Description

technical field

[0001] The invention relates to the technical field of coal washing, in particular to a coal washing device for improving the cleaning efficiency of raw coal and facilitating the feeding and discharging of raw coal. Background technique

[0002] Coal washing is a process of operating raw coal. It is a series of processes to separate clean coal, gangue, ash, sulfur and other impurities in raw coal, and then extract the clean coal. The existing coal washing industry uses liquid floating The selection method and the dry selection method have their own advantages and disadvantages. In the existing flotation method coal washing device, some important problems are faced. For example, the flow rate of raw materials inside the feed hopper is relatively slow during feeding, which affects the entire The operating efficiency of the device, and the problem of raw coal clogging often occurs in the feeding hopper. At the same time, during the use of the existing coal washi...
