Coal making system and process

The embodiment of the invention provides a coal making system and process, and relates to the field of coking coal blending. The invention aims to alleviate the problem of quality fluctuation of blended coal. The coal making system comprises a main belt, at least one first coal blending hopper, at least one branch belt and at least one branch scale, and the at least one first coal blending hopper is arranged above the main belt; the at least one branch belt is arranged between the at least one first coal blending hopper and the main belt, each branch belt corresponds to one first coal blending hopper, and the branch belts are used for conveying raw material coal blended by the first coal blending hoppers to the main belt; and at least one sub-scale is arranged on the sub-belt, and each sub-scale corresponds to one sub-belt. A coal making process is used for a coal making system. The first coal blending bucket firstly discharges materials to the branch belt and then discharges the materials to the main belt, t
