Tubular Screw Conveyor For Metal Scrap is a closed conveying device designed for transporting metal scrap. Its overall tubular, sealed structure effectively prevents material leakage and dust spread. A single unit can convey up to 30 meters horizontally. The body material can be selected from carbon steel or stainless steel to suit various corrosion-resistant and wear-resistant applications. It can achieve vertical, horizontal, and inclined multi-angle conveying and supports non-standard customization for various working conditions, adapting to diverse metal scrap conveying needs and helping enterprises achieve automated material handling.
Based on differences in their core structures, the Tubular Screw Conveyor for Metal Scrap is mainly divided into two types: shafted and shaftless. The two types differ in structural characteristics and applicable material scenarios, allowing for flexible selection based on the shape of the metal scrap, its entanglement characteristics, and the conveying conditions.
Shafted Tubular Screw Conveyor: The core structure includes a central drive shaft and helical blades. The shaft drives the blades to rotate and push the material. With its strong structural rigidity and stable transmission, this conveyor is suitable for transporting metal scrap with regular particle size, small block size, and low entanglement, such as metal granules and small metal stamping scraps.
Shaftless Tubular Screw Conveyor: Utilizing an integrated shaftless screw belt to push materials, it avoids the problems of shaft entanglement and jamming. It is particularly suitable for long, filamentous, and highly entangled metal chips and shavings-like metal scrap.
With its enclosed structure, flexible layout, and customizable design, the Tubular Screw Conveyor for Metal Scrap offers multiple practical advantages in metal scrap transportation scenarios, balancing environmental safety, stable operation, and economic efficiency, adapting to various metal scrap transfer conditions.
Enclosed and Clean: The fully enclosed tubular structure prevents waste spillage and metal dust leakage during metal scrap transportation, avoiding environmental pollution and safety hazards in the workshop.
Flexible Arrangement: Can be arranged horizontally, inclined, or vertically; single unit can be up to 30 meters long horizontally; non-standard customization is supported; carbon steel and stainless steel materials are available to handle various working conditions such as wear resistance, rust prevention, and corrosion resistance.
Simple Structure: Fewer parts, stable operation, and low failure rate; shaftless models are anti-winding, while shafted models have strong load-bearing capacity, adaptable to different shapes of metal scrap.
High Adaptability: Can be connected to production lines and scrap recycling systems, providing continuous and stable conveying, reducing manual handling costs, and improving the efficiency of metal scrap recycling and transportation.
The Tubular Screw Conveyor for Metal Scrap relies on a drive motor to drive a reducer, transmitting power to the screw. The screw rotates within a closed tubular shell. The rotating screw blades generate axial thrust, smoothly pushing the metal scrap entering the inlet along the inside of the tube to the outlet for discharge.

Metal scrap comes in various forms and has diverse conveying conditions. Different companies have different requirements for output, conveying distance, and layout. We customize suitable screw conveyors based on the customer's usage scenario.
Machinery Manufacturing Plant: Primarily produces engineering machinery parts, generating a large amount of iron filings and steel cutting waste during production. A carbon steel shaft-tube screw conveyor is selected, with a horizontal conveying length of 28 meters. The equipment adopts a horizontal layout, with a designed conveying capacity of 8t/h, connecting to the machine tool scrap collection bin and centralized scrap storage area.
Scrap Metal Recycling Plant: Needs to transfer crushed copper and small metal granules after recycling and sorting. A non-standard customized carbon steel shaft-tube screw conveyor is purchased, using a combination of horizontal and small-angle inclined conveying. The horizontal section of a single unit is 12 meters long, with an overall designed conveying capacity of 12t/h.

We provide technical support and installation guidance to ensure the stable operation of your conveying system.
The selection of a Tubular Screw Conveyor for Metal Scrap requires comprehensive consideration of the material shape, conveying distance, working environment, and capacity requirements. It is also necessary to differentiate between shafted and shaftless models, rationally select carbon steel and stainless steel materials, determine the conveying angle based on the installation scenario, and customize equipment parameters as needed to select the appropriate conveying equipment.
For powdery and fine particles: GX or LS type shafted screw conveyors are recommended, with a smaller screw pitch to ensure stable and controllable flow rate.
For mixed debris: Shaftless screw conveyors are recommended. They have high torque, are less prone to shutdown due to blockage, and typically have a conveying capacity 1.5 times higher than shafted conveyors of the same diameter.
For sticky, oily waste: Attention needs to be paid to the power configuration of the drive unit. Although screw conveyors are traditionally considered unsuitable for conveying highly viscous materials, they can still achieve smooth conveying of waste containing cutting fluids from metal processing through proper design of the rotation speed and blade clearance.
The Tubular Screw Conveyor for Metal Scrap perfectly solves the problems of high wear, leakage, and blockage during the transfer of metal scrap through a closed and environmentally friendly conveying method, a robust and wear-resistant structural design, and flexible layout options.
