Roller Dryer Should Advance with New Technology

The roller dryer is a kind of dryer machine with continuous operation which can be directly contacted. The roller dryer is composed by a cylindrical housing with slow rotation. The housing is inclined. There is a smaller angle between the housing and the level in order to facilitate the transport of the wet materials. The materials enter the rotary cylinder from the high end. The products dried discharge from the low end. In order extend the residence time of the fine and light materials in the roller dryer, the discharging end of the inclined cylinder should be raised.

The roller dryer is mainly used for drying the materials with certain moisture in mineral processing, building materials, metallurgy, chemical industry and other departments. The drying machine production line is mainly composed by the rotating cylinder, cited wind equipment, high-speed scattered equipment, lifting plate, self-cleaning device, transmission, transport equipment, hot air equipment, reducer, supporting device and the sealing device component. The complete drying equipment produced by Henan Hongxing Mining Machinery has the advantages of reasonable design, perfect workmanship, stable performance, advanced technology, high production, low energy consumption, small power consumption, small floor area and high mechanical degree. The drying media (hot air, gas, flue gas) flows with the materials and passes the cylinder along the axial direction. When the materials have no thermal sensitivity or the materials are required to be dried to very low moisture, the countercurrent flow is often used. The current flow type is often used to the drying process of the materials with thermal sensitivity and the high dehydration rate. 

The flue gas produced by the oil fuel, gas, coal and the stove is the drying heat source medium. When the wet plaster is sent to the screw feeder through the transport hoist and enters the roller dryer, the plaster contact with the hot air. With the rotation of the roller dryer, the materials to be dried move forward along the inner wall of the drying room with the action of the induced air. The roller dryer produced by Henan Hongxing Mining Machinery can maximize the utilization of energy and reduce the floor space through rich experience and continuous improvement.
