METHOD AND MACHINE FOR DRYING MATERIALS

摘要

A method and a drying machine for drying materials, for example foundry sands, laundry, chemical pulps and/or bulk materials. The materials to be dried are loaded into a drying container, in which liquid is vaporized. The steam produced is passed into a condensation chamber and condensed there in thermal contact with the material from the drying container. In this way, the heat of condensation can be recovered for a renewed vaporizing process. The drying machine may be used in particular in a regeneration plant for inorganically bound foundry sands.

主权项

1. A drying machine for the drying of materials, for example of foundry sands, laundry, cellulose materials and/or bulk materials, containing:
a drying container for receiving the materials; and a condensation chamber which is connected to the drying container and in which steam can be condensed out of the drying container in thermal contact with the material of the drying container, the drying container containing a rotatably mounted drum dryer, and the condensation chamber being connected firmly to the drum dryer.
