Drum Dryer, also called the drum drying equipment or Rotary Drum Dryer, is the most common and widespread drying mining equipment. It is suitable for processing the metal and nonmetal ores, clay in the cement industry and coal slime in the coal industry. It is characteristic of high productivity and easy operation.

Principle of Working:
The materials get into the drum from the charger through a gradient pipe. The rotating drum used to dry materials is put sloping0ly. Thus, materials from the high part get in touch with the heat carrier from the lower part. of course, there is a situation materials and heat carrier get in from the same part. along with the rotation of the drum, the materials will move forward to the lower part for the gravity of themselves. it is during the movement the material get the heat from the heat carrier direct or indirect. so, the wet material is dewatered.

Characters:
(1) Dryer is controlled by computer automatically. It is available to adjust the drying temperature and the drying time     according to particular drying requirement.
(2) The charger with large diameter makes it more convenient to feed materials into or out of the drum. In addition, it makes the slurry pl ing impossible and protects the duct clear. It greatly enhances the drying efficiency.
(3) High drying efficiency and low energy consumption.
