Screw conveyors for recycling waste

Screw conveyors for recycling waste designed and manufactured for a customer that builds complete recycling plants. The tubular screw conveyors transport the recycled waste internally in the recycling process plant.

Why are screw conveyors well suited for transporting recycled material?

1. The screw conveyor is a completely closed machine. You reduce dust and other emissions to the environment
2. Screw conveyors have a long life time, and there is only one moving part – the screw auger
3. They are easy to install on-site, and assembly time is reduced

BEMA has worked closely together with the customer to optimize the screw conveyors for a long lifetime and being easy to install. See another example of a screw conveyor for recycled material here

How is BEMA working with the customer to optimize the design of screw conveyors

1. BEMA checks the capacity calculation of all screw conveyors manufactured
2. BEMA supervise the customer to use the right size of gearmotor/gear box
3. BEMA design in- and outlets for easy installation on-site

A screw conveyor is typically customer designed since it has to fit in exisiting machineries or buidlings. If the design is correctly done towards the function and installation,  the solution is fully comparable to use standard equipment. Furthermore standard equipment are seldom workable to a specific application that often requires specific types of steel material and other specific components. A large part of BEMA’s products are used in the recycling industry.

Example of recycling materials that can be transported in a screw conveyor

1. Mineral wool
2. Gypsum waste
3. Sludge
4. Fractions from recycling of cables, refrigerators, electronic equipment etc.
5. Glass
6. Paper
7. Crushed concrete

BEMA has its own technicians and design engineers that can assist in design and planning of a screw conveyor project. We always recommend to contact us early in the design process, so we can help to optimize the complete solution.

FAQ – Screw Conveyors for Recycling Waste

1. Why are screw conveyors well‑suited for transporting recycled materials?

Screw conveyors are ideal for recycling environments because they operate as fully enclosed systems, which significantly reduces dust and emissions during transport. This containment improves workplace safety and environmental performance. With only one moving part—the screw auger—they offer long service life and low maintenance demands. Their compact design also makes them easy to install in existing recycling lines, even where space is limited.

2. How does BEMA optimize screw conveyors for recycling applications?

BEMA collaborates closely with customers to ensure each conveyor is designed for durability, efficiency, and easy installation. The team verifies capacity calculations, advises on the correct gearmotor or gearbox size, and designs customized inlets and outlets to simplify on‑site assembly. This tailored approach ensures the conveyor fits seamlessly into existing machinery or buildings while meeting the functional requirements of the recycling process.

3. Are screw conveyors standardized or custom‑designed?

Most screw conveyors for recycling are custom‑designed. Recycling plants often require specific materials, geometries, or wear‑resistant components that standard equipment cannot provide. When designed correctly, a custom conveyor performs as reliably as standard equipment but with the added benefit of being optimized for the exact application and installation conditions.

4. What types of recycled materials can be transported in screw conveyors?

Screw conveyors can handle a wide range of recycling materials, including mineral wool, gypsum waste, sludge, glass, paper, crushed concrete, and fractions from cable, refrigerator, and electronic waste recycling. Their versatility makes them a core component in many recycling plants.
