Classifier Pulverizer Internal

Product Introduction

CFD based investigations into optimization of coal

Sep 01, 2009 Classifier efficiency is defined as the percentages of particles reaching to pulverizer outlet after grinding. As the efficiency drops, more particles from classifier will be returned back to grinder section for regrinding which will increase the regrinding cost.

Air Classifier Mill, also called Air Classifying Mill and Dynamic Classifier Mill, represents one of the most universal milling systems available. With its combination of an impact milling rotor and an integral dynamic classifier, each with independent variable speed drives, the MJW can process a variety of materials and produce a wide range of particle size s.

Jul 01, 2015 The objective of retrofitting the Loesche dynamic classifier to their MPS pulverizer was to improve the pulverizer performance, coal throughput (by 15%) and pulverized fuel fineness whilst maintaining operating levels. 1.1 Classifier functional description The Loesche LSKS classifier is an air-flow classifier.

Dynamic classifiers were retrofitted at Central Hudson Gas & Electric's Danskammer Station to increase the capacity and improve the fineness of the existing pulverizers. The dynamic classifiers, which went on line in April 1995, replaced the existing static centrifugal and DB Riley SLS 140 internal dynamic classifier. (See Figures 1 and 2).
