| titleOfInvention | Drum screen for processing coal gangue |
| abstract | The invention belongs to the technical field of coal gangue processing, and particularly relates to a drum screen for coal gangue processing, which comprises a bottom frame and a fixed frame fixed on the upper surface of the bottom frame, wherein a first motor is installed on the side surface of the fixed frame, an output shaft of the first motor penetrates through the fixed frame and is fixedly connected with a first drum, a plurality of first through holes are formed in the outer side wall of the first drum, the inner part of the upper surface of the fixed frame is of a hollow structure, and a conveying pipe is fixed in the fixed frame; the cover plates for opening the first roller and the second roller pour a proper amount of coal gangue into the first roller, the first motor and the second motor are started simultaneously after the two cover plates are closed one by one through the fixing pieces, the first roller and the second roller are driven to rotate by the first motor and the second motor, the rotating directions are opposite, and the aperture of the second through hole is smaller than that of the first through hole, so that large coal gangue is thrown out to the inside of the second roller conveniently, and the purpose of screening and grading is achieved. |
