It is obvious to all that drying machines develop rapidly and are well-received among the global markets. As its name implies, the coal slime dryer is used to dry coal slime. The finished products can be applied for boiler use in power plant. Starting from the point of saving energy and reducing emission, Fote produces the newly-type coal slime dryer. With remarkable advantages of low consumption, stable performance and wide application ranges, Fote coal slime dryer adopts the advanced technical process of heat transfer from Germany.

Drying process happens in the state of high humidity. Since the temperature of feeding mouth is about 430℃, heat transfer happens immediately between hot air and coal slime. Since the three-level drying area of coal slime dryer is normal drying area with temperature about 120℃-210℃, the surface of coal slime is not easy to be coked. While, four-level drying of coal slime dryer is to dry coal slime with hot air in negative pressure under the influence of induced air.

The newly-type coal slime dryer would produce relatively large peripheral force on low-speed gear. Thus, users should pay much attention to the influences of large speed ratio and high pulling torque. Physical or chemical changes in coal slime dryer should be dependent on the factors of raw material and fuel, etc. Fote sincerely reminds that users should choose a motor with large torque. since during the working process of coal slime dryer, not only does the friction torque between roller axle and bearing needs to be controlled but also the inertia moment between rotary drum and coal slime.
