Abstract
The invention discloses a wind-power dry magnetic separation machine for fine ore. The wind-power dry magnetic separation machine comprises a separation tank, wherein a permanent magnetic drum is arranged in the separation tank, and comprises a rotationally-arranged drum body and a fixedly-arranged magnetic system; an ore feeding port and a dust removing port are arranged at the upper part of the separation tank; a concentrate discharging port and a tailings discharging port are arranged at the lower part of the separation tank; an air knife and a wind-power compensation device are arranged on the separation tank; the air knife is positioned by the side of the magnetic system and arranged along the axial direction of the permanent magnetic drum; an air knife holder comprises a knife holder cavity, a knife holder air inlet and a knife holder air outlet; the knife holder air outlet takes the shape of a slit; the magnetic system is arranged at a multi-magnetic-pole large wrap angle of 200-260 degrees; the drum body is made of a non-metal material; a magnetic stirring device is embedded in the drum wall of the drum body; an auxiliary ore unloading device is arranged on the outer surface of the drum body; and the highest linear velocity of the permanent magnetic drum can reach 20 m/s. By adoption of the wind-power dry magnetic separation machine disclosed by the invention, fine-graded tailings in the fine ore can be effectively separated out, thereby reducing impurities mixed up with concentrate and improving the concentrate grade. The wind-power dry magnetic separation machine is particularly suitable for the final separation of a fine-graded dry material in arid and cold regions.
Description
technical field [0001] The invention belongs to the technical field of mineral processing equipment, and in particular relates to a powder ore wind-driven dry magnetic separator. Background technique [0002] With the development and utilization of mineral resources, the selected grades are getting lower and lower. Many mineral resources in arid and cold areas that do not have mining value are gradually being valued by major mines, but water resources in arid and cold areas are limited. Therefore, the development of dry-type magnetic separation equipment, especially the development of dry-type magnetic separation equipment for final selection has become an important issue in front of mineral processing workers. [0003] In recent years, dry separation equipment including bulk dry separation machine, dry suspension magnetic separation machine and fine ore dry separation machine have been gradually applied, but based on the structural characteristics and speed of this type of ...
