Professional Sawdust Drying Machine for Pellet Production Line

High Efficiency Airflow Biomass Wood Chips Rotary Drum DryerFeatures:Rational internal structure, high efficiency, and remarkable energy - saving. According to our inspecting result, the heat efficiency is about 85% more than traditional dryer.Cylinder self- insulation thermal efficiency can reach to above 70% (traditional single cylinder dryer heat efficiency is only 35%), so it can improve thermal efficiency at least 35%.Covers an area of 50% lower than single drum dryer and civil work investment can reduce 50%, power consumption reduced by 40%. In addition, The external cylinder has higher heat preservation and heat insulation effect ,so outer tube surface temperature is near to room temperature, it will not only keeps high heat energy utilizing efficiency , but also can improve the working environment and conditions. It can easily adjust the final moisture according to client's requirement. Low outlet temperature of dust collection system to keep clean working environment.Newdriving system. It adopts of tug wheel transmission without gear transmission. Motor adopts frequency controlling motor, and the rotating speed of cylinder could be adjustable according to the moisture, production capacity. Automatic temperature monitoring and controlling system, make operation more convenient.

Application of Sawdust Rotary Dryer:
The rotary dryercan be widely used in the following industries: straw press briquettes fuel, charcoal machinery, wood chip granule fuel, sawdust press blocks, farming and animal husbandry engineering industry;it is able to dry agricultural cellulosic-based materials such as: corn straw, soybean straw, cotton straw, wheat straw, sorghum straw, wood chips, wood shaving, sawdust drying, ginkgo leaf drying and mulberry leaves drying, etc.
How does the Sawdust Rotary Dryer Works?
The wet materials are conveyed to the hopper through the belt conveyor or bucket elevator, and then enter into the feed end through the hopper charger and the feeding pipe in sequence.The inclination of the feeding pipe must be greater than the natural inclination of materials in order to make the materials flow into the dryer smoothly. The dryer cylinder with slight inclination with the horizontal line.The materials enter from the higher end, and the heat carrier enters from the lower ender; the two contact each other from opposite directions, but there are also circumstances that the heat carrier flows into the dryer body together with the material.Along with the rotation of cylinder, the materials run to the lower end due to gravity. In the forward movement of wet materials in the dryer body, the wet materials are heated directly or indirectly by the heat carrier to dry the wet materials, and then the materials are discharged from the discharge end through the belt conveyor or screw conveyor.
