Amandus Kahl

Compacted and dust-free municipal and industrial sewage sludge can be treated further at low costs. KAHL sewage sludge pelleting provides:

• Easy transport,
• Use as cover material in landscaping,
• Well-suited quality for thermal utilisation.

Our system including the KAHL flat die pelleting press is particularly appropriate for sewage sludge. It can be adapted to varying percentages of organic matter and different pH-values without any problems.

After an appropriate pre-treatment, the solid content of the sewage sludge is between 60 and 95 %. By means of the pan grinder rollers it is ground and compacted on the die. The bulk density of the pellets is about 800 kg/m³.

Powerful and long-lived

The pelleting elements have a service life of 1,500 - 2,000 hours, thus allowing fully automated unsupervised plants to operate for periods of about three months until the next maintenance.

Safety regulations do not cause any problems. At a maximum possible circumferential speed of 2.5 m/s and operating temperatures below 120 °C there is no danger of fire in the plant.
