New High Efficiency Rotary Dryer Mineral Processing Equipment Triple Pass Dryer Rotary Dryer
Triple pass dryer is a new type of rotary dryer, mainly used for drying granular material with certain humidity and particle size in the range of requirements, material in a non stick tube wall and the lifting plate is appropriate, material’s water content is in the range of 5-25%. The dryer heat flow is not higher than 800 ℃. If there are special requirements of high temperature drying, the entrance of the inner cylinder and lifting plate can be made of heat resistant steel plate. After drying, the final water content of the material, according to different industries and process requirements, can reach 1-0.5%.
Features and technology advantages
1.It can do heat preservation by itself, and its heat efficiency can be as high as 80%, Besides, it can save as much as 68% energy and its productivity is 100% higher.
2.Its length is 60% shorter than that of single cylinder dryer, which makes it easy to arrange.
3.Its alloy steel plate is heat and wear resistant, and its abrasive performance is 4 times of that of general steel plate. Besides, it has longer service life and is easy and convenient to maintain.
4.Its outer cylinder has a temperature lower than 60℃, and the discharge temperature is lower than 60℃.
5.The temperature of its discharge hole is low, which helps to prolong the service life of environmental protection equipment, and it can also work together with air tank pulse bag filter.
The wet material into the inner cylinder of the feeding end, is quickly pushed to the spiral lifting plate by the spiral guide plate. With the rotation of the cylinder, the spiral lifting plates set up in three cylinders make the materials lifted, at the same time, the materials continue to roll, scatter and do longitudinal motion. At the same time the hot gas flow from the heat source successively enters the inner drum, the middle drum and the outer drum and to meet the material for a strong heat exchange. The thermal conductivity of metal plate is faster than that of materials, steel plate and lifting plate of cylinder of the first heat, then the heat by conduction and radiation transmitted to the material, the material is heated, when the temperature rises to the evaporation temperature, water vapor is separated from the material, discharged with the dust into the atmosphere, so as to achieve the purpose of drying materials.
