[0002] Magnetic separation and transportation of magnetite concentrate is a crucial step in mining and mineral processing. The separation and transportation of magnetite concentrate is a critical step in the mining and smelting of magnetite. Magnetic separation utilizes differences in the magnetic properties of minerals to separate and transport them. During the magnetic separation and discharge process, the ore is discharged from one side of the magnetic separation equipment. Improperly designed discharge piping can easily cause the magnetite concentrate to fall, making it difficult to recollect. This can affect the normal operation of the production line and reduce production efficiency. Therefore, we propose a magnetic separation and transportation device for magnetite concentrate to reduce the risk of leakage and blockage, ensuring the proper operation of the conveying process.

[0018] Working principle: When magnetic separation is carried out on magnetite concentrate, the drum magnetic separator 1 is a dry magnetic separation. A feeding port is provided on one side of the drum magnetic separator 1. The crushed magnetite concentrate is first poured into the inner cavity of the drum magnetic separator 1. The magnetite concentrate will enter the magnetic system below the round roller of the drum magnetic separator 1. The magnetite concentrate with no magnetism or weak magnetism will remain at the bottom of the drum magnetic separator 1. The magnetite concentrate will be adsorbed on the surface of the round roller due to its own magnetic particles. It will rotate with the round roller to the weak magnetic field at the edge of the magnetic system, and then fall off through the scraper structure 7. The scraper structure 8 is connected to the baffle 82 through the side rod 81. A scraper 83 is provided between the baffles 82. The scraper 83 is in contact with the round roller. At the same time, the baffles 82 on both sides have a certain curvature. The baffle 82 can cooperate with the gap between the round rollers to prevent the magnetite concentrate on both sides from falling out during rotation. Through the limiting and scraping of the scraper structure 8, the magnetite concentrate falls into the permanent magnet drum magnetic separator The magnetite concentrate is collected in the side hopper 2 on one side of the separator 1. A first circular hole plate 3 and a second circular hole plate 4 are respectively provided on both sides of the side hopper 2 and the drum magnetic separator 1. The first circular hole plate 3 and the second circular hole plate 4 are flange-connected by bolts through the circular holes provided on the circular holes on both sides, providing a disassembly function for the side hopper 2. At the same time, a roller 5 driven by a first motor 6 is provided inside the side hopper 2. The rotation avoids blockage of the magnetite concentrate and facilitates the unloading work. The magnetite concentrate is transported through a conveying structure 7 provided at the bottom. The conveying structure 7 forms a complete conveyor belt through a conveyor belt frame 71 and a skirt conveyor belt 73, which is driven by a second motor 74. Due to the setting of the skirt conveyor belt 73, there are arc-shaped protrusions on both sides, which can limit the magnetite concentrate to avoid leakage of the magnetite concentrate during transportation. The overall magnetic separation and transportation work is completed through the cooperation of the conveying structure 7 and the scraper structure 8.
