Mobile Stainless Steel Screw Conveyor is a continuous conveying device that uses rotating helical blades to propel materials. Its position is adjusted via bottom casters or a support structure. It is suitable for horizontal and inclined conveying of powdery, granular, and some small lump materials.
Material: 304, 316 stainless steel
Pipe Diameter: 110-300mm
Angle: 0-90°
Length: 2-15 meters
Applicable Materials: Grains, flour, seasonings, yellow corn, lime powder
Mobile Stainless Steel Screw Conveyor is a new type of conveying device that combines conveying functionality with ease of movement. It utilizes rotating helical blades to continuously push and convey materials along a closed pipe or U-shaped trough, achieving horizontal or inclined material transfer. The main body is constructed from 304 or 316L stainless steel, offering excellent corrosion and wear resistance, as well as easy cleaning. Whether handling powdery, granular, or small lump materials, it operates rapidly in a sealed environment, effectively suppressing dust and improving the working environment.
The Mobile Stainless Steel Screw Conveyor features a compact and functional design. Its core components include the tube body, blades, motor, hopper, and casters. The tube body, as the enclosed material conveying channel, provides support and guidance, and its airtightness effectively prevents material leakage and dust emission. The blades, welded to the rotating shaft, are the core working elements, converting the rotational motion of the material into axial linear propulsion through their helical surfaces. The motor, as the power source, provides the driving force for the rotation of the screw shaft, ensuring the material moves forward against friction. The hopper, located on the upper side of the lower end of the tube body, is used for temporary storage of the material to be conveyed, facilitating even feeding. The casters at the bottom are a key distinguishing feature between the mobile and stationary versions.
The Mobile Stainless Steel Screw Conveyor works based on the rotating and pushing action of a screw. When a motor drives a shaft with helical blades to rotate within a closed tube, the material fed into the hopper, under the influence of its own gravity and the friction of the tube wall, does not rotate with the blades but is continuously pushed forward by the rotating helical surface. This forced propulsion method allows the material to move smoothly along a set path from the inlet to the outlet, completing the conveying task.

Multi-functional: Equipped with casters for flexible relocation, one machine can serve multiple workstations, completely eliminating the need for redundant equipment purchases. The stainless steel body is corrosion-resistant and easy to clean, meeting food and pharmaceutical-grade hygiene standards, while significantly reducing manual handling intensity and dust pollution.
Reduced Equipment Procurement: Traditional stationary conveyors are immobile once installed. When multiple workstations or silos require material supply, several units often need to be purchased. Mobile conveyors, with their flexible casters, can serve multiple locations with a single unit, achieving multi-purpose functionality.
Adaptability to Regional Changes: Mobile screw conveyors can be adjusted to accommodate temporary changes in production processes, the construction of new pilot lines, or optimization of equipment layouts, without the need for complex disassembly or civil engineering modifications.
Meeting Hygiene Requirements: For industries such as food, pharmaceuticals, and fine chemicals, equipment not only needs to be corrosion-resistant but also easy to clean and pollution-free. The stainless steel body effectively resists material corrosion, and its smooth surface prevents dirt accumulation, ensuring the conveying process meets stringent hygiene standards.
Reduced Manual Handling: It can be quickly integrated with mixers, packaging machines, and other equipment to achieve mechanized and automated feeding, significantly saving labor costs and improving operational efficiency.
Mobile Stainless Steel Screw Conveyors are widely applicable and ideal for conveying various powdery, granular, and small lump loose materials. Thanks to the corrosion resistance of their stainless steel construction and their sealed design, they are commonly used in the chemical industry for transporting fertilizers and soda ash, in the food industry for grains, flour, and condiments, and in the building materials industry for transferring cement and ash.
However, screw conveyors are not recommended for certain materials. Because they rely on helical blades to propel materials forward, easily perishable, highly viscous, or easily agglomerated materials can adhere to the blades and pipe walls, causing blockages and severely impacting conveying efficiency. Furthermore, for highly abrasive or large, hard materials, the helical blades will experience severe wear; unless specially treated for wear resistance, their use is not recommended.
