Product Description Product Descriptionrotary feeder Principle of operation and main featuresRotary feeder is also known as rotary valve, star feeder, and air lock. The usual rotary feeder structure (as shown in the figure) is a rotor with several blades rotating in the circular and simple shell. The materials falling from the upper hopper are stuffed in the space between the blades and discharged with the rotation of the blades to the lower part.The high-pressure gas brought by the impeller rotation can be sucked away from the mouth, reducing the phenomenon of gas topping, which is conducive to the smooth fall of the material.For the pneumatic conveying system of pressure and suction, the rotary feeder is one of the main components, which can supply material uniformly and continuously to the conveying tube, and in the separation and dust collection part of the system, it has the function of air lock and discharge.Main featuresAs feeders, rotary feeders are used in a wide range of applications. It is used for discharging materials and dust in the lower part of the separator and dust collector in the suction-fed pneumatic conveying system; it is used for feeding materials at the beginning of the conveying end in the pressure-fed pneumatic conveying system. The reliability of our company's rotary valve comes from nearly thirty years of experience and professional development, with the most reasonable structure and high quality material manufacturing, can effectively transport powder and granular materials with the following characteristics:1.Simple structure, easy to use and maintain2.Compact structure, small external dimensions, small installation space3.Easily changeable feeding volume by adjusting the speed4.The discharge volume changes very little as the material changes and the amount of material stored in the upper separator, etc.5.Airtightness with a certain number of layers6.Virtually no breakage of conveyed materials7.The material can be transported when the temperature is less than 500oC8.Highly padded, patented anti-seize, abrasion-resistant, specific models for safe pneumatic movement under load Usually, it is applied to powder and small lumps with good flowability and less abrasiveness.Selection
