Spirotech Screw conveyor

• Transporting bulk powders and granules in food processing.
• Moving aggregates and dry materials in construction.
• Conveying grains and feed in agricultural settings.
• Handling waste products in environmental applications.
• Feeding ingredients into mixers or packaging lines.

Typical throughput

Throughput for this class of equipment typically ranges from a few hundred kilograms to several tonnes per hour, depending on material density and screw design.

Screw diameter

Commonly found screw diameters for industrial units range from 100mm to 600mm, influencing material volume per rotation.

Screw length

Screw conveyors are typically available in lengths from 1 metre to over 10 metres, often modular for extended runs.

Material of construction

Units for food and pharmaceutical applications are typically constructed from stainless steel (e.g., 304 or 316 grade) for hygiene and corrosion resistance.

Power supply

Industrial screw conveyors commonly operate on 3-phase electrical power, with motor sizes typically ranging from 1.5 kW to 15 kW depending on length and load.

Maintenance requirements

Regular maintenance typically involves checking bearing lubrication, motor function, and ensuring the screw flights are free from wear or build-up.

• What types of materials can a screw conveyor handle?

  Screw conveyors are well-suited for a wide range of dry, free-flowing to semi-fluid bulk materials, including powders, granules, flakes, and small lumps. Materials that are sticky or prone to bridging may require specialised designs.

• Can this type of conveyor transport materials vertically?

• What are the benefits of using a screw conveyor over other conveyor types?

• Is a used screw conveyor a good investment?

• What should I consider regarding installation?

Buyers typically value conveyor systems for their reliability and longevity when well-maintained. Key considerations when purchasing used units include belt condition, motor functionality, frame integrity, and available spare parts. Industry sentiment emphasises the importance of verifying operational history and cleanliness standards, particularly for food handling applications. Common strengths include robust construction, relatively straightforward maintenance requirements, and cost savings versus new equipment. Reputable manufacturers' models tend to hold their value well and integrate readily into existing production lines.
