Three Cylinder of Single Drum Dryer for Sawdust

Three Cylinder of Single Drum Dryer for Sawdust

【Application】widely used to drying many material, such as wood chips, sawdust, bean dregs, slag,sand, coal slurry and other materials
【Capacity】44-260 ton/ day
【Motor】28-135 kw
【Drying temperature】250-350 ℃

DLSG three cylinder of single channel drum dryer is a new type of rotary drum dryer, adopt unique technology, compared with the traditional drum dryer, under the same output can save one third of the energy consumption of fuel, is popular among the masses of users.At present it has been widely used in food, feed, chemical industry, medicine, fertilizer, etc.According to the requirement of the drying products, can use different heat source, such as: straight hot stove, indirect furnace, heat conduction oil, electric heating, etc.Drying of this machine is suitable for a variety of materials such as wood alcohol, liquor worse, worse, pomace, medical, tea leaves, bean dregs, sugar, starch, potato slag slag slag, straw, corn cobs, leaves, coconut shell, etc., it can create a feed, energy resources and has a good effect in reducing the  environmental pollution.

Three cylinder of single channel drum dryer characteristics:
1.It can realize intelligent control, a key "fool" type operation, the operation parameters of automatic control, the dryer is always in the best condition to run in order to ensure stability of the wood moisture,and more energy efficient than traditional dryer.
2.Automatically remove the impurities ,deferrization , make sure the impurity not go into the process after the drying of wood.
3.Cylinder self insulation thermal efficiency can reach above 70% (traditional single drum dryer heat efficiency is only 35%), it can improve thermal efficiency by 30%.
4.Adopt four-wheel drive,driving is more stable and reliable.
5.Covers an area about 50%,which is lower than single drum dryer ,and civil investment reduced by about 50%.
6.The internal structure of the dryer are combined by various efficient feed plate modes, effective regulation of drying process and heat distribution, high heat utilization,waste gas discharge temperature is lower than 50℃.
7.Adopts frequency control of material flow,it can easily control the final moisture indicator according to the customer's requirements.
8.Using Modular dust collecting,dust purifying and heat recycling configuration,safe environmental protection.
9.With many kinds of new type energy-saving hot blast stove, high efficiency and energy saving, heating control, simple operation, energy consumption dropped about 30%, 20% lower power consumption, lower operating costs.

Production process and technical parameters:
Material process is:shatter sawdust with 35-45% moisture are sent by belt conveyor to the drum through downstream drying, material under the copy board of inner grabbed, scattered in a spiral type marching forward constantly, through inner, middle and outer layer, realize heat exchange between materials and hot air , the materials through drying discharge fast under the effect of the wind, the wet material which not achieve drying effect can't move forward rapidly because of the weight . the material within the control schedule realize fully drying, thus achieve drying effect, finally the material moisture reduced to 12-15%, complete the drying process, the final product are discharged by the screw conveyor.Shaking cleaning devices are installed inside the drum to prevent material splice with cylinder wall.
Gas flow is: after the blast blower air pressure into the hot blast stove burning heat, the temperature amounts to 500-550 ℃, the induced draft fan inhaled the after-drying material, moisture evaporation, temperature down to 50-65 ℃ and then discharger from the dryer, dust moisture after a cyclone dust collector, wet precipitator purification discharging beyond standard.
