KAHL sewage sludge pelleting provides:
- Easy transport
- Use as cover material in landscaping
- Well-suited quality for thermal utilisation
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.
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.
