Abstract

The invention discloses a weak-magnetic-field dry-type magnetic separating device with an involute-arranged permanent magnet system. The weak-magnetic-field dry-type magnetic separating device comprises a body base installed at the upper ends of supports through elastic vibration pieces and vibration motors installed at the bottom of the body base. A top cover is installed above the body base, and a closed cavity is jointly formed by the body base and the top cover; a first feeding hole is formed in the center of the top cover; the closed cavity is divided by a disc support arranged in the cavity into an upper cavity body and a lower cavity body, a partition plate is arranged in the upper cavity body on the disc support, a second feeding hole is formed in the portion, bias arranged on one side of the center, of the partition plate, and a magnetic disc is arranged in the lower cavity body below the disc support, and is composed of a magnetic disc body and a plurality of pieces of permanent magnet steel arranged in an involute mode in the circumferential direction of the magnetic disc body; a discharging opening is formed in the side wall of the upper cavity body on the disc support, and a non-magnetic material baffle and a magnetic material baffle are arranged in the center of the upper plane of the disc support, wherein the tail end of the non-magnetic material baffle and the tail end of the magnetic material baffle extend to the discharging opening. By means of the weak-magnetic-field dry-type magnetic separating device, high-grade recycling of magnetic-mineral ore concentrate is achieved.

Description

technical field [0001] The invention relates to a weak magnetic field dry-type magnetic separation device with an involute arrangement permanent magnet system. Its separation characteristics have the characteristics of magnetic concentrate powder transfer and continuous separation, and it belongs to the suction type magnetic separation in mining machinery. equipment category. Its technological invention can be applied to the separation of magnetic mineral powders such as iron ore and steel slag. Background technique [0002] At present, most of the permanent magnet dry-type weak magnetic field magnetic separators are roller magnetic separators, which retain the commonly used suction-type separation characteristics. It has been proved by practice that this type of magnetic separator has low separation accuracy for minerals, especially for powder minerals, there is a defect that the loss rate is too high. How to design a new type of permanent magnetic system structure and in...
