In sand and gravel production, 0-4.75mm machine-made sand is formed after crusher, sand-making machine and vibrating screen. The machine-made sand contains certain powder. If used directly in concrete, the quality of concrete will be affected. In order to improve the quality of concrete, the powder content of manufactured sand must be reduced. Powder Separator also is known as powder concentrator is a kind of machine to separate the powder from sands.

When the powder separator is working, the selected sand and gravel enter the powder separator from the upper inlet port of the powder separator and fall on the combined propeller disc integrated with the rotor. Under the high-speed rotation of the disc, on the one hand, the material is scattered around by inertia centrifugal force, on the other hand, it is lifted upward by the upward airflow generated by the blade of the disc of the propeller, and the blade of the disc is shaped on the blade of the disc of the propeller. Material boils. The finer particles in the material float upward and are suspended and dispersed, while the thicker or heavier materials are scattered along the wall of the cylinder by the blades of the sprinkler tray, thus completing the first flour separation. The heavier materials and powder particles falling along the cylinder wall are dispersed, and the material curtain is formed when dripping device is used. Under the action of circulating wind, the fine powder is raised upward, classified again, and finally the coarse powder is discharged from the inner cone. A cage rotor is arranged above the discharging tray. The airflow near the surface of the cage rotor classification ring and the materials dispersed in the airflow are driven by the classification ring to rotate at high speed together with the classification ring to form a uniform and strong swirling airflow around the classification ring. The centrifugal force of material in airflow can be adjusted by speed regulating motor and spindle speed. When the rotational speed increases, the force also increases. At this time, if the treatment air volume is kept constant, the cutting particle size will decrease and the fine powder will become finer. If the rotational speed decreases, the fine powder will become thicker. Therefore, the fineness of the product can be flexibly adjusted and controlled according to the specific technological requirements, and at the same time, the fine modulus of sand and stone can be adjusted. Fine particles classified by cage rotor enter into each cyclone dust collector with circulating air. Because the newly designed cyclone dust collector adopts an efficient outlet structure, a guide plate is added at the snail horn of the intake, a reflection screen is added to the inner cone, and a decelerating plate is added at the lower end of the cyclone sleeve, thus greatly reducing the fluid resistance of the cyclone dust collector. The circulating wind enters the cyclone collector at a higher wind speed under the action of the guide plate. In the enlarged part of snail horn, the wind speed suddenly decreases, accelerating the particle deposition, and improving the dust collection efficiency of cyclone dust collector.
