The drum dryer has the advantages of large output, easy operation and wide application range. It is widely used in building materials, metallurgy, minerals, chemical industry, etc. It is mainly used for materials with high wetness and high specificities such as slag, limestone, clay, river sand, quartz sand, and water slag. Because the material is constantly tumbling in the drum, it is more suitable for those materials that do not have many requirements for the shape, color and smell of the final product.

In the tumble dryer, the material is continuously thrown, turned, and dropped under the action of the high-speed rotating blades and the material board, and at the same time, it has sufficient contact with the high-temperature hot air to carry out strong convective heat exchange, to realize the efficient drying of materials.
