wheel". Recently work has been conducted on an improved fan design intended to replace or retrofit the existing coal mill exhauster fan assembly within the constraints of the existing pulverizer mill. The new fan was designed to provide increased volume flowrate through the mill, increased efficiency in operation, and extended wear life.
Mechwell utilizes CFD technique and practical experience to improve the performance of coal mill. The flow behavior inside the coal mill is analyzed and various parameters affecting coal mill performance is investigated through CFD technique. CFD results can be used to examine . a range of geometry . odifications to improve the

Performance Driven Maintenance Provides A Path to Achieve Results Improved 50 mesh by adjusting classifier blades. By conducting periodic Isokinetic coal sampling pulverizer performance can be tracked so that maintenance decisions are based on the truly important measurement. Issue: 200 mesh fineness had deteriorated
Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.
Some installations have shown coal fineness improvements of more than 10% can be obtained. The High Performance Static Classifier not only replaces the original classifier cone with a more effective classifier, but with the addition of enhanced components, the segregation of coal particles within the mill housing is greatly improved.
of coal accumulated in the mill by employing a special variant of a Luenberger observer. The controller uses the rotating classi er to improve the dynamical performance of the overall system. The proposed controller is compared with a PIDtype controller with available pulverized coal
Pulverizer throughput is determined by the coal fineness desired for a given coal. However, compromising on coal fineness when your pulverizer isn''t up to snuff can increase NO x .
BW Roll Wheel™ Pulverizer Modifications Improve Performance and Reliability Hispin stationary classifier The hispin stationary classifier retrofit is for louver sections originally supplied with straight top housing pulverizers. This modification allows the same fineness with less air resistance compared to the original classifier.
