The invention provides a bidirectional reducing labyrinth type roasting machine of iron ore in the technical field of preparation equipment. The bidirectional reducing labyrinth type roasting machine is mainly characterized by comprising a heating device, a feeding device, a roasting device, a dust removal device, a cooling device and a material conveying device. Compared with a traditional rotary kiln and vertical kiln, the bidirectional reducing labyrinth type roasting machine provided by the invention has the advantages of small investment, compact structure, capability of saving reducing agent, high thermal efficiency, small installation area occupation, easy operation, energy saving, environmental protection, stable yield and the like, thereby being an ideal choice of weak magnetic ore dressing. The development and application of the bidirectional reducing labyrinth type roasting machine provided by the invention can provide a new roasting magnet return way for grading such weak magnetic ores as hematite, siderite and limonite and therefore the social and economic benefit prospects are brilliant.
Description
technical field [0001] The invention belongs to the technical field of mineral processing equipment, and in particular relates to a labyrinth magnetization roasting machine with two-way different diameters for iron ore. 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 iron content below 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 ...
