Except grit product discharge valves, there are no any other moving parts outside of the entire device, so the running power consumption is very low. Based on the same reason, when operation, it runs without noise, so that it improved working site environment. Wear is small. Grit valve as the sole moving part abrasion resistance performance is good, and the cost itself is very low, occasionally replacement can be completed quickly. The bottom of grain ratings room is stream bed water supplying net, which is also the roof of rose tank. It uses high quality stainless steel material with special structure design. That not only guarantees forming uniformed stability stream bed, but also makes rose water form 2~3 mm of buffer water film under pulp layer. In such situation, the water film is able to support pulp without contacting with supplying water directly. So, it effectively protects stream bed water supply net surface from being wear. As long as rising water does not contain solid particle when the equipment in operation, at the same time detection system guarantees stability of maximum pressure, the service life of fluidized-bed water-supply net is almost unlimited.
In addition to obvious technical advantages, the biggest advantage of duplex flow classifier is unparalleled economic indicators. Combination of high grade efficiency, large capacity, low footprint and advanced technology of multiple hierarchical, reduces construction investment and running costs to a large extent. Since above statement of low wear, low power consumption, it leads to compound fluidized classifiers lower investment. And the running cost is significantly far lower than other devices, which is also one of the biggest advantages.
Zhengzhou Hongxing mining company has produced a set of Allflux dual fluidized classifiers began to put into use in the world famous Zhengzhou Hongxing Company at main mineral processing plant in July 2002. It replaced the original 2 series of grading equipment, and selected fine magnetite ore, which was a great success. The device model is AFX-1 500. Ore handling capacity is 280 Uh, ore density is 4 500 kg/m ', and slurry density is l370 kg/m3. The pulp concentration is 35%. The largest feeding ore particle size is 850 um, P ∞ is 140 F.cm,-44 UM takes account 20%--35%. From small lab to large industrial equipment, there are a variety of specifications and models of composite flow layer classifier. Stand-alone solid handling capacity is generally between 10-1 000Uh, solids content (concentration) is between 10%--75%. Slurry handling capacity is between 20-2 500 m'/h, and upper limit of feeding particle size is generally 8mm.
