In a preferred form, the vane has a generally trapezoidal shape with a longer lower edge. The vane is additionally bent or curved over a major portion to

Fine classification with vaned rotors: at the outer edge

10/12/2004· The classifier used for the comparison is a CFS-HDS model. Results received from this classifier equipped with a Convor-wheel with constant radial velocity of the flow in the interior vane free area are compared with results from a classifier wheel designed for classification at the outer edge of the vanes. Topics of special interest: •

US6827221B1 Mill classifier Google Patents

A mill classifier, particularly a roller mill classifier, has a strip rotor and a concentrically arranged guide vane ring with flow-optimized guide vanes and flow channels for a parallel incoming and outgoing flow without constriction or with widening and a diffuser effect. The flow-optimized guide vanes with an incident flow tube with vertical rotation axis and at least one guide plate are

Classifier vane for coal mills Sure Alloy Steel Corporation

a classifier vane adapted to be mounted in the classifier cage inlet, the classifier vane having a lower end designed to extend below the level of the classifier cage inlet to form a coal-directing extension into the classifier cone when the vane is mounted in the classifier cage inlet, wherein the vane comprises an inner vane surface set at a first angle relative to the flow of coal fines

Classification of Materials and Types of Classifiers

31/10/2015· In these classifiers the separation achieved is distinct. Dry classifiers. Dry classifiers are based on the principle that separation by air fluidization. Air classification is a process of separating categories of materials by way of differences in their respective aerodynamic characteristics. The aerodynamic characteristic of a particular material is primarily a function of the size

Dynamic centrifugal gas classifier and method of

A dynamic centrifugal gas classifier according to claim 1, wherein the rotating means comprises a wheel with a plurality of vanes at a periphery thereof and the horizontal axis of rotation of the rotating means is parallel to the horizontal axis of the inner passage, the wheel and vanes being configured to propel the intermediate fraction away from the horizontal outlet means.

ACM Hosokawa Alpine

At beater tip speeds of up to 140 m/s, fineness values of d 97 = 10 µm are achieved. The product becomes entrained in the cooling, conveying and classifying air drawn through the mill by the downstream fan and is routed along the guide vanes of the vane ring. Characteristic for the ACM is the integrated dynamic classifier. The product/air mixture is distributed uniformly by the guide vane

PAPER OPEN ACCESS Study of flue-gas temperature difference

classifier vane opening and coal fineness, the output of each mill was adjusted to the level achieved when the boiler operated at full load during the experiment. The primary air velocities at the ill m outlets were maintained between 20-25 m·s-1. Three vane openings were used in this experiment: 40%, 45%, and 50%. The experimental results are shown in Table 3. Table 3. Experimental results

US Patent for Hybrid turbine classifier Patent (Patent

The second classifier cage includes a rotor which is rotatable around the axis and which defines a circumferential outlet from the cavity. The rotor has circumferentially-spaced blades directing the coal/air flow in a second flow direction opposite to the first flow direction. The vanes of the first classifier cage define a static vane angle selected to direct the coal/air flow tangentially to
