Rotary Grain Dryer/Grain Rotary Drum Dryer/Rotary Drying Machine is called drum dryer, drying plant, and drying machine . Rotary drum dryer can be seen in many industries. Because it is only a carrier, its thermal power is provided by the outer hot air to dry the materials. It has features like big processing capacity, simple maintenance and long service life.
Applications of Rotary Grain Dryer
Rotary grain dryer is used widely to dry construction sand, abandoned tailings, new energy material, ore, powder and coal. The dry selection shall consider the local fuel, place and environmental protection.
Working Theory of Grain Rotary Dryer
the wet material is taken to the hopper by belt conveyor or bucket elevator, and then the material goes into feed opening through feed pipe with the help of feeder. The slope of the feed pipe shall be higher than the material’s dip angle to make the material flowing into the dryer drum. The dryer drum is a rotary drum and there is a slight slope between the drum and the horizontal line. The material is fed through the higher end, and the heat carrier goes from the lower end, which forms an upstream contact with the wet material. During the movement in the drum, the material gets the heating directly or indirectly, and then is dried. Later the dried material is transferred by the belt conveyor or spiral conveyer at the discharging opening. There are lifting boards on the inside wall, which lifts and scatters the material to make the contact surface bigger between the material and the heat carrier. This can promote the drying rate and push the material forward. Heat carrier is usually hot air or flue gas. After go through the dryer, the substances containing in the heat carrier usually need to be collected by cyclone dust collector. If the air dust content need to be reduced further, bag filter or wet dust remover shall be used.
