According to the construction section, it is divided into one-stage grading cyclone and two-stage grading cyclone.
According to the function, it is divided into classification cyclone, dehydration cyclone, desliming cyclone, slag removal cyclone, thickening cyclone, tailings dry discharge special cyclone.
Folding a section of grading cyclone
The first-stage classifying cyclone is widely used in various metal ore and non-metallic mineral processing plants with a single-series daily processing capacity of more than 500 tons, and forms a closed-circuit grinding and classifying cycle with the first-stage ball mill. According to the different processing capacity, the hydrocyclones can be arranged in a single unit or in groups. In the case of higher ore concentration, it has higher classification efficiency and finer overflow fineness, and the overflow product is uniform, and the extension efficiency is 5-10% higher than that of the commonly used spiral classifier, which is beneficial to the mill. Improvement of utilization factor.
(1) Dazhui angle cyclone
The cone angle of the cyclone is relatively large, up to 180 degrees (also known as the flat cyclone), which is suitable for the treatment of high concentration, large mineral specificity, and overflow fineness requirements of -200 mesh below 60%, especially suitable for stage grinding The first stage of iron ore grinding in the beneficiation process. The cyclone with this structure has a series of advantages such as uniform overflow particle size, less overgrinding of overflow products, and large adjustment of underflow yield without affecting the normal operation of the cyclone. Compared with the same cyclone, It can increase the processing capacity of the first stage of grinding by 10-25%.
(2) A section of high-fineness grading cyclone
It is suitable for occasions where the grinding fineness of -200 mesh is more than 80% in the first stage of grinding. Due to the fine grading particle size, even if the ordinary structure cyclone reaches the required grading particle size, the grading efficiency will be greatly reduced, the amount of sand returning will increase, and the new ore feeding amount of the mill will be low. A section of high-fineness classifying cyclone reduces the degree of overflow coarseness and underflow fineness through structural changes, and maintains high classification efficiency while obtaining higher overflow fineness.
Folding two-stage grading cyclone
The two-stage classifying cyclone is widely used in the second-stage inspection and control classification of various metal ore and non-metal mines. The specifications of the cyclone range from 75mm to 660mm, which can be applied to the processing plants with different processing capacity and different requirements for the grinding fineness. The cyclone adopts a unique structural design, which allows the overflow fineness of the second-stage cyclone to be arbitrarily selected and adjusted from -200 mesh 75% to 95%.
JY series cyclone is a new generation of high-efficiency grading cyclone developed and produced by our company on the basis of absorbing and digesting the classification technology of Krebs cyclone in the United States. This series of cyclones has the advantages of high classification efficiency and classification accuracy, large single processing capacity (single processing capacity 4-550m3/h), and long service life. It has been successfully applied in mine classification operations.
Folding dehydration cyclone
The dehydration cyclone is mainly used for the dehydration of various mineral slurries. According to different material characteristics and different production and installation environments, different structural designs are adopted, which have the advantages of low pressure drop, large processing capacity and high dehydration efficiency. Applied in a tailings re-selection, pulping and dehydration operation, when the feed concentration is 5-12%, and the -200 mesh content is 75%, the average concentration of the overflow of the cyclone is controlled below 1.5%, and the effective In case of dehydration purpose, the loss of useful minerals is avoided. In the dehydration application of a certain silica sand, the overflow concentration of the dehydration cyclone has reached below 0.5%, and the overflow is almost unqualified fine mud, which achieves the double effect of dehydration and desliming. The overflow water of the cyclone After settlement, it can be reused to save cost.
Folding desliming cyclone
The high-efficiency desliming cyclone is mainly used for desliming operations of various metal ore and non-metallic slurries. On the basis of absorbing excellent foreign achievements, the high-efficiency desliming cyclone has determined the proportion and coordination of the main components of the high-efficiency desliming cyclone after several years of practice. The high-efficiency desliming cyclone designed and produced has desliming efficiency High, less loss of useful minerals, saving user costs, and improving production efficiency. Case: The argillaceous minerals of tailings discarded by a silica sand mine accounted for 12.7%, the fineness -325 mesh accounted for 39.3%, and the argillaceous minerals were almost all stored in the -325 mesh level.
Folding slag cyclone
Slag removal cyclone: used in power plant wet desulfurization, lime pulping, crude oil slagging, tap water sand removal, sewage treatment, etc., can effectively remove coarse sand, metal and other particles in the slurry, and has the ability to remove slag It has the advantages of high efficiency and less loss of useful slurry.
Folding concentrated cyclone
High-efficiency concentration cyclones are often used in conjunction with thickeners, filters, etc., and are used in the concentration of various minerals before filtration, mineral fine grinding flotation, gold slurry cyanidation, etc., and high concentration of tailings In transportation and other operations, the Concentration of ore pulp is realized.
The high-efficiency concentration cyclone is rarely used alone, and is often used in combination with other equipment. The structure and installation of the concentration cyclone can be adjusted according to customer requirements and the specific conditions of upstream and downstream operations to optimize the use effect. The flow device uses a unique internal structure design, which can generate a higher underflow concentration under the premise of a lower overflow concentration, improve production efficiency, reduce expenditure, and save costs.
