A special RO phase magnetic separator for steel slag powder

Abstract

The invention discloses a special RO-phase magnetic separator for steel slag micro powder. The special RO-phase magnetic separator comprises a separation cavity, an RO-phase collecting cavity and a magnetic bar component, wherein the RO-phase collecting cavity is formed in one side of the separation cavity and is a half-sealed cavity; an RO-phase discharge hole is formed in the lower part of the RO-phase collecting cavity; a plurality of groups of windows are arranged between the RO-phase collecting cavity and the separation cavity; the magnetic bar component penetrates through the windows, spans between the two cavities and is used for communicating the two cavities; the magnetic bar component structurally comprises a cylinder, a magnetic system shaft, a magnetic block, a chain wheel and a bearing. When the equipment is additionally arranged on an air tube, the RO-phase in the steel slag micro powder can be effectively adsorbed and separated, and the content of inert substances in the steel slag micro powder after RO-phase separation can be reduced to within 15% from about 35% at present.

Description

technical field [0001] The invention relates to the technical field of magnetic separators, specifically a RO-phase magnetic separator equipment dedicated to the production of steel slag powder by vertical mills, and can also be used for the separation of magnetic objects in a space where wind force dispersion force and magnetic force coexist. Background technique [0002] The use of vertical mills in the production of slag powder is welcomed by the building materials industry for its low energy consumption, high efficiency, stable product quality, and integrated operations. However, there are still major problems in the application of vertical mills to the production of steel slag powder, mainly in the wear of grinding rollers. Seriously, the product quality is unstable, and the energy-saving advantage is not obvious. Among them, the main reason for the unstable product quality is that the RO phase content in the steel slag is large and the ratio is unstable, which directly...

Problems solved by technology

The RO phase can achieve monomer dissociation at a particle size of 30 to 50 microns, but at this particle size, the RO phase cannot be separated from other minerals by using traditional magnetic separation equipment, because at the particle size of the fine powder, under the strong magnetic field force Under the influence of magnetic agglomeration and electrostatic adsorption between the RO phase and other minerals in the micropowder, effective separation cannot be achieved. The steel slag micropowder is completely dry-processed, which requires the process of selecting the RO phase to disperse the RO phase and other mineral phase monomers. In the air, it is possible to achieve the separation of RO phase under the action of magnetic field force

[0003] In the vertical mill production process, the finished product after grinding is classified by the powder separator on the upper part of the vertical mill, and then the powder is driven by the wind field to the dust collector for collection and then discharged. The steel slag fine powder and air in the pipeline between the vertical mill and the dust collector are sufficiently uniform Dispersed, the traditional process is to collect the powder directly without collecting
