The invention discloses a beneficiation method for weathered ilmenite, and belongs to the technical field of beneficiation. According to the method, efficient recovery of the weathered ilmenite is achieved through the combined process of stage iron separation, strong magnetic pre-enrichment, multi-stage spiral chute separation, strong magnetic concentration and suspended vibration conical surface separation, and the separation indexes that the concentrate grade is 46% or above and the recovery rate is 70-78% are obtained. According to the suspended vibration conical surface concentrating machine, fine separation of titanium-containing middlings can be achieved, and compared with a conventional spiral chute and a conventional shaking table, the recovery rate of ilmenite concentrate can be increased by 5-10%, and the concentrate grade is increased by 3% or above. The method can avoid the over-grinding phenomenon, saves the cost, improves the recovery efficiency, and has a wide application prospect.

The application discloses a reverse and direct coupling flash smelting furnace and method, and belongs to the technical field of metallurgy. The furnace body comprises a direct flow reaction zone, a reverse flow reaction zone and a molten pool zone. Larger particle size furnace charges enter the reaction from the reverse flow reaction zone, and smaller particle size furnace charges enter the reaction from the direct flow reaction zone. Reducing gas is introduced from the upper part of the direct flow reaction zone, and after the gas reacts with fine particles in the direct flow downward, the gas enters the reverse flow reaction zone to exchange heat with coarse particles in the reverse flow, and finally tail gas is discharged from the upper part of the reverse flow reaction zone. Molten materials are separated into molten iron and slag layers in the bottom molten pool and discharged respectively. The method couples the reverse flow and the direct flow, integrates the advantages of the two smelting modes, avoids the shortcomings of the two smelting modes, effectively improves the metal yield and the overall energy efficiency, and reduces the raw material grinding cost and the tail gas heat loss.

The device has the effect of improving the transmission precision stability of the thread pair.

This utility model discloses a battery aluminum shell edge trimming device, belonging to the field of battery aluminum shell processing. It mainly includes a cutting assembly, which comprises a movable plate connected by four sets of support pillars. Cutting sections are installed on the four sides of the movable plate, each including a side connecting block mounted on the side of the movable plate. Each side connecting block has a U-shaped groove and a second U-shaped groove on its connecting side to the movable plate. A fixed seat is installed on the side connecting block, and a second cylinder is installed on the fixed seat. The output end of the second cylinder is connected to a connecting plate, and a third cylinder is installed on the connecting plate. The telescopic end of the third cylinder is connected to the fixed section. A U-shaped rod is installed on the fixed section, and a saw blade movably passes through the two right-angled ends of the U-shaped rod. The saw blade has inserts at both ends that form sliding pairs with the right-angled ends of the U-shaped rod. A pushing part is installed on the connecting plate. This battery aluminum shell edge trimming device, by connecting the movable plate and the cutting sections through support pillars, replaces traditional rotary cutting, controls the saw blade to achieve independent cutting, disperses stress, and reduces burrs.
