Abstract
The invention relates to a configuration method of iron removal of a mill, especially discloses a configuration method of a mill used in an ore milling step in an ore-dressing plant and production processes of aluminum oxide and high-purity magnesia, and belongs to the configuration method of mineral processing production and production processes of the aluminum oxide and the high-purity magnesia. A material is conveyed through a belt from a mill head bin or liquid ore slurry and steel balls or steel rods returned from a branch machine device is fed into the mill and is ground to obtain ore slurry through the mill. The ore slurry is discharged through a material discharge end by means of magnetic arc and then is fed into a production process, wherein iron chips or iron pieces in the slurry is discharged through an iron discharge funnel of the magnetic arc through adsorption of the magnetic arc. In the method, most of iron in the ore slurry is discharged from the iron discharge funnel and does not enter an ore slurry process, wherein the mill is 90-95% in iron discharge rate of the material. The configuration method is less in occupied area, allows continuous operation, is free of power consumption, is beneficial to recycle and comprehensive utilization of iron, is low in investment and is reliable in technology, is free of maintenance, and is especially suitable for large-scale ore-dressing plants, aluminum oxide factories and high-purity magnesia factories.
Description
Technical field
The present invention relates to the collocation method of the ore grinding stage grinding machine in a kind of collocation method of grinding machine deironing, particularly a kind of ore dressing plant, aluminium oxide, highly-purity magnesite production process, belong to mineral processing production, aluminium oxide, highly-purity magnesite production technology collocation method.
Background technology
At present along with the development of technique of preparing, aluminum oxide technology, large-scale ore dressing plant, alumina producer, highly-purity magnesite factory get more and more, ore grinding is requisite job step in production procedure, and time in grinding production must add steel ball or rod iron, and steel ball or rod iron are grated gradually aborning and enter flow process.Except selecting iron or product need produce containing a certain amount of iron, in other productions, iron is harmful constituent in the product, or exists in mine tailing, red mud.Not only increase production cost on stream, and affect product quality, also waste resource.
