On the one hand, intelligent can reduce labor cost, remote monitor the operation situation at any time, and at maximun reduce failure rate. And on the other hand, the intelligent of coal slime dryer can immediately check the failures, and reduce wastes and accidents.
Three return the dryer actually is a kind of the three-cylinder dryer, and it is the upgrade product of three cylinders dryer. From the point of appearance, three return type dryer at one side is conical, and the other side is round, while three-cylinder dryer both the two ends are round. From the working principle to analyze, the cylinder is divided into internal cylinder, middle tube and outer cylinder, the working principle of three return dryer is same with the three-cylinder dryer. From the working efficiency of dryers, three return dryer is suitable for drying small amount of materials, and drying effect is better. While three-cylinder dryer is suitable for drying large amount of materials, and the drying effect is lower than three return dryer. From the covering area, three return dryer is smaller than three-cylinder dryer.
