WASTE TO ENERGY
The GKD process belt
resistant to wear on the underside due to its fl atness. With air permeability of 4,300l/m²/s optimally tailored to the drying process and a CFM value of 660, it ensures an effi cient drying process despite the very closed surface. At the same time, the smaller number of direct apertures resulting from the weave type reduces dust ingression. T e belt also stands out with dimensional stability up to 200°C and resistance to chemical infl uences up to a pH-value of 14. “It is simply a reliable belt

that served us well for seven years,” says Jakob Friedrich, CEO of TEAtherm, in praise of the fi rm’s fi rst experience with the GKD belt. He adds: “We know from other system operators that some of them have to replace their belt every year.”
ALL-IN SERVICE WITH PERFECT TRAINING
When a tear appeared in the belt in its seventh year of use, TEAtherm wanted to fi t a spare GKD belt they had found at the power station. However, mechanical engineer Friedrich and his team lacked the necessary experience and so asked GKD for help, which was promptly delivered. T e fi tter sent by GKD was on site for two days to fi t the replacement belt and train the TEAtherm team in how to fi t the belts. He didn’t know that Friedrich had joined the team so that he could see the process for himself. “If you want to form a valid opinion as an engineer, you look at things yourself and join in with the work so you know what works and what doesn’t when you’re in contact with your co-workers,” explains
Friedrich. GKD supplies these process belts with a specifi c unrolling function in the transport crates. T is makes it possible for the heavy belt to be pulled

into the machine directly from the crate with a special belt feeder and straps. T is not only enables energy-saving fi tting without the need for a crane, but is also gentle on the material, as the belt is not pulled accross the fl oor into the dryer. “T e GKD employee performed the replacement brilliantly with our staff and generally provided us with very good support,” says Friedrich. He was so impressed with this dedication and service that he ordered a new belt right away. T is support proved its value after just
a year. T e spare belt found by TEAtherm turned out to be a used belt, which itself had to be replaced. “We fi tted the new belt ourselves without any problems,” says Friedrich, who attributes this success to the high-quality training service from GKD. T e 5099 PPC also meets TEAtherm’s specifi c requirements for a dryer belt in every respect. T anks to its low wearability with process-specifi c air permeability, tear resistance to contaminants, and long service life, it guarantees an effi cient drying process in the long term. T at’s why the company immediately ordered a new spare belt,
as Friedrich’s opinion of the process belt and GKD is thoroughly positive: “Fast delivery, reliable belt, and a service we can rely on.” Perfect conditions for the planned capacity expansion in sewage sludge drying.
