Description

Technical Field

[0001] The utility model relates to the technical field of iron ore concentrate processing, in particular to a transfer device for processing and improving the quality of iron ore concentrate. Background Art

[0002] Iron ore concentrate refers to the ore powder formed after the iron ore is processed by crushing, grinding, beneficiation, etc. It is widely used in the production of pellets. After the iron ore concentrate is processed, it is generally piled in the material shed. When a customer purchases it, it is loaded from the material shed and finally shipped out.

[0003] After searching: the authorized publication number is CN219408440U, which is an iron ore concentrate transfer shed, belonging to the field of mining construction technology. It includes a steel structure plant, and multiple horizontally parallel conveying devices are arranged inside the steel structure plant. The conveying devices are arranged upwardly inclined on the conveying route, and the ends of the conveying devices are staggered in length. There is a material distribution platform between each conveying device, and inclined platforms inclined to the conveying devices are arranged on both sides of the steel structure plant.

[0004] However, the above-mentioned iron ore concentrate transfer device still has some shortcomings. Since the iron ore concentrate particles are of different sizes, they are generally loaded directly during transportation and loading. It is inconvenient to filter and screen the iron ore concentrate during loading, which makes the iron ore concentrate particles of different sizes, reducing the quality of the iron ore concentrate, and it is inconvenient to crush the iron ore concentrate with larger particles screened out again. Therefore, we propose a transfer device for processing and improving the quality of iron ore concentrate to solve the above-mentioned problems. Utility Model Content
