◇The special airfoil guiding device was used to reduce the air friction and the power consumption so that the grain gradation and classification accuracy of products is better and the quality of product greatly is improved.

◇Turbine classifying blade is adopted.which makes classifying space of separation area expand 5-10 times than other type separators.

◇A baffle device is installed inside the grading rotor of the powder selection machine to eliminate eddy currents, greatly reducing the air resistance of the rotor and saving energy consumption.

◇The grading blades, dispersing device, airfoil guide device, and vortex adjustment device on the rotor are all made of special wear-resistant materials, which greatly extends the service life of various components of the powder selector and improves the operation rate of the entire grinding system.

◇ The main bearing of the rotor adopts dry oil lubrication method, which greatly improves the operation rate and reliability of the equipment, and reduces the maintenance intensity.

◇ A secondary material blocking ring has been added to the upper part of the powder selection machine rotor to prevent unnecessary wear caused by direct material erosion of the grading blades and improve the service life of the grading blades.
