I. Metal Mine：Hydraulic cyclone manufactured by Tongge Company widely applied in mine-chosen technique in various metal mines. It mainly shows in the following works:1. Classification for section I closed circuit grinding 2. Classification for section II closed circuit grinding 3. Regrinding for fine mine classification 4. Mud-removing before selection and after selection 5. Dam and backfill for gangue.
　　In closed circuit grinding system, it features high classification efficiency and fine overfall fineness under high mine concentration. Classification efficiency is higher for 5-10% than common screw grader. It benefits for enhancing grader utilizing coefficient. Choose proper specification and mode of cyclone according to grinding processing capacity, overfall fineness and sedimentation concentration. This is precondition of getting the most optimized work condition. Tongge Company is able to offer stand-alone, parallel connection machine or machine series in such specs as Φ50, Φ75, Φ100, Φ125, Φ150, Φ200, Φ250, Φ300, Φ350, Φ500 and Φ660. Fine sand, less than 37μm, in gangue can not be used as dam materials during selecting mine. After the classification by cyclone, coarse granule left in the bottom of dam, fine granule move to the tail of gangue. Fine granule graded naturally during the movement. There is section full of clean water, which can be used for calling back of water. In the process of filling tail, we utilize cyclone for grading and concentrating to separate coarse granule so that to reduce load of filtering machine and to reach at the best effect. Use cyclone to finish dam and filling work so that to solve problems such as leaking mine, sink and overproof water discharged. So it can receive obvious economic and social benefit.
II. Wet Method of Desulfuration for Smoke and Gas for Heat-Engine Plant
Limestone Classification Cyclone We always use closed circuit grinding system composed by cyclone and ball mill in preparation system of limestone. Generally, we usually use medium and small specification, cyclone with small cone angle, overfall fineness of cyclone can reach at -325 ≥90% Cyclone for Grading Gesso Fit for concentrating gesso and reduce pressure in following procedure for vacuum belt spin-drier; choose small cone angle, small diameter of cyclone. Separated granularity is 10~44μm; quality concentration at the bottom of cyclone is 40~55%; adopt PU, NM wearable materials in cyclone, which features good wearable capacity and long life time. Cyclone for Grading Sulfur and Ammonia Choose cyclone with corresponded specification according to technique, separation granularity 50~100μm; concentration multiplying power of bottom flow is 3~4 times; adopt PU, NM wearable material in cyclone, good wearable performance, long lifetime.
III. Sand and Mud Separator for Oil Field
Utilize cyclone for separating sand and mud during petroleum drilling work to purify slurry. UseΦ250（10′′）, Φ300（12′′）cyclone for removing more than +45μm of rock debris, use Φ100（4′′）, Φ125（5′′）cyclone to eliminate more than +15μm of rock debris, useΦ50（2′′） cyclone for getting rid of +10μm rock debris. Hydraulic cyclone manufactured by PU elastomer features in wearable, anti-aging, light and so on. Fit for outdoor work. Feature in efficient grading and small classification granularity for its special structure.
IV. Wash and Select of Coal
Cyclone without Pressure for Feeding but With Heavy Medium Structure Characteristics: There are three exits for discharging. Separate eligible fine coal, medium coal and recrement from single concentration of suspension. High precision, wide range of granularity selection, adapt broad range. Picked material and suspension enter into cyclone separately, save electricity consumption, reduce recrement and secondary coal capacity. Fit for reasonable arrangement of technique process. Simple structure, without moving components; adopt high aluminum porcelain for separating manufacturing; features in good wearable performance and long lifetime. Fit for selecting high sulfur, original coal which is hard to pick.
