Three cylinder drying machine|Sand dryer|3 drum dryer|Triple pass rotary dryer Quality Assurance Compact structure,small floor area,the length cut down 60% than single cylinder rotary dryer,be helpful to plant layout. Customized Scheme Fuel of three-drum rotary dryer can be coal,oil,gas,etc.It can dry block,granular and powder materials. High Yield Self insulation efficiency of cylinder is as high as above 80%, which greatly improves thermal efficiency to 45%. (thermal efficiency of traditional monocular dryer is just 35%). Product features It's without rack wheel transmission,but uses riding wheel drive, which is of smooth operation,high running rate,less maintenance,low cost,etc Working principle Materials enter the inner side of the drum through the feeding device to realize current flow drying process,then the materials enter the middle layer of the inner wall through the other end to realize counter current drying process.They are lifted in over and over in the middle layer which advance in two-steps forward and one-step back way.The three-drum dryers absorb heat from both inner drum and middle drum,which extend the drying time and realize the best drying condition.Finally,materials fall into the external layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way.The dried materials move quickly out of the drum under the hot air,while the wet ones remain because of their own weight.Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus finishing the whole drying process.
