Cooling Screw Conveyor

High-Efficiency Bulk Material Cooling with KÖLLEMANN Technology

The KÖLLEMANN Cooling Screw Conveyor is a robust and efficient solution for cooling a wide range of bulk materials and pasty media. Designed for industries where careful product handling and strict separation of cooling medium and bulk product are essential, our cooling screw conveyors ensure maximum reliability and performance.

These systems are used across multiple industries for products such as:

• Bottom ash & fly ash
• Sewage sludge & cement
• Salts & plastics
• Pyrolysis waste & cyanide
• Adhesive or pasty bulk materials

Wide Temperature & Application Range

With a temperature resistance of up to 1,200°C, our cooling screw conveyors are suitable for even the most demanding environments. Active cooling of all product-contact surfaces ensures:

• Long service life
