Triple Pass Rotary Drum Dryer Overview
Triple Pass Rotary Drum Dryer Introduction
The triple pass rotary drum dryer is a new type of drying equipment developed by Zhengzhou Dongding Drying Equipment Co., Ltd. in order to reduce the occupied space of drying equipment and improve the efficiency. It can be used for drying wood chips, sawdust, bark, straw, coco peat, Fiber, palm silk, alfalfa hay, sugarcane bagasse, cassava residues, etc. And the final product can be applied in boiler combustion, gasification and power generation, animal feed. 
The equipment consists of three parts: the inner cylinder, the middle cylinder and the outer cylinder. System design Reasonable, well-produced, stable performance, advanced technology, high output, low energy consumption, small footprint and high degree of mechanization. After the improvement of applicability of our technical personnel, the effect is very good in the treatment of high-humidity materials.

Triple Pass Rotary Drum Dryer Working Principle

The material is 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 air, complete the drying process, the final product are discharged by the screw conveyor. 

Triple Pass Rotary Drum Dryer Advantages
1.Compared with the single-drum dryer, the length of the machine is shortened by 50%, reducing the building area and saving about 40% project investment.
2. The hot air stove can be equipped with boiling furnace, spray coal stove, hand-fired stove, biomass fuel hot air stove, also used for fuel, gas stove, can bake a block of less than 20mm, granular material, powder, slurry-like materials.
3.The equipment has large processing capacity, strong anti-overload capability, low energy consumption, and can directly reduce the drying cost;
4. The use of co-current, counter-current, mixed flow and other drying technology, greatly improving the thermal efficiency;
