Abstract
The utility model discloses a coal gangue sorting device, which relates to the field of sorting and comprises a rack, a feeding end is mounted on the rack, a crushing roller for crushing coal mine and gangue is mounted on the inner wall of the feeding end, and a magnetic separation conveying belt for conveying the crushed coal mine and gangue is mounted on the inner wall of the rack. A screen is arranged on the inner wall of the machine frame in a sliding mode, and a dredging assembly for dredging the screen is installed on the inner wall of the machine frame. Gangue and coal mine attached to the gangue can be uniformly crushed to the same particle size through the crushing roller at the feeding end, meanwhile, the application of the magnetic separation conveying belt realizes the rapid sorting of crushed materials, the gangue rich in magnetic substances and the coal mine with lower magnetic substance content are effectively distinguished, and the sorting efficiency is improved.
