Abstract
The utility model discloses a dry magnetic pre-separating device for fine broken ores, which comprises a jaw crusher, a circular vibrating screen and a fine crusher, wherein a material discharging port under the circular vibrating screen is connected with a dry magnetic separator through a belt conveyer. In the dry magnetic pre-separating device, the powder ore concentrate after being subjected to dry separating treatment is conveyed to a powder ore concentrate cabin through a powder ore concentrate conveying belt, the grade of the end product ores and de-dusted dry separated ore concentrates is increased for about 42% and the tailings grade is greatly reduced; about 30% low-grade tailings can be discarded under an effect of dry magnetic separation; the recovery rate of ore concentrate magnetic iron can reach 98%; the grade of the ore concentrate can reach 42%; and the loss of the tailings magnetic iron is less and the dry separating effect is better.
Description
Technical field
The utility model relates to a kind of ore preselector, the dried magnetic preselector of ore particularly in small, broken bits.
Background technology
At present, the crushing system effect of in ore preliminary election operation, using is bad, mainly is because particle size after cracking is little; Existing processes can not satisfy use; Can't throw uselessly, cause in the present finished product ore deposit barren rock content, increase very big burden for follow-up ore screening operation up to more than 20%.
Summary of the invention
The purpose of the utility model is to provide a kind of ore in small, broken bits dried magnetic preselector, and it is simple in structure, can reduce the barren rock content in the finished product ore deposit effectively, improves beneficiating efficiency.
The purpose of the utility model is achieved in that the dried magnetic preselector of a kind of ore in small, broken bits, comprises that Hubei Province breaks machine, circular shale shaker and fine crusher, and the undersize material discharging opening of circular shale shaker is connecting dried magnetic separator through belt conveyor.
The dust concentrate that the utility model is handled through dry separation is delivered to the dust concentrate store by dust concentrate travelling belt, and concentrate grade is brought up to about 42% after finished product ore deposit and the dedusting ash dry separation, and tailings grade declines by a big margin.Dry type magnetic separation can be abandoned the low-grade mine tailing about 30%, and the concentrate Armco magnetic iron rate of recovery reaches about 98%, and concentrate grade reaches about 42%; The loss of mine tailing Armco magnetic iron is less, and the dry separation effect is better.
The utility model can reduce the barren rock content in the finished product ore deposit, can reduce 150,000 tons=4,050,000 yuan of 27 yuan of/ton * of freight charges the whole year.Simultaneously the ore grinding consumption more than 150,000 tons can be reduced, 1270.65 ten thousand yuan of economic benefits can be produced.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the syndeton sketch map of the utility model.
The specific embodiment
The dried magnetic preselector of a kind of ore in small, broken bits, as shown in Figure 1, comprise that Hubei Province breaks machine, circular shale shaker and fine crusher, the undersize material discharging opening of circular shale shaker is connecting dried magnetic separator through belt conveyor.Raw ore at first gets into the broken machine in Hubei Province and carries out fragmentation, and the discharging opening of the broken machine in Hubei Province is connecting circular shale shaker through belt conveyor.The oversize material of circular shale shaker gets into fine crusher and further processes, and the discharging opening of fine crusher is connecting the charging aperture of circular shale shaker through belt conveyor.Said circular shale shaker is two double-deck circular shale shakers.Said fine crusher is two hydro cone-crushers.
The dust concentrate that the utility model is handled through dry separation is delivered to the dust concentrate store by dust concentrate travelling belt, and concentrate grade is brought up to about 42% after finished product ore deposit and the dedusting ash dry separation, and tailings grade declines by a big margin.Dry type magnetic separation can be abandoned the low-grade mine tailing about 30%, and the concentrate Armco magnetic iron rate of recovery reaches about 98%, and concentrate grade reaches about 42%; The loss of mine tailing Armco magnetic iron is less, and the dry separation effect is better.
The dried magnetic separator of the utility model is selected the dried magnetic separator of LCG1021 fine ore for use, and the dry separation concentrate after the fragmentation is delivered to concentrate store by the concentrate belt conveyor, and the dry separation mine tailing is delivered to tailing bin by the mine tailing belt.Concentrate grade improves after the utility model dry separation, can abandon the low-grade mine tailing of part, can reduce into the ore grinding amount, reduces the ore dressing processing cost, reaches energy saving purposes.
