Advantages of Silica sand three cylinder rotary drum drying dryer machine :

                                                                                          

1. Sand dryer is made of wear-resistant manganese plate, 3-4 times wear-resistant than ordinary steel plate. Raw material is with moisture within 15%, and moisture of dried material is lower 0.5-1%. Compared to traditional single cylinder drying machine, its thermal efficiency can be improved about 40% or more.

2. The outside cylinder temperature is lower than 60 degrees, and the waste gas temperature is lower than 120 degrees, and the service life of dust collector bag is more than twice of that of other collector. Coal consumption is one-third of the single cylinder dryer, save electricity 40%, with per ton consumption of standard coal lower than 9 kg.

 

Principle of Silica sand three cylinder rotary drum drying dryer machine 

                                                                                                  

Sand Rotary dryer is widely used for drying materials in industries like cement, mine, building materials, chemistry, food and fertilizer, etc. This rotary drying machine comes with thermocouples on the feeding and discharging device to control the temperature. Thermometers are also adopted so as to better control the working temperature (generally 350-380°) of the rotary drier.

Work Method  Of Rotary Drum Dryer, Industrial Mining Sand Dryer

Materials enter the inner side of the drum through the feeding device to realize current flow drying process, and 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.
