Comprehensive preparation equipment and method for weakly magnetic minerals

Abstract

The invention belongs to the technical field of mineral separation, and discloses comprehensive mineral separation equipment for weak magnetic minerals. The equipment comprises a rack, and a conveying device, a material uniformizing device, a magnetic plate, a distributing device and a spraying device which are mounted on the rack, and further comprises a magnetic conducting piece and a distributing device. The magnetic conducting piece comprises a fixing part, and the fixing part is provided with an extending structure extending upwards, and/or , the magnetic conducting part is provided with a flow guide part extending transversely, a strong magnetic part can attract the fixed part of the magnetic conducting part to the surface of an upper-layer belt, and the upper-layer belt can drive the strong magnetic part to move in the material guiding direction of an iron unloading belt. The distributing device and the material uniformizing device are sequentially installed on the rack in the material guiding direction of the iron unloading belt, the distributing device is provided with a discharging port facing the iron unloading belt, the distributing device is provided with a storage cavity for storing the magnetic conduction piece, the storage cavity communicates with the discharging port, and the magnetic conducting part can move to the surface of the upper-layer belt through the discharging port. Magnetic minerals carried up by water flow on the surface of the iron unloading belt can be effectively adsorbed and removed, so that weak magnetic minerals are screened more thoroughly.

Description

technical field [0001] The application relates to the technical field of mineral processing, in particular to a comprehensive mineral processing equipment and method for weakly magnetic minerals. Background technique [0002] The existing beneficiation equipment for weakly magnetic minerals mostly uses high-gradient flat-plate magnetic separators. High-gradient flat-plate magnetic separators are also called high-gradient strong magnetic separators. By effectively arranging thousands of strong magnets, the strong magnetic The magnetic field strength at the workpiece reaches tens of thousands of GS, which can process weak magnetic ores, such as manganese ore, hematite, limonite, specularite, etc., or it can also be used for high-level iron removal operations of non-metallic materials , can reduce the iron content in potassium feldspar, fluorite and quartz sand. However, in the existing beneficiation equipment for weakly magnetic minerals, the homogenizing device transports th...
