from volumetric or gravimetric coal feeder to mill and check on mill capacity limits (and assessment of reason for limits); Mill power consumption (per unit of coal throughput) including as a check on classifier recirculation rates;
