Example Embodiment
[0033] Example 1:
[0034] Each single type of coking coal transported from the coal storage device, whose fineness meets the production requirements, is directly transported to the coal blending device 3 without crushing through the electro-hydraulic movable flap 1 for storage; the coal types whose fineness cannot meet the production requirements pass 1 The electro-hydraulic flap and the newly-built crushing device are used for crushing. The crushing fineness is strictly controlled to 80%. After crushing, it is transported to the 3 coal blending device for storage. Each single coking coal of different fineness is determined by the coal blending test in the 3 coal blending device The coal blending ratio is automatically blended into blended coal, and after being mixed by the 4 mixing device, it becomes the charged coal with a fineness of 80% that meets the production requirements and is sent to the top of the 5 coal tower for coke oven coking production.
