Our company is specialized in powder conveying, grading equipment research and development and production of high-tech enterprises, the research and development of JDF series ultrafine powder classifier won a national invention patent and utility model patent, was awarded the title of high-tech products in jiangsu province at the same time, more than forty power plants across the country and more than eight hundred cement plant has been widely used. And walk in the forefront of the industry in large-scale, able to produce and processing capacity of 100 t/H fly ash of 600 t/H superfine cement oversize efficient classifier JDF series ultrafine powder classifier is introduced in 2000 have the classification field the most advanced Japanese onoda O - Sepa classifier based on the technology of the digestion and absorption, the successful development of independent innovation of a new type of efficient classification equipment.

I. special advantages of fly ash classifier:

1, the design of the cage rotor is a straight from multi-layer horizontal partition and vertical profile classification of cage rotor, horizontal clapboard make the level of the staging area air to form stable vortex, special-shaped grading blade makes the classification of air flow from inside the cage surface into the cage at any point is keep the same velocity, the relative velocity difference < 5%, so the staging area of flow field uniformity and stability, and therefore a high classification accuracy.

2, in the middle of the cage rotor and outer shell between parts evenly arranged several blocks with "concave" glyph slot guide vane, dusty gas must be from the guide vane is about 15 mm between several cracks along the tangential into ring composed of guide vane and cage rotor classification space, as a result of the existence of guide vane eliminate side wall effect, crude ash of fine ash content is greatly reduced, classification efficiency increased significantly.

3. The coarse ash falling into the coarse ash bucket is washed by the lower updraft, and the fine ash in the coarse ash is again brought into the grading area for grading.

4, due to the flow field uniform stability, higher airflow rotating speed, centrifugal force generated by the suction of the gas flow to the heart is very strong, and classification accuracy is high, and the feed gas ratio can reach 2.0 ~ 2.5, the turbine classifier material gas is higher than (0.7 ~ 1.0) 2 ~ 3 times, classified with air volume is only half of the turbine classifier, thus the system energy consumption greatly reduced, the processing capacity of 60 t/H classification system is only 120 kw of energy consumption, processing capacity of 40 t/H classification system energy consumption is only 100 kw.
