Uses of Electrodes in Drying Fine Particle Coal

Abstract

DRIERS of the fluidized bed and centrifuge types have a wide appeal in the coal industry. Such plant is used in conjunction with preparation stages to improve the yield of saleable coal in graduated sizes and to separate a range of fine coal particles. In application a type of drier is used to suit local working conditions. Factors of cost, output and discharge wastes are balanced against permissible working states. In the case of centrifuge type plant with a high output at economical cost, an effluent of fine coal particles is discharged which limits application to the coal industry.
