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 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, KÖLLEMANN 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 KÖLLEMANN self-cleaning principle, problem-free conveying is possible, even for adhesive bulk materials. Our portfolio offers you suitable screw conveyor products for all areas of application.
- Length without middle bearing up to 14,500mm
- Diameter from 100mm to 1200mm
- Single or multiple shaft design
- Tubular or U-shaped trough
- Shaft geometry adapted to the bulk material
KÖLLEMANN feeding-screw conveyors are used to fill 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 the field of conveying we have many possibilities for designing the geometry and configuration of the system: 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 machine, 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.
- Direct input into fluidised bed furnaces
- High-temperature resistance
- Optional structure cooling
- Bearings on one side only
