Powder Screw Feeder Conveyor for Chemical Industry is used to transfer chemical powders from one location to another, and from low to high elevations. It flexibly facilitates the transfer of chemical powders between different workstations and at different heights. It can perform both horizontal conveying and inclined/vertical feeding from low to high. A single unit can achieve a horizontal conveying length of up to 30 meters and a vertical conveying height of up to 5 meters, fully adapting to the diverse layout needs of chemical production. Equipped with an explosion-proof motor, it perfectly meets the explosion-proof safety standards of chemical workshops. It supports full-dimensional non-standard customization and can be equipped with rollers to facilitate equipment movement and workstation adjustments according to production conditions. It supports multi-point feeding and adapts to the powder transfer needs of various scenarios and batches in chemical production.
The Powder Screw Feeder Conveyor for Chemical Industry is suitable for powder transfer under various working conditions, supporting horizontal, inclined, and vertical multi-directional conveying. Its fully sealed structure prevents dust, ensures stable operation and easy maintenance, and easily adapts to all scenarios of chemical powder conveying.
Flexible Structure: Adopting a modular tubular design, it offers flexible installation methods, easily adapting to complex workshop spaces and traversing equipment and floors horizontally, inclined, or vertically.
Explosion-proof Safety: Equipped with a dedicated explosion-proof motor, it meets the explosion-proof safety standards of chemical workshops, avoiding the safety hazards of flammable and explosive materials during powder conveying from the power source, ensuring safe production operations.
Customization: Supports full-dimensional non-standard customization. Pipe diameter and blade parameters can be adjusted according to powder characteristics and conveying requirements. Roller designs can also be added for easy equipment movement and workstation adjustments.
Sealed and Leak-Proof: Utilizes a sealed tubular structure, ensuring zero powder leakage and dust generation throughout the conveying process, reducing material loss and preventing powder pollution of the workshop environment.
Designed for multi-condition conveying of chemical powders, the Powder Screw Feeder Conveyor for Chemical Industry consists of five core structures: a sealed tubular cylinder, wear-resistant spiral blades, an explosion-proof power transmission device, sealed inlet and outlet ports, and a frame base. An explosion-proof motor paired with a reducer provides stable power. The sealed tubular cylinder and inlet/outlet ports form a fully enclosed conveying space, preventing powder leakage and dust generation. The wear-resistant spiral blades are the core of the conveying process, driving the powder to complete multi-directional transfer. The frame base can be equipped with rollers for flexible movement. All components work together to ensure safe, high-speed, and continuous conveying of chemical powders.
Our factory manufactures three main types of Powder Screw Feeder Conveyors for the Chemical Industry: tubular screw conveyors, U-shaped screw conveyors, and flexible hose screw conveyors. These types differ in structure and characteristics, adapting to various chemical powder transfer conditions.
Tubular Screw Conveyor: Featuring a fully sealed tubular cylinder design, it offers excellent dust and powder leakage prevention. Suitable for flammable, explosive, and easily airborne fine chemical powders, it supports horizontal, inclined, and vertical multi-directional conveying. Available in carbon steel, stainless steel, and PP materials.
U-shaped Screw Conveyor: With a semi-open U-shaped cylinder structure, it is easy to clean and maintain. Suitable for low-viscosity, dust-free general chemical powders, primarily used for short-distance horizontal conveying. Flexible unloading makes it suitable for powder transfer at fixed workstations within a workshop.
Flexible Hose Screw Conveyor: Utilizing a flexible hose with built-in helical blades, the machine is lightweight and easily bendable. It supports the addition of rollers for mobile operation and is suitable for short-distance powder transfer in multi-station, irregularly shaped sites in chemical production, offering high flexibility.
The core working principle of the Powder Screw Feeder Conveyor for Chemical Industry is to utilize the mechanical thrust generated by the high-speed rotating helical blades within a sealed pipe to achieve forced, stable, and directional conveying of powder. When the motor drives the helical shaft to rotate at high speed, the blades propel the chemical powder entering the pipe forward axially, completing the powder conveying. Because the pipe is completely sealed and has a highly smooth inner wall, the powder does not come into contact with the external environment during conveying, effectively preventing the risks of moisture absorption, oxidation, contamination, or dust explosions. Its conveying speed is flexibly adjusted via a variable frequency motor.
