Description

Technical Field

[0001] This invention belongs to the field of grinding and relates to a grinding device for reusing dust removal tailings from artificial graphite cathodes. Background Technology

[0002] The raw materials for artificial graphite are generally crushed and ground using jaw crushers, cone crushers, and ball mills. During the crushing process, to avoid dust pollution, dust collection equipment is typically used to remove dust from the crushing area, leaving some dust residue at the filtration device. In fact, this dust residue is itself a high-purity artificial graphite raw material and can be recycled and reused.

[0003] However, the particle size of the dust collector tailings produced by different crushing processes varies. One way to reuse the dust collector tailings is to mix them with the raw materials for ball milling. However, the particle size of the dust collector tailings varies greatly, which may affect the qualification rate of products made from normal raw materials. Another method is to grind the dust collector tailings separately. However, using current ball mills to ball mill small amounts of dust collector tailings results in significant energy waste. Utility Model Content

[0004] To overcome the shortcomings of the aforementioned related technologies, this invention proposes a grinding device for the reuse of dust removal tailings from artificial graphite cathodes, which can achieve low-energy ball milling of dust removal tailings.

[0005] To achieve the above technical objectives, this invention provides a grinding device for recycling artificial graphite cathode dust removal tailings. The grinding device includes a motor, supports, and a roller. The motor is fixed relative to the ground. Two supports are arranged along a first direction and fixed relative to the ground. The roller is positioned between the two supports, with each end of the roller connected to one support corresponding to the other. One end of the roller is connected to the output shaft of the motor, and the motor drives the roller to rotate around its centerline.

[0006] The roller is a shell with a frustum structure. At least one partition plate is vertically arranged inside the roller, which divides the inside of the roller into multiple ball milling spaces. The number of ball milling spaces is one more than the number of partition plates. A closed door is provided on the side wall of the roller corresponding to each ball milling space.

[0007] Preferably, wear-resistant liners are fixed to both the inner wall of the roller and the partition plate.

[0008] Preferably, the roller is 1.5m long and includes three ball milling spaces, each ball milling space being 0.5m long.

[0009] Preferably, the roller has a maximum diameter of 1.2m and a minimum diameter of 0.5m.

[0010] Preferably, a drive sprocket is coaxially fixed on the motor output shaft. A central shaft is provided at both ends of the roller, and the roller is connected to the support via bearings. A driven sprocket is also coaxially fixed on the central shaft of the roller, and a chain is provided between the drive sprocket and the driven sprocket.

[0011] The beneficial effects of this invention are as follows:

[0012] This invention uses rollers, which can grind dust removal tailings separately. The smaller size of the rollers reduces grinding energy consumption.

[0013] The roller of this invention adopts a frustum structure and is divided into ball milling spaces by a partition plate, which can be arranged from large to small inner diameter. The ball milling space with a diameter slightly less than 1.2m can accommodate larger particles in the dust removal tailings and accelerate crushing, while the ball milling space with a diameter slightly greater than 0.5m has a higher grinding efficiency for smaller particles in the dust removal tailings.

[0021] The roller 3 is a shell with a frustum structure. At least one partition plate 4 is vertically arranged inside the roller 3. The partition plate 4 divides the inside of the roller 3 into multiple ball milling spaces 5. The number of ball milling spaces 5 is one more than the number of partition plates 4. A closed door is provided on the side wall of the roller 3 corresponding to each ball milling space 5.

[0026] The operation process of this utility model is as follows:

[0027] After the dust removal tailings are taken out from the filtration equipment, they can be classified by particle size through different types of screens. Tailings with a particle size greater than 2mm can be filled into the ball mill space 5 with the largest diameter, tailings with a particle size of 1mm to 2mm can be filled into the second ball mill space 5, and tailings with a particle size less than 1mm can be filled into the ball mill space 5 with the smallest diameter.

[0028] After the door is closed, start motor 1 to drive roller 3 to rotate at a speed of 30 r / min ~ 40 r / min.

[0029] After grinding is completed, the tailings in the ball milling space 5 can be transferred to the adjacent smaller diameter ball milling space 5 for ball milling again until the grinding particle size meets the requirements.
