As a rule, the radiator in which the ambient air is heated is arranged distributed over the length of the dryer above the dryer belt. If a low-temperature circuit and a high-temperature circuit are used, the low-temperature circuit is arranged before the high-temperature circuit in the direction of air flow.

The housing of belt dryers consists of a steel structure which is insulated in the temperature-stabilized areas. The steel structure is arranged into feed station, delivery station and preferably identical center sections (modular construction). The space underneath the dryer should be designed to be as accessible as possible since chips must be removed from there quite frequently. It is not necessary to provide the entire dryer with weather protection but this is recommended so that maintenance work can also be carried out under weather protection and the material is protected. The stack or stacks or waste air ducts are mounted on the steel structure.

Figure 6.31 shows an example of a belt dryer.
