Application of Hydrocyclone
principle
cyclones are widely used in our non-ferrous and ferrous metals ore grinding process of grading work has widely replaced spiral classifier, but also can be used with gold, concentration,
la gears, TAILINGS DAM, kaolin sorting, filtering, pulp slag and other operations. Cyclone devices have small size, small footprint, low power consumption all year round, graded, high efficiency, large capacity, no moving parts, maintenance, and small amount of advantages.
cyclone feed pulp flow in the centrifugal force generated to carry out solid-liquid separation, the quality of large particles to the wall of cyclone movement along the conical section of the cylinder wall accelerating downward spiral, from the cyclone device at the bottom of settling the discharge port, the quality of small particles in the role of the axial velocity field force, to the cyclone center movement, excreted through the overflow pipe.
industrial applications
1, metal mine Hydrocyclone
closed-circuit closed-circuit grinding mill ore grade
hydrocyclone is provided in order to obtain uniform particle size of the grinding minerals class machine Closed-circuit grinding role in the hydrocyclone,
la gears sneakers, while the size of the product provides access to overflow, while the other is to keep the mill in the total load, the load of the size composition and solid content and other aspects to best practices. According to the different processing power, with the required fineness, the company provides the user Φ50, Φ75, Φ100, Φ125, Φ150, Φ200, Φ250, Φ300, Φ350, Φ500,
la gear womens shoes, Φ660 other single, parallel or serial unit unit. I produced a cyclone has been widely used in grinding, two stage grinding, grinding and then concentrate grading operations to get good results.
closed mine
Concentrate cyclone cyclone mill tailings with the filling and concentrator tailings dam
sent to tailings, the tailings should not be less than 37μm in the sand as the tail Mine dam material. Classification using the cyclone, the coarse tailings dam area to stay in, fine tailings pond to the end of exercise, the process of fine pulp and naturally in the flow classification, thin, thin flow of process tailings naturally graded, in the end of the tailings is to clarify the water for some areas, can be used as a backwater. The end of filling the whole process, using the cyclone pre grade enrichment, the majority of pre-separation of coarse particles down to reduce the load on the follow-up filter, can achieve better results. Complete with cyclone dam and filling operations can solve mine tailings dam leakage, beach collapse, excessive drain off water and other issues, can be achieved remarkable economic and social benefits. Last pulp slurry enrichment and enrichment and to clarify the clarification
centrifuge swirler role of solid particles in the pulp was spun off from the liquid phase, thus completing the concentrated slurry or clarification operations. Abroad instead of using the cyclone thickener successful precedent. I worked in iron ore, gold, molybdenum and other metal ore mining in the pre-concentration using hydrocyclone overflow into the thickener, and the cyclone thickener underflow stream bottom can reach almost the same concentration. This will greatly reduce the thickener and the filter loads. But the concentrated and clarified the purpose of hydrocyclone different in operation, are different in structure. Requires concentrated cyclone underflow high enough concentration.
2,
la gear sneakers, non-metallic mining Desanding Hydrocyclone wet cyclone
non-metallic minerals beneficiation process, the ore slurry dispersed by the pound, the slurry contains a certain amount of quartz sand or impurities Therefore, a fine grade grit removal and the premise of removing impurities. Conducted using hydrocyclone Desanding operations will show a larger convenience. According ore impurities, particle size distribution, processing power, etc. determine the type and specifications of cyclone. Now more commonly used Grit Cyclone specifications Φ350, Φ300 (200 mesh particle size separation), Φ150,
la lights, Φ75 (325 mesh particle size separation), Φ50 (separation size of 600 mesh). However, due to the different nature of ore, and sometimes tend to use several devices or several different sizes of cyclones in series so as to achieve technical requirements.
Fine grade flow classification for fine particles, generally used Φ10-Φ50mm polyurethane cyclone. Cyclone for fine classification with a larger cylinder part and the part of the small cone angle, the use of polyurethane material, making it good wear resistance and no colored pollution. As a smaller diameter cyclone, cyclone capacity single small, generally in parallel into the group.
3, Hydrocyclone chemical in the chemical industry in the liquid-solid separation unit operation can be used for enrichment or clarification of cyclone operation. Cyclone can be separated from the solid particles larger than 10μm. If the solid particles in the solution does not appear within 5-10 minutes, using the material in a short residence time of cyclone characteristics can be separated. Technology is widely used at present are:
Centrifuges, filter before the pre-concentration, optimization of centrifuges, filter working conditions; Recovering useful for solid particles; emulsion Grit; industrial circulating water, grit removal, cleaning; crystal controlled crystallization process of refining the particle size sewage treatment.
