Permanent-magnet cylindrical cage type high-gradient magnetic separator with high processing capacity

Abstract

The invention discloses a permanent-magnet cylindrical cage type high-gradient magnetic separator with high processing capacity. A separating cylinder (2) is a cylindrical cage which is a rotary body and is filled with magnetic matrices (4); two ends of the cylindrical cage are supported on a hollow support shaft (3) through bearings; a magnetic system is a permanent-magnet lattice uniform magnetic field system formed by an upper magnetic system and a lower magnetic system, the upper magnetic system is arranged in the cavity of the cylindrical cage and suspended on the hollow support shaft (3), the lower magnetic system is installed outside the cylindrical cage, the hollow support shaft (3) is a non-rotary body, one end of the hollow support shaft (3) is used as an axes feeding port (12),the middle of the hollow support shaft (3) is provided with a baffle plate, and one side of the baffle plate of the hollow support shaft is provided with a separating and feeding port close to the feeding port (12), the other side of the baffle plate of the hollow support shaft is provided with a concentrate feeding port (14), and the other end of the hollow support shaft (3) is used as a concentrate discharging port (13). The permanent-magnet cylindrical cage type high-gradient magnetic separator has the advantages of easiness for maximization, convenience for design and production, low energy consumption, reasonable magnetic distribution, uniform background magnetic field working region as well as high processing capacity and stable separation indexes under limited tonnage and volume.

Description

technical field [0001] The present invention relates to a permanent magnet cage type high-gradient magnetic separator, in particular to a drum cage containing a suspended magnetic accumulation medium and its driving mechanism, a magnetic system and a magnetic field adjustment device, a tank body, a pulsation mechanism, a frame, etc. A high-capacity permanent magnet cylinder-cage high-gradient magnetic separator is mainly used for wet magnetic separation of weakly magnetic fine-grained minerals. Background technique [0002] After years of mining and utilization of iron ore resources in my country, high-quality magnetite ore is nearly exhausted, while other iron ore resources, such as: hematite, limonite, siderite, specularite, etc., are difficult to sort and cost High, the mining utilization rate is not high. At present, the mature processes for selecting magnetic iron minerals include gravity separation-strong magnetic separation-flotation, roasting-magnetic separation and ...
