Abstract

The invention provides a high-efficiency drum type magnetic separator and belongs to the technical field of magnetic separation equipment, which is used for efficient mineral separation. According to the technical scheme of the invention, the front end and the rear end of a drum are respectively supported by a rolling bearing and a carrying roller. The drum is driven to rotate by a speed reducer and a motor. A mineral feeding tube and a mineral-discharge water tube extend into the body of the drum through the front end of the drum. A mineral concentrating bucket is arranged below the mineral-discharge water tube. The discharge end of the mineral concentrating bucket extends out of the rear end of the body of the drum. A tailings collecting tank is arranged below the rear end of the drum. A magnetic system is fixedly arranged below the external side of the drum. The magnetic system is opposite to the outer wall of the drum. According to the invention, the magnetic system is arranged outside the drum, so that the action area and the action strength of the magnetic system are improved. Therefore, the sorting area is greatly increased. Meanwhile, the concentrate recovery rate is conveniently improved, and the tailings grade is conveniently controlled. Based on the external arrangement of the magnetic system, the supporting problem of the magnetic system is solved. In this way, the drum type magnetic separator can be made to be ultra-large scale, and the processing capacity of each single high-efficiency drum type magnetic separator on ores is greatly improved. The need of the large-scale production can be met.
