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, the branch metering scale is arranged on the branch belt and conducts metering independently, the discharging fluctuation of the first coal blending bucket only influences the metering of the first coal blending bucket and does not influence the discharging metering of other positions of the main belt, and the mutual influence of fluctuation is reduced.
Description
technical field [0001] The invention relates to the field of coking coal blending, in particular to a coal making system and process. Background technique [0002] With the current market changes, the coal shuffle in the market is becoming more and more serious. At the same time, in order to further reduce the cost of coal blending, major coking enterprises are constantly expanding procurement channels, resulting in many coal mines and unstable suppliers. In order to cope with fluctuations in raw materials in the market, major coking companies have subdivided coal types to alleviate the impact of raw material quality fluctuations. However, due to the limitation of the coal storage capacity and the design quantity of coal blending tanks, the subdivision of coal types is limited. At the same time, the quality of the same coal type varies greatly between different mines, which brings great difficulties to major coking enterprises in coal blending, and the quality of coal blen...
