#0183;#32;After passing through the rotor the fine coal and air mix is split into two streams via twin outlets on the top of the classifier assembly. The existing pulverised fuel pipes are connected to these outlets to allow the fine coal and air mix to be sent to the coal burners mounted on the furnace wall.
Depending on the required coal fineness, there are two types of classifier that may be selected for a vertical roller mill. The dynamic classifier, which consists of a stationary angled inlet vane assembly surrounding a rotating vane assembly or cage, is capable of producing micrometerfine pulverized coal with a narrow particle size distribution.
5 Claims, This invention relates to improvements in a cleaners and classifiers for fine coal and ]il material, and the general object of the inventic is to provide a more efficient and economic method and apparatus for effecting the class fIcation and separation of material, particular the cleaning and separation from fine coal impurities and noncombustible particles.

Hydraulic Classifiers, 17 Mar 2017 When to your a Hydraulic Classifier for CLASSIFICATION by the Dutch States mines in connection with their coalcleaning processes, is theThesis, Particle size analysis results of a typical fine coal waste sample collected from an Such classifiers include counter current classifiers, hydraulic tank classifiers,A short review on hydraulic classification and its
Two pilotscale Reflux Classifiers (600 mm #215; 600 mm crosssection) arranged in a cascading sequence were used to beneficiate fine 2 mm coal. The first Reflux Classifier performed a density separation that produced a coal product contaminated with fine highash slimes.
#0183;#32;A classifier separates coarse from fine coal by allowing the fine coal to pass and rejecting the coarse particles for regrinding. A dynamic classifier has an inner rotating cage and outer

Classifier For Fine Coal. The performance of a static coal classifier and its controlling, classifier outlets than uniform air flow distribution in the mill however, figure 23 hammer mill pulverisers used in coal fired power plants qingsheng and, the rotary classifier can meet the requirements of fineness for coal.
#0183;#32;The coal sample for the experiments was collected from the feed to West Bokaro coal washery, India. Honaker and Mondal (Honaker and Mondal, 1999) recommended a presized feed, having 3:1 size ratio between the coarsest and finest fractions, for the effective concentration in a conventional hindered bed et al. suggested a preclassified feed having size ration
#0183;#32;Reflux Classifier (RC), one of the advance gravity separator in coal and mineral processing industries, is a combination of liquid fluidized bed, autogenous dense medium and lamella settler. In the previously published literature, the feasibility of the RC for beneficiating low ash Australian coals was analyzed.
Reflux Classifier technology is gaining popularity in coal processing applications across Africa because of its ability to easily handle varying feed conditions. Traditional technology cannot accommodate these feed variations resulting in recovery losses whereas the Reflux Classifier is a lot more forgiving of solids feed rate variations.
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 coaldirecting 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
