COAL CHARGE PREPARATION FOR COKING Russian patent published in 2015 - IPC C10B57/08 C10B53/08 C10L5/02 

FIELD: process engineering.

SUBSTANCE: invention may be used in by-product coke industry. Proposed method comprises batching, sorting, crushing, drying and mixing of coals. Prior to final crushing, coal charge is sized to separate fraction smaller than or equal to 6 mm and the remaining fraction of the charge is mixed with aforesaid fraction and dried to 4-6% of residual moisture content. Dusty fraction equal to or smaller than 0.5 mm is separated in drier and briquetted. Briquettes are mixed with dried charge and transferred to coke side.

EFFECT: dense coal load, higher efficiency of coking, higher yield of better CSR, CRI indices and between mechanical strength M₄₀.
