Bowl Classifiers. The bowl classifier incorporates a two-stage baffled-return separating action, and it consists of a straight classifier with the usual reciprocating rakes, upon which is superimposed at the lower end a shallow circular bowl with a revolving rake mechanism. The general construction of the Dorr Bowl Classifier is shown in Fig. 20.

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 …

Bowl mills are employed to pulverize the precrushed raw coal to the required fineness before it is. admitted into the boiler furnace for combustion. The. operating characteristics of bowl mills make it the. best mill available for the direct firing system. of the coal. The best features of all the pulverisers.
Bowl Classifiers. The bowl classifiers are similar to cone classifiers, except that a bowl with relatively shallow sides replaces the deep cone. The feed, in the form of slurry, enters the bowl through a centrally located pipe. The slurry in the bowl is gently agitated by rotating immersed rakes.

A shallow bowl with a concave bottom so that a liquid-solid suspension can be fed to the center; coarse particles fall to the bottom, where they are raked to a central discharge point, and liquid and fine particles overflow the edges and are collected.
Air Classifiers. RSG Inc, located in Sylacauga, Alabama U.S.A. specializes in fine powder processing technology.. RSG Inc, manufactures air classifiers, ball mills and stirred media mills for the production of fine, superfine and ultrafine powders for the mineral, mining, cement, lime, metal powder and chemical industries.
Common classifier mill variations Other common air classifier mill variations include mills with a horizontal classifier wheel, a combined classifier wheel and rotor drive, a vertical rotor, or an easy-to-clean design. Their operation is similar to that of the vertical air classifier mill, but they're configured differently. Horizontal wheel.

A bowl and rake classifier is typically used to separate coarse and fine particles of granular material temporarily suspended in water. The coarse particles settle to the bottom of the vessel and are scraped by a set of blades. The fine particles are carried over the edge of the classifier. This is how the offered rake classifier works. On the ...
