Flexible screw conveyor for conveying lines need to press the space curve any arrangement to avoid material reproduced occasions; when the inner casing into the plethora of materials or lumps of material wholesale spiral conveyors, spiral appreciate the freedom to float, not will produce jam phenomenon; noise. Mainly used simultaneously horizontal and vertical transport of materials. General requirements for the vertical conveyor speed is higher not lower than 1000r / min. Spiral conveyor is welded in a cylindrical housing with a continuous screw blade, the casing rotates together with the helical vane. Added materials due to the centrifugal force and friction force random shell rotates together and lifted after spiral conveyors Which is good, the material under gravity has slipped along spiral conveyor screw surface, so that the material along with the Spiral rotation in order to achieve the forward movement of the material, does not rotate as the rotation of the nut screw along a translational movement, as the purpose of conveying the material. Which is good spiral conveyors, Ruifeng (certified), Beibei District spiral conveyor is provided by Ning County Ruifeng machine parts processing department. Ning County Ruifeng machine parts processing at (sdysjx.cn.s07.ctrl.net.cn) is Dezhou, agricultural machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs. In Ruifeng leadership with the staff warmly welcome all inquiries negotiations to create a better future Ruifeng.
