1.Operating principle

WF series free classified for powder project is the whirlpool superfine classifier with the secondary air inlet and rotor horizontally mounted centrifugal classifier. Material and air (primary air) usually enter from the bottom cylinder (which is characterized by easy jet mill and air transportation facilities, do not need to set the raw materials and the air separation unit) being pre-dispersion, when the material rises to the classification of the periphery of the wheel, by the rotor centrifugal force, qualified product is discharged from the upper coarse particles fall back, with the red screen of the secondary air received again in the wind gate body, the fine powder and the meal are scattered again. The machine designed the gas seal isolation device at the face of graded round to ensure that the coarse particles can not mix with qualified products, and equipped with the structure of the gas seal at the bearing to guarantee the normal operation of bearings in high dust environments.

2.Performance characteristics

Wide grading range, High separation accuracy, high grading efficiency, simple structure, small footprint.With the combination of a mechanical grinder or a jet mill, it can increase the effective productivity. At the combination, the Heat-sensitive and Low melting point materials be allowed crushing into the machanicl grinder.

3.Scope of application

Due to the machine is a dry-type air classifier, it applies to the classification of non-stick material and can grade the globular, the lamellar and the fibrous materials, so as the profession of Chemical industry, Mineral, Building materials, Electronic, Pharmacy, Pesticide, Paint, Dye, Food, Metallurgy, Feed and so on, it can be dry classification of various organic and inorganic.
