                  Three Drum Sand Dryer
                   
                  Description of Three Drum Sand Dryer:
                  Three drum dryer is used to dry humidity particle materials, such as yellow sand used by industry, variety of sand used in foundry industry, blast furnace slag which is used in cement industry of building materials, chemical, food, compound fertilizer, copra, etc. The particle size is small. According to requirements of the water in the products after dryer, the water content 1-0.5% or less can be achieved after process. Three Drum Dryer is widely used in mine, building materials, chemical, metallurgy, cast industries and so on. It can dry the material such as sand, slag, clay, fly ash, coal, iron powder, quartz sand, and ore and so on.
                   
                  Working Principle of Three Drum Sand Dryer:
                  1. The Three-drum Sand Dryer is composed of rotary cylinder, lifting blades, driving device, supporting device, sealing ring.
                  2. Material is fed at one end and discharged at the other end. In direct-type rotary dryers, hot gases move through the cylinder in direct contact with the material, either with or against the direction of its flow.
                  3. The cylinder is equipped with flights, which lift the material and shower it down through the hot gas stream.
                  Features of Three Drum Sand Dryer:
                  1. The internal adopts assembled structure which has improved the accuracy of the equipment and it is easy to transport and install.
                  2. According to the characteristics of different fertilizers, we have arranged the second granulation zone reasonably so as to improve the granulation effect.
                  3. Adopts assembled hoist board so as to exchange heat fully and lower the energy consumption.
                  4. Temperature induction monitor, uniform vibration and airproof setting, which improve performance and productivity efficiently
                  5. The assorted combustion furnace is a type of energy-efficient and has the characteristics of smaller area, easy regulation and equipped with temperature chamber.
