Three Cylinder Rotary Sand Dryer
Three cylinder rotary sand dryers adopt the latest energy saving technology with embedded type structure. Inner cylinder, middle cylinder and outer cylinder form a self insulation structure. Thermal insulation material and stainless steel plate covered the drum, which effectively reduce heat loss and improve the thermal efficiency.

Advantages:
1. It adopt latest anti-wear technology with thicker materials,greatly improve the service life.
2, Low fuel consumption. Power consumption is lower 40% than traditional dryer.
3, The fuel can be coal, oil, natural gas etc, dry mass and granule and
powder material.
4, Unique design in constructure with patent right. No air leakage phenomenon,
solved the sealing difficulties.
5, It use roller wheel transmission instead of gear transmission to prolong the dryer
service life.
6, Discharge temperature ≤ 60 degrees , which can be directly go to storage silo,
no need for cooling.
7, Outer barrel temperature ≤60 degrees, exhaust smoke temperature < 120
degrees which enable dust removal bag prolonged service time more than 2 times.

Working principle of three cylinder rotary drum sand dryer:
1. The three cylinder rotary drum dryer in scientific and compact design. The material at internal cylinder make heat exchange with hot air flow in form of radiation, convection and conduction. The heat exchange at the outer cylinder in conduction and convection both. With this flow, the three cylinder rotary drum dryer has high thermal efficiency and remarkable energy-saving effect.
2. The material and hot air flow comply with drying process, which enable the dryer in wide range application on drying clay, coal, slag, iron powder and other raw materials in metallurgy, chemical industry and other departments. Three cylinder rotary drum dryer with compact structure in horizontal layout, and improved using supporting wheel instead of traditional gear drive to simply equipment installation and operation, high output efficiency with reliable performance.
3. The external surface area of the three cylinder rotary dryer is reduced by more than 30% than that of the single cylinder rotary dryer, and the outer cylinder kept thermal insulation on the inner cylinder, thus the outer cylinder surface temperature is low and less heat loss, this greatly improving the working environment and working conditions.
4. A variety design used on lifting plate to guarantee the material and heat air exchange completely and reduce the dryer cylinder inside the "wind tunnel" space.
5. Adopt frequency control system to realize adjust the cylinder speed according to the input moisture and capacity to ensure that meet the needs of the next process.
