ABSTRACT:
A method for classifying wet coal for obtaining coal charges suitable for use in a coke oven comprising classifying the wet coal directly in a cylindrical screen which rotates and revolves around an eccentric rotation shaft while blowing a high pressure gas stream to the screen to eliminate adhesion of the wet coal particles to the screen. The method enables a continuous and consistent classification of wet coals without the clogging of the screen and the dust pollution. The cokes obtained by dry distillation of the coal classified by the present method show high quality.
