Embodiment 1
[0024] The BL-600 double-head spiral chute used in the laboratory is taken as the research object, and its pitch is 360mm.
[0025] The method for improving the recovery rate of magnetic minerals in the spiral chute is as follows:
[0026] 1. First, rinse and dry the spiral chute used in production;
[0027] 2. Draw 4 circles of spiral shrinking lines on the surface of the cleaned spiral chute (such as figure 2 shown), the spacing of each line is 200mm,;
[0028] 3. Use No. 1 nylon brush (width 12mm) to apply a layer of paint on the drawn line. The paint is composed of 45% by mass: 20%: 25%: 10% NdFeB powder, emery, epoxy resin and polyamide curing agent;
[0029] 4. After the coating layer is dry, brush a layer of polyurethane wear-resistant layer on the surface of the entire spiral groove;
[0030] 5. Finally, a magnetizer is used to magnetize the linear direction of the linear coating coating. The magnetization intensity is 6000Gs. The improved spiral groove is used in...
Embodiment 2
[0033] The 5LL-1200 three-head spiral chute used in an ilmenite mine in Wuding, Yunnan is taken as the research object, and its pitch is 720mm.
[0034] The method for the recovery rate of magnetic minerals is as follows:
[0035] 1. Clean the three spiral grooves of the 5LL-1200 three-head spiral chute with water, and then dry it for use;
[0036] 2. The first spiral groove is not marked; the second spiral groove draws 12 involutes (such as image 3 shown), the distance between the outer ends of each line is 200mm; the third spiral groove draws 12 spoke lines (such as Figure 4 shown), the distance between the outer ends of each line is 200mm;
[0037] 3. Use No. 3 nylon brush (width 24mm) to apply a layer of paint on the lines drawn on the second spiral groove and the third spiral groove respectively. The weight percentage of the paint is 45%: 20%: 25%: 10% NdFeB powder, emery, epoxy resin and polyamide curing agent;
[0038] 4. After the coating layer is dry, brush a la...
Embodiment 3
[0042] The BL-600 double-head spiral chute used in the laboratory is taken as the research object, and its pitch is 360mm.
[0043] The method for improving the recovery rate of magnetic minerals in the spiral chute is as follows:
[0044] 1. First, rinse and dry the spiral chute used in production;
[0045] 2. Draw 4 circles of spiral shrinking lines on the surface of the cleaned spiral chute (such as figure 2 shown), the spacing of each line is 200mm,;
[0046] 3. Use No. 1 nylon brush (width 12mm) to apply a layer of paint on the drawn line. The paint is composed of NdFeB powder, emery, epoxy with a mass ratio of 60%: 15%: 20%: 5%. Resin and polyamide curing agent composition;
[0047] 4. After the coating layer is dry, brush a layer of polyurethane wear-resistant layer on the surface of the entire spiral groove;
[0048] 5. Finally, a magnetizer is used to magnetize the linear direction of the linear coating coating. The magnetization intensity is 500Gs. The improved ...
