drying of coal in coal mill

The mill system consists of coal feeders, crusher dryers, stand-alone centrifugal static classifiers and a ball tube mill. Raw coal from the feeders is mixed with hot primary air and then fed to crusher dryers. After primary crushing and initial drying with the crushers, the crushed coal is fed into the mill get price.

    US4280418A Method of combining in the mill drying and

    A method for drying coal in a coal mill and pneumatically conveying it to a kiln for burning, with a portion of the coal-dust-laden air generated thereby being diverted to a clinker cooler adjacent the kiln in order to ignite the suspended particles and supply hot air for burning the coal. The diverted air is later recirculated back to the coal mill to help dry the coal.autogenous mill Dealer, Fote.

    Drying of the coal occurs through contact with the heated air (and surfaces) within the mill; From the fluidising zone the ground coal is lifted up inside the Mill Body. Larger particles of coal reach a terminal velocity at which gravity will pull them back on to the Grinding Table for regrinding (Elutriation);
