Application
The three drum rotary dryer is a machine designed based on upgrades to the single drum rotary dryer. It dries materials in the form of lumps, granules, and powders as long as the material diameter is under 20mm. Compatible materials include slag, clay, coal, sand, etc. Three cylinder rotary dryers can be the ideal choice when looking for auxiliary equipment for mixed mortar and slag production lines widely used in building materials production, chemical processing, and foundry applications.

Applicable materials
The materials which can be dried by the three drum rotary dryer are mixed mortar, sand, slag of cement plants, clay, coal, mixture and iron powders.
