Classifier vane for coal mills Sure Alloy Steel Corporation

Classifier vane for coal mills . United States Patent 5957300 . Abstract: An improved vane of the type adapted for use in the classifier cage of a bowl mill type coal pulverizer. The improved vane is designed such that its lower end extends below the classifier cage inlet when the vane is mounted in the inlet.

Classification performance of model coal mill classifiers

Mar 01, 2020 The first generation of the coal mill classifier used static guide vanes to produce a swirling flow to classify the particles by centrifugal force [,,,,, ]. 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.

US4504018A Particle classifier apparatus and method with

A particle classifier apparatus and method for separating coarse particles from a mixture of particles carried in a gas stream, for preferred use in combination with a coal crushing mill. In the classifier, the gas-solids stream is passed through a plurality of internal upper angled fixed vanes for imparting a rotational motion to the particles.

INVESTIGATION ON CLASSIFICATION EFFICIENCY FOR COAL

The effect of the settings of the classifier vane angle on the coal classification efficiency was numerically investigated by several researchers 22]. The [2, 20-effect of inlet air velocity, flow vortex and turbulence on the efficiency of a scaled down model of a static-air classifier was investigated by using a two-dimensional CFD model [2].

Dynamic classifiers improve pulverizer performance and more

Jul 15, 2007 Most existing pulverizers—both the vertical-shaft and ball-mill types—come with a static classifier. Its blades reject coarse particles to produce a stream of coal particles that are mostly

CFD based investigations into optimization of coal

Sep 01, 2009 The major classification takes place in the classifier, which is located at the top of the mill housing. The air/coal mixture enters the classifier through angled vanes, which impart a swirl to the flow. Coarse particles impact on the wall, are trapped and are returned (7) to mix with the raw coal (8) on the rotating table.

US7100853B2 Deflector for coal pulverizer/classifier

A deflector disposed immediately above and outboard of a rotating vane wheel in a pulverizer/classifier is protected from wear and abrasion by side-by-side abutting high-hardness wear plates having an alloy content of approximately 15 percent chromium and three percent molybdenum by weight. The abutting edge surfaces of the wear plates are mitered.
