three-return dryer
The three-return dryer is divided into 623, 625, 628, 6210 und 6220. The three-return dryer is a choice equipment for drying non-cohesive mnaterials such as river sand and sand. As long as the materials which can be dispersed naturally
after being loosened by hand, they can be dried by a three-return dryer.
The so-called three-return dryer is a high-efficiency dryer equipment with three-layer heat insulation effect and self-insulation structure. It is reasonably inlaid by three cylinders according to certain mathematical relationship,
which effectively prevents heat emission. Its heat value utilization rate can reach more than 90%, and it is an industrial dryer with high heat energy utilization rate at present. The main advantage is that the heat preservation
effect is better than that of the traditional single drum dryer. The dryer consists of inner drum, middle drum and outer drum to form a self-insulation circulating structure, which has higher working efficiency, more energy-saving
and environmental protection.
