Description

Technical Field

[0001] The utility model relates to the technical field of tailings treatment, in particular to iron tailings dressing equipment. Background Art

[0002] Iron tailings refer to the waste remaining after useful minerals are extracted from iron ore. It usually contains a certain proportion of iron ore, impurities and valuable minerals that have not been fully recovered. Due to the limited resources and the need for environmental protection, the reuse and recycling of iron tailings has become increasingly important. Iron tailings beneficiation equipment is used to extract useful minerals from iron tailings.

[0003] The existing patent with publication number CN216573603U proposes an iron ore tailings beneficiation equipment. When using the iron ore tailings beneficiation equipment, iron ore is placed at the feed inlet, and then crushed in a crushing box before entering the main body of a microbubble flotation machine for screening. The distance between the crushing rollers can be adjusted to obtain iron ores of different sizes, and the second blade is used to crush the iron ore before screening, which makes it easier to screen out concentrate from the iron ore tailings.

[0004] The current patent with publication number CN216573603U proposes an iron ore tailings beneficiation equipment, which has the following problems: since the iron ore crushed by the crushing roller is directly discharged into the microbubble flotation machine, and there is still a considerable part of the iron ore that has not been completely crushed, the quality of the final screened concentrate is not high. Although other iron ore tailings beneficiation equipment on the market has the function of filtering ore materials, the large pieces of ore materials filtered out need to be manually and uniformly put back into the iron ore tailings beneficiation equipment, and ore materials of different sizes are put into the iron ore tailings beneficiation equipment together, which greatly affects the work efficiency. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an iron tailings beneficiation equipment to solve the technical problem that traditional equipment cannot filter the ore and cannot distribute it according to the size of the ore.

[0009] By adopting the above technical solution, the driving device controls the rotation of the main slag grinding plate through the rotating shaft. At this time, the mineral material entering between the main slag grinding plate and the auxiliary slag grinding plate is broken up by the rotating grinding teeth, and then falls into the gap between the grinding wheels through the contraction of the first limit block.

[0015] The utility model puts iron tailings into the material feeding port, and the driving device controls the rotation of the main slag grinding plate through the rotating shaft. At this time, the ore entering between the main slag grinding plate and the auxiliary slag grinding plate is broken by the rotating grinding teeth, and then falls into between the grinding wheels through the contraction of the first limit block. The driving device controls the relative rotation of the grinding wheels to further crush the broken ore. The crushed ore falls into the feeding port through the second limit block and is poured into the conveying pipeline through the feeding port. The ore that meets the specifications falls through the first filtering screen, and the ore that does not meet the specifications moves along the conveying pipeline through the chain controlled guide plate of the transmission device.
