Abstract

The invention discloses a magnetism recovery device for magnetization of feebly magnetic ore by roasting on two pallets. The magnetism recovery device is mainly characterized by comprising a gas producing mechanism, a charging mechanism, a discharging mechanism, a frame and a hydraulic control mechanism, wherein, two pallets are symmetrically arranged on two ends of the frame, a track is arranged on the frame and the pallets move along the track. The magnetism recovery device controls a roasting reaction in a roasting chamber of feebly magnetic ores such as hematite, limonite, siderite and the like after pelletization by gas generated by the gas producing mechanism, the feebly magnetic ores are converted into strongly magnetic ores by circular and alternate operation of the two pallets, and then conventional magnetic separation process flow is utilized to obtain qualified refined iron ore for metallurgy industry. The magnetism recovery device for magnetization of the feebly magnetic ore by roasting on the two pallets has small investment, simple structure, short capital construction period, good operability and high popularity rate, and is favorable for environmental protection and easily accepted by investors especially in remote and undeveloped areas with mineral resources, and has remarkable social benefit.

Description

Technical field

[0001] The invention belongs to the technical field of beneficiation equipment, and in particular relates to a magnetic return equipment for roasting and magnetizing weakly magnetic ore with two trolleys. Background technique

[0002] my country's magnetite resources are limited, and the iron ore powder produced by magnetite is currently the main source of raw materials for the ferrous metallurgical industry. The ore source is close to exhaustion, and a large amount of ore needs to be imported. However, weakly magnetic ores such as hematite, limonite, and siderite are widely distributed in my country and have a large storage capacity. Because of its weak magnetism, the production of beneficiation is restricted. Weak magnetic ore with an iron grade of 40% is idle and wasted because magnetic separation is ineffective for it. Even if some re-election processes are adopted, the scale cannot be formed due to low output and no guarantee of quality. In order to s...
