Description

Technical Field

[0001] The invention relates to a screening device for determining the quality of mining samples in a mine. Background Art

[0002] Ore dressing is the most important link in the entire mineral production process and is a key department in mining companies. Generally, large-scale mining companies are resource-based enterprises that integrate mining, selection and smelting. The process of separating useful minerals from useless minerals (usually called gangue) or harmful minerals in mineral raw materials by physical or chemical methods, or separating multiple useful minerals is called ore dressing, also known as "mineral processing". Among the products, the ones with enriched useful components are called concentrates; the ones with enriched useless components are called tailings; the ones with useful components between concentrates and tailings and need further processing are called middlings. Metallic mineral concentrates are mainly used as raw materials for extracting metals in the smelting industry; non-metallic mineral concentrates are used as raw materials for other industries; and the selected products of coal are clean coal. Ore dressing can significantly improve the quality of mineral raw materials, reduce transportation costs, alleviate the difficulties of further processing, reduce processing costs, and realize the comprehensive utilization of mineral raw materials. As the world's mineral resources are becoming increasingly scarce, more and more poor and complex ores are being used, so the amount of ores that need to be processed by ore dressing is increasing. Except for a few rich ores, almost all metal and non-metallic ores require ore dressing. There are not many rich ores in nature that can be used directly for smelting. Especially with the development of industrial production, the reserves of rich ores are gradually decreasing, so more and more poor ores have to be mined. However, it is not economical to use low-grade poor ores for smelting. In order to reduce smelting costs, effectively extract useful components from ores, and comprehensively utilize national resources, the ores mined from mines must be beneficiated before smelting. The process includes: (1) preparation operations, namely crushing, screening, grinding and grading; (2) separation operations, namely selectively recovering useful minerals and discarding gangue minerals to the maximum extent, so that different useful components in the ore are enriched in different products. The methods include: gravity separation, flotation, magnetic separation, electrostatic separation, and photoelectric separation. Summary of the invention

[0026] The outer edge of the top of the driving disc 12 is a large toothed disc, and the large toothed disc and the small toothed disc are linked by a chain transmission;

[0027] The sample storage tube 9 is a hollow tube, and a leakage groove 91 is transversely opened on the outer wall of the sample storage tube 9. The leakage groove 91 is covered with a leakage baffle 10. The sample storage tube 9 is inserted into the drum 8, and the outer periphery of the drum 8 is sealed with a grid hole 81.

[0028] One end of the roller 8 is fastened to the sleeve member 11 by bolts, and the other end of the roller 8 is fastened to the bearing sleeve 6 by bolts; the bearing sleeve 6 is a through cylinder, and a bearing is arranged outside the bearing sleeve 6, and the outer ring of the bearing is placed and fixed on the side bracket seat 5; the air filter element 61 is covered in the bearing sleeve 6;

[0029] A bellows bracket 3 is welded and fixed on the side wall of the support platform 1, and a bellows 4 is fixed under the bellows bracket 3. The bellows 4 wraps around the annular area of ​​the outer periphery of the roller 8 by one third to two thirds, and there is a distance of 2.2-13 mm between the roller 8 and the bellows 4; an air core rod 7 is passed through one side of the bellows 4;

[0030] The probe tube 13 is plugged with a feed tube 15 and an air filling tube 16; the probe tube 13 and the feed tube 15 and the air filling tube 16 are first clamped with rubber pads, and the gap is sealed with a fiber ball; the extended ends of the feed tube 15 and the air filling tube 16 are both passed into the sample storage tube 9.

[0036] The composition principle of the present invention is as follows: the sample storage tube 9 is a tubular cylinder for collecting mineral samples, and the feed tube 15 will continuously transport the mineral samples into the sample storage tube 9, and this transportation is driven by the high-pressure gas charged into the inflation tube 16; the mineral samples enter the sample storage tube 9, because the driving disk 12 can drive the roller 8 to rotate, and the probe tube 13 and the feed tube 15 and the inflation tube 16 are clamped with rubber pads, so the sample storage tube 9 remains stationary, and the roller 8 rotates with the rotation of the driving disk 12.

[0037] Since the mineral samples injected into the sample storage tube 9 are sent in by high-pressure air, the mineral samples are in a disordered tumbling state in the sample storage tube 9. The particles with diameters that meet the specifications of the leakage baffle 10 will leak out to the inner wall of the drum 8. The rolling of the drum 8 will grind the leaked mineral samples into particles of the same specifications, which will eventually be discharged from the grille holes 81.

[0038] The bellows 4 designed on the drum 8 is used to blow away the dust during the grinding process of the mineral sample. The air filter 61 designed on the bearing sleeve 6 is used to discharge the high-pressure gas injected into the sample storage tube 9.
