Multifunctional Tubular Conveyor Chongqing Tubular Screw Grain Suction Machine Corrosion-Resistant Tubular Feeder. The spiral tube conveyor features a continuous spiral blade welded inside a cylindrical casing, with both the casing and the spiral blade rotating together. The added material, due to centrifugal force and friction, rotates with the casing and is lifted. Under the influence of gravity, the material then slides down along the spiral surface, causing it to rotate along with the spiral tube and thereby achieving forward movement. This mechanism is similar to a non-rotating screw moving translationally along a rotating nut, achieving the purpose of material conveyance. This machine has low energy consumption and maintenance costs; when feeding from the end, it can adapt to uneven feeding requirements and simultaneously accomplish various process needs such as conveying, stirring, and mixing. Even with excessive material input, it does not cause blockages; it facilitates multi-point loading and unloading and can convey high-temperature materials. It is suitable for horizontally conveying high-temperature materials and has good adaptability for processes involving high temperatures, uneven feeding, requirements for preventing breakage and contamination, and the need for multi-point loading and unloading. Practical experience has shown good results in conveying materials such as cement clinker, dry limestone, phosphate ore, ilmenite powder, coal, and slag. The particle size of material added from the end feed inlet must not exceed 1/4 of the screw diameter; for materials added from the middle feed inlet, the particle size must not exceed 30 mm. To prevent deformation of the cylinder, the feeding temperature must be controlled below 300°C. When conveying highly abrasive materials, this machine causes severe wear to the blades and trough. The screw conveyor designed this time is mainly used for conveying silica fume, which is highly abrasive, making it unsuitable for a spiral tube conveyor.
