Powder Concentrator

Three-grain separation high-efficiency classifier is the newest high-tech products developed based on international advanced powder classifying principles and by adopting aviation aerodynamic analysis method. This product breakthroughs the two-grain (coarse powder and fine powder) separation theory and divides the materials into three types (coarse powder, medium powder and fine powder), with simple configuration.

In the working status, high-speed motor drive vertical shaft to rotate through the transmission device and the materials enter into the powder concentrating chamber through the feed inlet at upper part of the power concentrator. After that, the materials will fall on the material scattering plate through the power passing pipeline set between the upper and lower cones of medium-and-coarse power collection cones, and the material scattering plate rotates with the transmission shaft. Under the inertial centrifugal force, the materials will be scattered around evenly, and in the external fans, the materials are influenced by the high-speed air flow entering into the powder concentrating chamber through air inlet. Under the inertial centrifugal force, the coarse particles in the materials are thrown to the inner wall of the power concentrating chamber and then fall along the wall on the coarse power collection cone, and other particles will be impacted up by the air flow that spun upward. When passing the action area of large fan blades, some of the coarse particles will be thrown to the inner wall of the power concentrating chamber and then fall along the wall on the coarse power collection cone.

After passing the large fan blades, under the action of upward air flow, the medium and fine powder will enter into the secondary power concentrating area through the vertical guide blades. Under the action of the strong and stable plane eddy formed in the rotating cage-shape rotor, the dust-containing air flow throw the medium and fine powder to the vertical blade and loss their energy of motion, and then fall in the coarse powder collection cone, and finally be discharged through the medium and coarse pipe. The fine meeting requirements can pass the cage-shape rotor and enter into the high-efficiency low-resistance cyclone separator and then fall in the fine powder collection cone and become finished products.
Features:
1. Innovative design: With new-style assembled design method, it is integrated with advantages of original centrifugal type, cyclone type and double rotor type, which greatly lower the energy consumption.
