Working process of Cheap of rotary drying kiln for biomass fuel dried machinary series

First, the materials transferred into the inner rotary drum by the the feeding machine and achieve downstream drying, in the inner constantly took a copy board, by scattered spiral traveling type to do heat exchange;  

Then move to the other end into the middle inner do countercurrent drying is repeated bring out and in constantly in the middle by two steps forward and one step back in the traveling mode; then in the middle inner cylinder can fully absorb the heat, and also absorb middle heat of the drum, while extend the drying time, dry materials arein the best state now.

At last materials move to the middle of other end and fall into the outer, Within the outer cylinder rectangular loop way moving in the outer drum, the material which reach to the drying effect in the discharge of hot air action fast marching drum, the wet material which has not reach the effect of drying are not due to rapid travels because of the heavy weight. Within the rectangle shovelling plate sufficiently dried, thereby to complete the drying process.

1. Automatic and intelligent control system ensures the drying out of the straw/grain stalks/pea vine/potato vine/biomass fuel/lighten material/hay moisture uniformity and stability.

2. Remove stone and iron automaticly, ensures that the straw/grain stalks/pea vine/potato vine/biomass fuel/lighten material/hay of impurities do not enter the process after the drying of materials.

3. Equipment investment required is 1/6 of imported products cost.

4.The self-cylinder insulation thermal efficiency can reach above 70% (traditional monocular dryer thermal efficiency is only 35%), to improve the thermal efficiency of more than 50%.

5. Use the rear transmission, transmission more stable and reliable; revolutionized wheel rotation often slip phenomenon affecting production.

6. Reduce than monocular dryer covers an area of about 50%, construction investment is about 50% lower power consumption reduced by 60%.

7. A variety of circumferential feed composition distribution, effective regulation of drying time.Drying effect is good..

8. Easily control the final moisture indicators based on user requirements.

9. Adopts frequency motor speed to control material flow, according to user needs easily control the desired final moisture indicators.

10. The outlet temperature is low, dust removal equipment for a long time, continuous production of the next process.

11.The no pollution rotary drying kiln for biomass drying solution supported by new energy-saving stove, and is energy efficient, thermal control and simple operation, even the fuel consumption dropped about 60%.
