Screw conveyor

KOELLEMANN screw conveyors are used to convey dusty, granular, flowing and semi-moist bulk materials. Their strengths are best used with free-flowing and conveyable materials such as sand, cement, granulate, ash and similar materials.

However, our screws are also perfectly suitable for conveying problematic bulk materials such as potentially explosive, abrasive or adhering materials.

We supply screw conveyors to meet the needs of many industries, such as chemical and plastic, food and feed, minerals processing, wood products and wastewater treatment.

The screw conveyors are available in a wide range of sizes, lengths, configurations and materials of construction.
We will be pleased to help you to solve your conveying problems or to convey your goods.

Thanks to sophisticated engineering and our wealth of experience, KOELLEMANN screw conveyors are an obvious choice, even for products that under normal circumstances could hardly be dealt with by a screw.

Thanks to the proven and tested KOELLEMANN self-cleaning principle, problem-free conveying is possible, even for adhesive bulk materials. We can offer screw conveyors in various models for different applications:

Range of screw conveyors:

  • Pipe screw conveyor
  • Trough screw conveyor
  • Multiple shaft screw conveyor
  • Feeding screw conveyor
  • Cooling screw conveyor
  • Heating screw conveyor
  • Self-cleaning screw conveyor

 

Screw conveyor technical data:

– Length without middle bearing up to 14.5 m (with middle bearing up to 60 m)
– Diameter from 100mm to 1200mm
– Single or multiple shaft design
– Tubular or U-shaped trough
– Shaft geometry adapted to the bulk material

Our screw conveyors are assembled, commissioned and maintained worldwide by trained expert personnel. Long years of experience with a variety of products ensure that the system is quickly and safely serviced.

For decades, our screw conveyors have been used to transport the widest range of bulk materials under
the hardest environmental conditions.

Our screw conveyors are designed as a modular system with many variants to suit the task in hand, planned, produced and assembled for the purpose.

Feeding-screw conveyors

KOELLEMANN feeding-screw conveyors are used in the wide range of application such as filling combustion chambers, calcining furnaces, fluidized bed systems and waste incineration plants. Even if the process conditions will not allow a bearing to be used at the end side (facing the process), charging screws are the optimum solution.

Thanks to our longstanding experience in this segment we have many possibilities for designing the geometry and configuration of the screw conveyors: For example, it is possible to cool or – if the process requires – to heat individual parts or the entire machine to protect and maintain the structure.

Abrasive bulk materials do not pose a risk to the life of the screw conveyor, as the varied options provide effective measures for preventing unwanted premature wear. Our product range includes versions with multiple shaft designs to satisfy the mass flow rate and cleaning requirements.
