Lifter plates | Dryer and recycling drums

The dryer drums are the key components in the asphalt production process, both for the white mineral and the RAP material. They remove moisture from the raw material and perfectly prepare the material for the processing temperature.

The drums are available in different lengths, diameters and with different built-in materials depending on the system design and the drying matrix (based on the burner, dryer drum, and dust collection).

Influencing parameters such as the plant location, type of rock, material moisture, material temperature and fuel type determine whether lifter plates are used.

Dryer drums are compact, robust and easy to maintain. Made by Benninghoven.
