Sand dryer is also known as the three layers of drum dryer, three return cylinder dryers, on the basis of the single-cylinder dryer, developed and manufactured, which is an industrial dryer on non-viscous, liquid material. At present three-cylinder dryer made by Jiutian company, with mature technology, through the drying of the sand, fly ash, coal, mineral materials, slag, and other material, the effect is very good.
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 a 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 fed libraries, without cooling.
The sand is conveyed to the silo by belt conveyor or bucket elevator, and transport to the feed end by the feeder of the silo. The inclination of the feeding pipeline should exceed the natural inclination of materials so that to facilitate sand flowing into the dryer smoothly. The rotating cylinder of the dryer is slightly inclined to the horizon. To feed the material from the higher end and the heat carrier enter from the lower end, such produce adverse contact between them .sometimes, they can be fed to the cylinder together. As the cylinder running, the sand carried to the lower side by gravity. In the process of moving forward, the wet raw material being roasted by the heat directly or indirectly to make the raw material to dry quickly, the final products discharge out by belt conveyor or screw conveyor. There is a shoveling plate installed in the dryer with the function of shoveling the materials up and down, to enlarge the contact area between airflow and materials and to enhance the efficiency and make the material running quickly. The heat carrier is hot air, the flue gas, etc. After the dryer process, It needs a cyclone dust collector to catch the items in the airflow. You should use a bag type or wet-type dust collector and afterward discharge the waste gas if you intend to further reduce the dust load of the exhaust.

The sand dryer ordered by Hunan customers applies Jiutian's newly developed drying technology. At the same time, it combines the characteristics of sand with special equipment to dry the sand to the customer's demand.
