Abstract

The invention discloses a manufacturing technique and manufacturing equipment of silicon iron powder for secondary aluminum and diamond flotation. The steps of raw material pretreatment, smelting, water atomization, drying and screening and the production equipment are included, a vacuum atomization system of the production equipment comprises an atomization furnace, a vacuum induction furnace, water spraying equipment and discharging equipment arranged at the lower end of the atomization furnace, and a heating device is arranged inside the atomization furnace; the water spraying device comprises a water tank, a first high pressure spraying nozzle and a second high pressure spraying nozzle, the first high pressure spraying nozzle and the second high pressure spraying nozzle are connected to the water tank, and one end of the first high pressure spraying nozzle extends into the atomization furnace; and the discharging equipment comprises a filtering net and a waste water collecting groove, and powder prepared after atomization is subjected to initial water removal. By means of the manufacturing technique and the manufacturing equipment of the silicon iron powder for secondary aluminum and diamond flotation, waste resources and powder are sufficiently used as hollow spheres, so that the density is low, the iron amount is high, the magnetism rate is high, and the mineral separation efficiency is improved; and the production finished product rate of the production equipment is high.

Description

technical field [0001] The invention belongs to the technical field of powder metallurgy, and in particular relates to a production process and manufacturing equipment for ferrosilicon powder used for secondary aluminum and diamond floating. Background technique [0002] Mineral resources need to be beneficiated after mining. The currently used beneficiation methods include magnetic separation, electric separation, gravity separation, flotation and so on. Dense media beneficiation uses a medium with a density greater than water as the beneficiation method. This kind of beneficiation method needs to use a large amount of beneficiation media. In the beneficiation medium, ferrosilicon powder is mainly used as the weighting material. [0003] In the field of ferrosilicon powder preparation, the ferrosilicon powder prepared by the existing production technology has a high density and low magnetic rate, which leads to low beneficiation efficiency during ore dressing; It is easy t...
