Soil shaftless rice round tube screw conveyor round tube screw ash conveyor,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 rotates with the casing due to centrifugal force and friction, is lifted, and then slides down along the spiral surface under gravity, causing the material to rotate with the spiral tube and move forward. This mechanism is similar to a non-rotating screw moving translationally along a rotating nut, achieving the purpose of conveying materials. This machine has low energy consumption and maintenance costs; when feeding from the end, it can adapt to uneven feeding requirements and simultaneously complete various process requirements such as conveying, mixing, and stirring. It does not jam even when excessive material is fed; 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 anti-breakage and anti-pollution, 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 rock, ilmenite powder, coal, and slag. The particle size of materials added from the end feed inlet must not exceed1/4of the spiral diameter; for materials added from the middle feed inlet, the particle size must not exceed30millimeters. To prevent deformation of the cylinder, the feeding temperature must be controlled below300°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 silicon micro powder, which is highly abrasive, making it unsuitable for a spiral tube conveyor.When material is added to a fixed trough, due to the gravity of the material and the friction between the material and the trough, the material accumulated at the bottom of the trough does not rotate with the spiral body but is pushed forward by the rotating spiral blades. This is similar to a non-rotating nut moving translationally along a rotating screw, achieving the purpose of conveying materials. This machine facilitates multi-point loading and unloading and can simultaneously complete mixing, stirring, or cooling functions during conveyance. It is sensitive to overload and prone to clogging; it causes breakage and loss of materials. The horizontal screw conveyor has a simple structure, making it easy to install, maintain, and troubleshoot. It is suitable for horizontal or slightly inclined (20oor less) continuous and uniform conveyance of loose materials. The working environment temperature is-20—+40°C, and the material temperature during conveyance is-20—+80°C. Its rotational speed is relatively lower compared to vertical conveyors, and it is mainly used for horizontal or small inclination angle conveyance of materials, with a conveyance distance generally not exceeding70meters.Soil shaftless rice round tube screw conveyor round tube screw ash conveyor.
