Efficient classifier performance advantages are obvious, but the separator body without fine collection device to be equipped with its air volume to match the dust collection bag or large-sized electrostatic precipitator to collect the finished product, which undoubtedly greatly increasing the system investment, but also the complicated process layout, operation control difficult, to some extent, limit the application of high-efficiency classifiers. Structural features and efficient dual-rotor type separator as follows: 1, using centrifugal force field field as grading, dual cage rotor structure. Taking into account the characteristics of air movement within the separator and the distribution of the rotor using inverted cone structure to ensure the stability of separator classifying chamber graded force field. 2, cage rotor and sprinkle trays installed together on the spindle with the speed motor drive, thus ensuring the strength of the force field can be flexibly adjusted graded by changing the motor speed, the forces to change the classification of particles in the force field, hierarchical control cut size, adjust the product fineness and particle size composition. 3, high dispersal ability propeller spreaders reel, so that the material can be more evenly dispersed in the classification area, the use of restraint cone to stabilize the gas flow field separator chamber and the annular inlet trickle together form a secondary sorting device structure to enhance the secondary sorting effect, reducing the amount of coarse powder mixed in. 4, fine collection of small size and efficient use of multiple parallel cyclone, arranged in the separator around the body to form a whole, on the one hand to improve the separation efficiency of fine powder, on the other hand, compared with other high efficiency separator, simplifying the system processes, saving system investment, regulation, control more convenient. 5. The air volume separator using external circulation fan supplied by classifier the lower cut wizard named powder, and by trickle diversion effect tube to form a rotating flow field into the separator chamber rises, and by spreading reel dispersed in the area of ??material mixing, forming a more stable flow field grade classification of materials, fine grading after carrying out of the flow separator, import cyclone achieve solid separation. Thus, the air volume within the separator can be obtained by adjusting the fan duct valve control, with variable speed rotor cage together, adjust the classification of indoor classification Field, and then control the product fineness and particle size composition. Determined by the structural characteristics of the above, and by experimental research and production applications show that efficient dual-rotor type separator has the following characteristics: 1, the material in the classifying chamber, the role of a strong cyclone and radial shear in , the material good dispersion and high strength, high classification efficiency. 2, the sorting of materials have been classifying zone grading interface clear and stable conditions for each part of the separator, so choose high-grade powder machine precision. 3, easy to adjust the fineness and reliable, and a wide adjustment range can be flexibly controlled by adjusting the spindle speed and air flow. 4, can yield 40-60% open circuit grinding, the powder efficiency up to 85%. Under such circumstances the existing cyclone separator or a centrifugal separator to transform, can not change the main structure and the motor load, ensuring efficiency above 85%, an increase of 20-30%.
