Main Features of Rotary Drum Dryer:
1. High mechanization degree, large production capacity and continuous operation
2. Simple structure, smooth running and convenient operation
3. Less fault, low maintenance cost and low power consumption
4. Wide application range and good drying uniformity
5. High drying temperature, high drying intensity and low cost
Sand Dryer Drying Machine Product Advantages:
1. The sand dryer is made of alloy steel plate manufacturing,the wear-resisting 3-4 times of ordinary steel , the service life of the equipment is more than 10 years.
2. Material initial moisture content 15%, final moisture to ensure below 0.5-1%,which is the preferred products of the cement plant, GGBS and dry mortar production line.
3. The sand dryer thermal efficiency is as high as 80%, at the same time, the total power is low, 40% energy saving.
4. The fuel can be adapted to the coal, oil, gas,it can be dried under 20-40mm particles material, aggregate, powder material.
5. The sand dryer covers an area of about 40% lower than single drum dryer and civil investment reduced by about 50%.
6. No air leakage phenomenon, solved the sealing difficulties, modular units, installation is convenient.
7. The discharge temperature is < 50 ºC,which can be directly feed libraries, without cooling.
Rotary Drum Dryer Application
The rotary drum dryer is special designed for drying muddy and high humidity materials, like coal, lignite, wood chips, sawdust, rice husk, herbal medicine, forage grass, chicken manure, minerals, ore powder, bean dregs, fruit residues, etc. It is widely used in agricultural, building materials, chemical industry, and other industries.
The wet material is evenly distributed and dispersed in the rotary dryer after entering the dryer from one end under the turning of the lifting board uniformly distributed in the inner cylinder. The wet material fully contacts with the parallel flow (countercurrent) hot air, thus accelerating the heat transfer. In the drying process, under the action of inclined plate and hot air flow, the material moves to the star discharge valve of the other section of the dryer to discharge the finished product
