Steam coal washing processing method for easy-to-argillization gangues

The invention belongs to the field of coal dressing of steam coal and particularly relates to a steam coal washing processing method for easy-to-argillization gangues. The steam coal washing processing method for the easy-to-argillization gangues is a coal preparation process which specifically comprises the following steps: carrying out 13-mm dry screening after crushing raw coal and adopting a dense-medium shallow slot to separate coal blocks with the size of 150mm-13mm, wherein powder coal with the size which is less than 13mm is not selected; recycling coarse slime, filter-pressing fine slime and carrying out closed cycle of washing water. The steam coal washing processing method adopts the dry screening so that the argillization of the gangues is reduced to the greatest extent, and the load of a slime water system is relieved; meanwhile, a product is flexible in structure and strong in adaptability and can be adapted to possible changes of coal quality and markets in the future.
