Description

Technical Field

[0001] The invention relates to the technical field of lepidolite grinding, in particular to a grinding device for lepidolite beneficiation. Background Art

[0002] Lepidolite is a kind of ore. The production of battery-grade lithium carbonate from lepidolite mainly includes three major links: lepidolite beneficiation system, mixing and roasting system, and leaching and filtration system. The lepidolite beneficiation system includes the lepidolite lithium extraction process, which requires a crushing process to crush the lepidolite into the required particle size to achieve lithium extraction.

[0003] In the actual crushing process of lithium mica, when the weather is relatively humid, the surface of the lithium mica ore is often accompanied by moisture. The common jaw crusher only squeezes and crushes the lithium mica ore through the extrusion force between the gasket and the guard plate. This causes the moist lithium mica to be more easily adhered to each other after being squeezed and split, and then some of the lithium mica particles after falling are in a sticky state, resulting in uneven distribution of the particle size of the crushed material, which has an adverse effect on the efficiency of subsequent processing procedures and product quality.

[0041] At the same time, the shaft body 1 4 will drive the intermittent gear 30 to mesh with the ring body 3 29, and then the vertical rod 1 28 above the ring body 3 29 will drive the sliding box 27 to slide on the outer wall of the piston 26 until the inner end of the sliding box 27 is in contact with the handle end of the piston 26, and the piston 26 will be pushed into the interior of the fixed cylinder 25, and then the air is inflated into the interior of the trachea 3 24, so that the airbag 23 expands to both ends, prompting the sliding part 1 801 and the sliding part 2 802 to slide away from each other, and the lithium mica above it will automatically fall down and be preliminarily crushed and ground by the crushing roller 1 2 and the crushing roller 2 3; in this, since there is a sufficient sliding distance between the sliding box 27 and the piston 26, the lithium mica to be processed located above the carrier plate 8 has enough time to be dried by the hot air, and at the same time, due to the reciprocating transmission effect of the ring body 3 29 and the intermittent gear 30, the lithium mica material is also quantitatively discharged, and the dryness and smoothness of the material grinding are guaranteed, which is conducive to the improvement of the grinding efficiency;

[0042] Furthermore, in the process of the ring body three 29 driving the magnet 34 above the vertical rod two 31 to move, the side surface of the magnet 34 will be attracted to the magnetic block 1606, and drive the magnetic block 1606 inside the fixed groove 1607 to slide downward inside it, and the magnetic block 1606 will simultaneously drive the bending rod 1605 to move inside the connecting rod 1604. As the magnetic block 1606 descends, the connecting rod 1604 will also be driven by the bending rod 1605 to descend, thereby causing the two sliders 1601 inside the ring body one 11 to descend at the same time until the sliders 1601 are The inner cavity of the ring body 11 is blocked, and the gas will enter the air pipe 1603 from the channel 1602 inside the slider 1601, and finally enter the ring body 14 and be discharged from the air outlet 15 to dry the material after preliminary grinding. Conversely, when the magnet 34 drives the magnet back to its original position, the slider 1601 is also reset, and the material on the carrier plate 8 is dried again in a timely manner. Therefore, this equipment makes rational use of hot air and realizes the drying of lithium mica in different states, which not only achieves a precise drying effect but also saves the use of resources.

[0045] In the process of sliding part 1 801 and sliding part 2 802 moving away from each other, the two will respectively drive rack 17 and rack 2 18 to mesh with gear 3 19 for transmission. This transmission process can ensure that sliding part 1 801 and sliding part 2 802 move the same distance in different directions at the same speed, so that the area where the lithium mica above the carrier plate 8 falls each time is more accurate, which is beneficial to subsequent crushing. On the other hand, sliding part 1 801 and sliding part 2 802 will also drive slide plate 1 21 and slide plate 2 22 to move away from each other inside ring body 11 at the same time. This movement process will make the hot air stored in the ring body 11 gather to the air outlet 13, so that the ring body 11, which no longer has gas flow inside, still has a small amount of hot air discharged, so that the material on the carrier plate 8 can be preheated, and the dryness of its surface is further improved.
