Embodiment Construction

[0017] Embodiment of the present invention is described below in conjunction with accompanying drawing, embodiment does not constitute limitation of the present invention:

[0018] The low-grade magnetite closed-circuit dry separation equipment is characterized in that it includes a raw ore conveyor belt 2, a high-pressure roller mill 4 is located below the discharge part of the raw ore conveyor belt 2, and a discharge port below the high-pressure roller mill 4 Below is the belt, and below the conveyor end of the belt is the combined dry-type magnetic separator. The combined dry-type magnetic separator includes a frame, and the belts on the frame are installed by rollers. Both ends of the rollers can be rotatably installed on the frame, including the main belt. , there is a magnet between the upper and lower belt surfaces of the main belt, and the magnet is fixed by a plate on the frame. There are two rollers at both ends of the main belt, one of which is a magnetic roller, and...

Abstract

The invention relates to the field of machinery and in particular relates to closed dry separation equipment for low-grade magnetite. The equipment comprises a raw ore conveying belt, wherein a high-pressure roller mill is arranged below a discharging part of the raw ore conveying belt; a belt is arranged below a discharging hole below the high-pressure roller mill; a combined dry magnetic separator is arranged below the belt conveying end; ores separated by the combined dry magnetic separator are connected to vertical middling conveying equipment; an outlet above the middling conveying equipment is communicated to a feeding hole of the high-pressure roller mill through the belt. The equipment has the beneficial effects that through a closed cycle production process, the process route is shortened and the production and transportation costs are greatly saved; the energy is saved by 0.5-1 kilowatt hour / ton; the construction area of factory buildings is reduced; the construction of tailings ponds is reduced through a dry throwing process; large-scale tailing throwing before milling is realized, the milling grade is greatly increased, and the technical parameters of the magnetic separation section during ball-milling are radically changed; the adaptive range of a dry separation station process of the low-grade magnetite is wide.

Description

technical field [0001] The invention relates to the field of machinery, in particular to closed-circuit dry separation equipment for low-grade magnetite. Background technique [0002] Compared with the global iron ore resources, my country has a large number of low-grade iron ore mineral resources. In recent years, in order to make full use of the existing low-grade magnetite mineral resources in China to make up for the shortage of domestic iron ore resources, Domestic enterprises have been involved in the development process of low-grade magnetite mineral resources. [0003] Since the development of low-grade magnetite mineral resources firstly adopts large-scale open-pit mining and new beneficiation technology and process combination, and uses large-scale and new technology benefits to solve low-grade magnetite, it is difficult to obtain better ore with low added value. This is an important means and measure to transfer low-grade magnetite mineral resources to the develop...
