Lime Powder Screw Conveyor is an enclosed conveying system designed to continuously transport lime powder, hydrated lime, quicklime powder, calcium carbonate powder, and other dry fine powders. It is suitable for conveying powder between storage silos, mixers, processing equipment, and packing systems. Depending on the material and layout, the conveyor can be configured for capacities of 2–25 t/h and conveying distances of approximately 1–30 m.
The screw conveyor uses a rotating screw inside an enclosed housing to move lime powder from the inlet to the discharge point. Horizontal and inclined configurations are available according to the plant layout, while the screw diameter, motor power, conveyor length, and construction material can be selected according to the required capacity and conveying conditions. The enclosed structure also helps reduce powder leakage and dust dispersion during continuous conveying.
A Lime Powder Screw Conveyor works by rotating a screw shaft fitted with helical flights inside a conveyor housing. When lime powder enters through the inlet, the rotating flights push the material forward along the conveyor until it reaches the discharge outlet. The conveying speed and capacity depend on factors such as screw diameter, rotational speed, material characteristics, filling rate, and conveying angle.
For lime powder applications, the enclosed conveyor housing helps contain fine powder during transportation and reduces the amount of material exposed to the surrounding working environment. The conveyor can be arranged horizontally or at a suitable inclined angle to connect equipment such as storage silos, mixers, feeders, and packing machines.
The configuration of a Lime Powder Screw Conveyor depends on the required conveying capacity, distance, installation layout, and characteristics of the lime powder. Different conveyor structures can be selected for horizontal conveying, inclined conveying, limited installation space, and applications that require a more enclosed conveying path.
U-type screw conveyor: The U-shaped housing provides convenient access for inspection and maintenance. It is suitable for many horizontal powder conveying applications where regular cleaning or maintenance is required.
Tubular screw conveyor: A tubular housing provides a more enclosed conveying path and is suitable for dry fine powders such as lime powder. It can help reduce powder dispersion during transportation and is useful when dust control is an important consideration.
Inclined screw conveyor: An inclined configuration can be used when lime powder needs to be conveyed to a higher discharge point or when the production line requires an elevation change. The conveying capacity and motor power should be selected according to the conveying angle and material characteristics.
Vertical screw conveyor: Vertical conveying can be considered where available floor space is limited and the process requires material to move upward. The actual configuration should be determined according to the required lifting height, capacity, material properties, and equipment arrangement.
Shaftless screw conveyor: Shaftless designs are generally more suitable for sticky, wet, or easily bridging materials. For dry lime powder, a conventional shafted screw conveyor is often more appropriate, depending on the material condition and conveying requirements.
For most lime powder conveying applications, the appropriate configuration should be selected based on the actual conveying route rather than the material name alone. Capacity, conveying distance, installation angle, inlet and outlet position, and required dust control should all be considered before determining the conveyor structure.
Lime powder is a fine and dusty material, so a controlled and enclosed conveying method is important. A screw conveyor provides a continuous conveying path and can be configured according to the required capacity, conveying distance, and installation layout.
Enclosed conveying: The enclosed screw and housing help reduce powder leakage and material exposure during transportation, making the conveyor suitable for conveying lime powder between silos, processing equipment, and packing systems.
Continuous feeding: The rotating screw continuously moves lime powder from the inlet to the discharge point, making it suitable for steady feeding to mixers, feeders, packing machines, and other downstream equipment.
Flexible installation: The conveyor can be arranged horizontally or at a suitable inclined angle. Conveyor length, inlet and discharge positions, and other dimensions can be configured to fit different production line layouts, including installations beneath storage silos or between processing units.
Customizable capacity: Screw diameter, rotational speed, motor power, and conveyor length can be selected according to the required throughput, conveying distance, material characteristics, and installation conditions.
Easy integration with production lines: The screw conveyor can be connected with storage silos, mixers, feeders, packing machines, and dust collection systems to provide continuous lime powder transfer between different processing stages.
Lime Powder Screw Conveyor is mainly used for dry powder materials that can be continuously conveyed by a screw mechanism. Besides lime powder, the conveyor can be configured for hydrated lime, quicklime powder, calcium carbonate powder, fly ash, cement powder, and other similar dry powders. The actual conveyor configuration should be selected according to material characteristics, required capacity, conveying distance, and installation conditions.
