WORKING PRINCIPLE QLFW classifier and feeder, cyclone separator, dust collector, induced draft fan, control system constitute a set of grading system. Material in the negative pressure under the action of the wind through the feeder quantitative rose to classification, rotating at high speed the classification of turbine under the action of the strong centrifugal force, the thickness of material separation, conform to the requirements of the particle size of the fine particles, through the classification of blade clearance into cyclone separator or dust collection, coarse particle entrainment of fine particles bump wall disappeared rate after, along the wall fell to a secondary tuyere, After the strong washing action of the secondary air, the fine particles are separated from the heart body, and the fine particles rise to the secondary classification of the grading area. The separated coarse particles are discharged through the known powder device.…
