METHOD OF DRYING AND POST-GRINDING OF PRE-GROUND MATERIALS, IN PARTICULAR BROWN COAL OR COAL, AND APPARATUS FOR DRYING AND POST-GRINDING OF PRE-GROUND MATERIALS, IN PARTICULAR BROWN COAL OR COAL

摘要

In the drying and post-grinding method of pre-ground materials, in particular brown coal or coal, according to the invention the feed of the pre-ground material is supplied into the electromagnetic mill (1). Then the feed is ground in the electromagnetic mill (1) and pre-dried in the electromagnetic mill (1) with the pre-drying medium, supplied to the electromagnetic mill (1). Sequentially, the feed is supplied from the electromagnetic mill (1) on the vibrating conveyor (12) of the fume exhaust chamber (11) and is finally dried on a vibrating conveyor (12), wherein the feed is finally dried on a vibrating conveyor (12) comprising a ferromagnetic plate (13), on which magnets (14) are arranged, with the N poles directed towards the ferromagnetic plate (13), while at the S poles of the magnets (14) the feed transport plate (15) is arranged. The present invention also relates to the apparatus for the accomplishment of the above mentioned method.
