Working principle of screw feeder

With competitive price and timely delivery, dahe sincerely hope to be your supplier and partner.

The working principle of the screw feeder The screw feeder is widely used in vertical packaging machines in various industries'>vertical packaging machines, which can be used to convey powder, granular and small pieces of materials horizontally or obliquely. It has simple structure, small cross-sectional size, good sealing performance and reliable operation, which is convenient for intermediate loading and unloading, and can also stir, mix, heat and cool materials during the loading process. The working principle of the screw feeder can be divided into the following three types: gravity sliding method. The rotation speed of the screw is low, and the material on the screw surface is affected by gravity far more than the centrifugal force. Because the rotating material of the screw continuously slides down the screw surface, resulting in axial displacement, the cx screw machine basically belongs to this principle. The filling factor value of the screw machine of this principle is generally less than 0.5. Because of too much filling, the material does not slide down the helical surface, and the spiral agitation makes the material fall over the helical shaft, and a large axial speed cannot be obtained. It cannot be used for vertical helical or upward conveying with a large inclination angle. push method. The pushing method is used for unloading and conveying at the bottom of the silo. The material is often filled with the screw, and the static pressure of the granular material is relatively large. The gravity of each grain of material itself is much smaller than other forces (screw thrust, friction, static pressure). The resistance of this kind of spiral is very large, and it has to overcome the friction force formed under the larger pressure. Centrifugal induction. It is used for vertical screw conveyors with steep inclination, or any screw conveyors with high rotation speed. The effect is far greater than the influence of other external forces such as gravity.
