Electric Hose Screw Conveyor
Friday December-19 2025 13:18:53
The Electric Hose Screw Conveyor seals rotating helical blades within a wear-resistant, flexible hose. Driven by an external electric motor, it axially propels materials within the hose. Hose diameters are available in 50mm, 76mm, 102mm, 127mm, and 200mm, with conveying capacities ranging from 1 cubic meter to 30 cubic meters per hour depending on configuration. Electric motor power typically ranges from 0.55kW to 5.5kW. The hose is made of highly wear-resistant and corrosion-resistant polyurethane or special rubber composite materials, while the internal helix is made of high-strength spring steel or stainless steel. This equipment is commonly used to convey free-flowing, dust-prone, and tightly sealed powdery, fine granular, or small lump materials.
Electric Hose Screw Conveyor Structure
The Electric Hose Screw Conveyor consists of a pure copper core motor, thickened reinforcing tubing, double-shaft pulleys, casters, a fully open material bin, and an auger. The electric motor provides power for the equipment's operation, the flexible hose forms the material conveying channel, and the dual-shaft pulleys ensure smooth power transmission and speed control. Casters facilitate free movement and position adjustment within the workshop, and the fully open foreign object bin facilitates the removal of blockages or foreign objects. The auger continuously conveys materials while preventing backflow or blockages.
Advantages of the Electric Hose Screw Conveyor
The Electric Hose Screw Conveyor can be installed horizontally, inclined, vertically, or even around obstacles. Its minimum bending radius can reach 4-6 times the equipment diameter, adapting to existing production line upgrades. Materials move within a closed pipe, preventing dust emissions and reducing material loss, keeping the surrounding environment clean. Compared to pneumatic conveying systems, its energy consumption is typically 30%-50% lower, requiring only the drive screw to rotate, eliminating the need for large power sources such as air compressors or vacuum pumps. The electric motor can be controlled to start, stop, and rotate, and the conveying capacity can be adjusted according to site conditions, making it very convenient to use. The screw smoothly pushes materials with low shear force, reducing damage to fragile or crystalline materials.

Comparison of Electric Hose Screw Conveyor with Other Equipment
Compared to rigid screw conveyors, the Electric Hose Screw Conveyor offers more flexible layout and better material protection, but it is less adaptable to oversized lumps or highly abrasive materials. Compared to pneumatic conveying systems, electric hoose screw conveyors offer faster conveying speeds but higher energy consumption, more dust, and require complex piping designs. Flexible hose screw conveyors provide stable, low-speed transport, are energy-efficient, and produce less dust. Vacuum conveyors have limited conveying distances and are prone to clogging with particulate materials, while flexible hose screw conveyors offer flexible conveying distances and a lower risk of clogging.
Electric Hoose Screw Conveyor Suppliers
In the domestic and international markets, manufacturers of electric hoose screw conveyors include Flexicon (Germany), Conveyor Systems (USA), and Dahan Machinery (China), among others. German and American manufacturers excel at providing standardized modules and high-end customized solutions. Dahan Machinery manufactures a wide variety of equipment and offers personalized customization and motor type options, with more competitive pricing compared to European and American companies.
The price of an electric hoose screw conveyor typically ranges from $700 to $9000, varying depending on factors such as hose length and motor type. During installation, determine the equipment location and conveying route, fix the support frame, connect the flexible pipe to the inlet and outlet, install the motor and connect the power supply, conduct no-load testing to confirm steering and smooth operation, and finally conduct a material loading test. When selecting a supplier, if you can provide information such as the working scenario and conveying capacity, the supplier will provide the motor configuration and pipe diameter and length to match the requirements.
