The dryer machine is widely used to dry most kinds of materials in the industrial, agricultural production as well as to dry the wet concentrate at the end of the industrial mineral processing production. As a device that removes the moisture of the materials, a dryer can turn the materials with much humidity into those with little moisture.

The three-cylinder dryer, as a more energy-saving and higher efficient device among so many drying machines, is improved based on the single cylinder dryer to be applied by many entrepreneurs and industries for good reflection. The energy-efficient three-cylinder dryer has a reasonable design with three layer structure inside. Materials can exchange heat with hot airflow through the radiation, the convection and the conduction inside the cylinder. Outside, the heat exchanges by both the convection and conduction effect. It is tested that the three cylinder dryer has much higher thermal energy efficiency than the traditional one.

The performance of the three-cylinder dryer has been praised by customer s all over the world and it has been famous for its following features:

1. Little investment capital which occupies only one sixth of the foreign imports.

2. As a premier choice for the mineral slag production line, it can guarantee the humidity of the materials below 0.5%.

3. The cylinder can preserve its heat as much as 70%.

4. It takes fewer areas and costs less power than the single cylinder dryer.
