Water is connected to the water pipe at the rear side of the atomizing nozzle 62 and sprayed toward the coal powder from the inclined atomizing nozzle 62 to ensure uniform humidification of the coal powder.
[0037] The working principle of the integrated device for crushing and humidifying mixed coal for the experimental coke oven is described in detail below.
[0038] like Figures 1 to 5As shown, the mixed coal is put into the box body 31 from the feeding port 4, and is guided to between the two crushing rollers 52 through the guide plate 34.
