Abstract

The invention discloses a fine iron ore dressing and screening device and a screening method thereof, and belongs to the field of fine iron ore screening, the fine iron ore dressing and screening device and the screening method thereof are characterized in that a fine iron ore feeding pipe and a water inlet pipe are fixedly mounted above a mixing box, so that to-be-screened fine iron ore and water can be injected into the mixing box at the same time; water is used for mixing and wetting refined iron ore powder to be screened, so that the fluidity of the refined iron ore powder is greatly enhanced, the screening and filtering convenience of the refined iron ore powder is effectively improved, the air bag capable of being intermittently inflated and expanded is arranged in the screen drum, intermittent extrusion operation can be conducted on the mixture of the iron ore concentrate powder and the water in the screen drum, and the screening efficiency is improved. The magnetic plate is installed on the inner end wall of the upper portion of the screening box, by means of magnetic attraction, the screening efficiency of the fine iron powder can be improved, meanwhile, the reciprocating lead screw assembly drives the scraping and brushing plate to conduct left-right scraping and brushing on the inner end wall of the magnetic plate, and the adsorbed fine iron powder can rapidly fall off.

Description

technical field

[0001] The invention relates to the field of iron concentrate powder screening, in particular to an iron concentrate powder beneficiation and screening device and a screening method thereof. Background technique

[0002] Iron ore powder is the ore powder processed by iron ore through crushing, grinding, beneficiation and other operations. It is the main raw material for the preparation of pellets. It is mainly used in the powder metallurgy industry and is an important raw material in the powder metallurgy industry.

[0003] Among the existing metals, in order to improve the refining rate of iron in the powder metallurgy industry, it is an important technical means to adopt more refined iron concentrate powder. In order to purify iron concentrate powder, it is usually sieved to facilitate the removal of mineral powder Other impurities that exist inside.

[0004] When the iron concentrate powder in the prior art is screened by water, the screening operation is...

Examples

Embodiment 1

[0051] see Figure 1-10 , a kind of iron fine powder ore dressing and screening device and screening method thereof, comprising a mixing box 1, the top of the mixing box 1 is fixedly installed with an iron fine powder feeding pipe 101 and a water inlet pipe 102 extending to the inside thereof, and the iron fine powder is fed into the The inside of material pipe 101 and water inlet pipe 102 are all fixedly installed with flow valve 103, and the top of mixing box 1 is surrounded and fixed with enclosure 104 inclined from inside to outside. The inside of the fine iron powder feed pipe 101 and the water inlet pipe 102 can control the amount of the iron concentrate powder to be screened and water injected into the mixing box 1 through the iron fine powder feed pipe 101 and the water inlet pipe 102, so that More precise control is used to screen and mix iron ore concentrate powder with water, and fix the enclosure 104 inclined from the inside to the outside on the top of the mixing ...
