Coal Sludge Three Cylinder Rotary Dryer Introduction ofThree Cylinder Dryer This seriesof three cylinder rotary dryer is widely used in the cement, mining, buildingmaterials, chemical, and other industries for drying limestone, coal, slag, iron ore. Three cylinder dryeris composed of rotary body, liftingblade, driving device, supporting device and sealing ring. In order to controlthe temperature of the dryer, we set the heating coil in the out and inmaterial device. Three cylinder sand dryercan show the temperature changes of the dryer`s materialaccess through the thermometer. In order to better control the body temperature(usually 350-380 degrees), it provides a basis. AdvantagesofThree Cylinder Dryer 1. Three drumdryer is made of 16mm steel plate whose service life is 3 to 4 times longerthan common steel plate. 2. Selfinsulation efficiency of cylinder is as high as above 80%, which greatlyimproves thermal efficiency to 45%. (thermal efficiency of traditionalmonocular dryer is just 35%) 3. Fuel ofthree drum rotary dryer can be coal, oil, gas, etc. It can dry block, granularand powder materials with the particle size of 20 to 40mm. Technical ParametersofThree
