The machine is for drying granular materials within a certain humidity scope, for example, yellow sand in dry mortar industry, all kinds of sand in foundry industry(such as, river sand, quartz sand), slag in cement industry, clay ect. raw materials, widely used in building materials, chemical industry, small particle size casting, etc.. According to the requirements for final moisture after drying materials in different industries, the material moisture after drying can get to less than 1-0.5%.
It can burn a variety of fuels such as coal, oil, gas

The Efficient-combined three-cylinder dryer have a lot of advantages, for example,compact structure and less land occupation(just 1/2 needed area of single cylinder with the same production), reliable operation, low energy consumption, high thermal efficiency, good material drying effect, easy to realize automation control, less operators.
