External magnetic barrel type magnetic separator for coarse particle mineral separation

The invention discloses an external magnetic barrel type magnetic separator for coarse particle mineral separation. The external magnetic barrel type magnetic separator comprises a stander and an adjustment platform, wherein the middle part of the adjustment platform is hinged to the stander through a main shaft; an inclination angle adjustment device is arranged between the front part of the adjustment platform and the stander; a separation barrel is supported on the adjustment platform through a supporting wheel and a catch wheel, and is connected with a driving and transmission device; an outer cover is arranged at the upper part of the separation barrel; a mineral feeding box is arranged at the front part of the separation barrel; a tailing box and a concentrate box are arranged at the rear part of the separation barrel; a washing water pipe, a mineral discharging water pipe and a concentrate flushing water pipe are arranged in the separation barrel; a magnetic system is arranged on the lateral lower part of the separation barrel; a clearance between the separation barrel and the magnetic system can be adjusted. According to the external magnetic barrel type magnetic separator for coarse particle mineral separation, the problem that coarse particle minerals extrude and collide anti-abrasion materials of a barrel body and a tank body is solved; meanwhile, the recycling rate of magnetic minerals can be effectively increased. The external magnetic barrel type magnetic separator can be used for -50mm-coarse particle magnetic mineral wet type pre-separation and waste throwing work or tailing recycling work.
