There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen's Ratcliffe-on-Soar power station has demonstrated significant fineness gain, especially at the coarse end of the particle size distribution curve, and minimal effect on mill coal throughput and operability, with greatly reduced in …

The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber. The impeller is a cage with a set of blades installed around its outer ring. It introduces a secondary classification by the collision effect in addition to the primary classification by centrifugal force [ [11], [12], [13] ].

Within a rotating-type classifier, fine particles are passed through while coarse particles are eliminated by utilizing the relative balance of centrifugal force and centripetal force produced by a blade rotating at several dozen rpm and the flow of air. MHI group offers a full line-up of pulverizer / mill systems from small to high capacity.

The first phase of this program should include a complete Mill inspection and accurate coal pipe testing which will establish baseline data. The information gained will include coal pipe balance, coal fineness, air/coal ratios, as well as the condition of the grinding components, mill throat, classifier, springs, and other components.

Let's use an MPS-89 pulverizer as an example. Most MPS-89 pulverizers are rated for about 125,000 pounds of coal per hour and this is often referred to as the mill capacity. We prefer to discuss coal throughput as one of the three major components of capacity (Hardgrove grindability and fineness are the other two). Take one version of a typical

Classifiers • The flow of coal particles through a classifier is several times the amount of coal flowing to the burners because of the large amount of coal recirculated within a pulverizer. For example, if a pulverizer is operating at 100,000 lb/hr coal feed to the burners, as much as 300,000 lb/hr or more may be flowing through the ...
MPS mill for solid fuels and other MPS mills lies in its pressure-shock resistance. Mill and classifier housing, feed unit and expansion joints are designed pressure-shock resistant. To avoid accumulations of coal dust as a source of spontaneous combustion, all surfaces in the grinding and classifying zone are vertical or inclined.
