More than 1000 KAHL belt units are in operation worldwide and work in different sectors. Before you decide on a belt drier, you have the opportunity to perform a belt drier simulation for your project in our pilot plant. Both cooling and drying are carried out according to the cross and counter current principle, depending on the number of belts. Due to the modular design of the belt units, they can be optimally combined to meet the required plant size. They are designed to suit both small and large units according to the modular principle. Cooling: Belt units used for cooling operate according to two physical processes: Convection cooling provides heat exchange between product and air. Evaporation cooling on the other hand removes water from the product. The ambient or cooled air passes through one or more product layers and is used for all products with unlimited moisture levels that must be cooled to a low storage temperature. These include, for example, feed concentrate pellets, expanded products, dried beet pulp pellets, plastic waste or graphite. Drying: In order to achieve optimum and particularly gentle drying of your product, hot air flows through the product from the top or from the bottom. The process air heated directly or indirectly up to 200 °C passes through one or more product layers. It is particularly suitable for products with high moisture levels that may be discharged at high temperatures (e.g. cat litter, charcoal briquettes, filter sludge or metal oxides).
