Supply dryer, three-pass dryer

The three-pass dryer
is a new energy-saving dryer equipment from Jieheng Machinery Manufacturer. This machine is a high-efficiency combined dryer. It has a three-layer insulation effect and adopts a circulating insulation structure, which can effectively Prevent heat loss during the entire drying process, thereby effectively improving thermal efficiency and productivity. The three-pass dryer adopts a tong-type structure, which is mainly composed of an inner cylinder, a middle cylinder and an outer cylinder to form a self-insulating structure.

In addition, the drum is wrapped with insulation materials and stainless steel plates to seal every link, making the equipment more efficient, energy-saving and environmentally friendly. This equipment can be used to dry raw materials such as yellow sand, river sand, quartz sand, slag, clay, etc. It is widely used in building materials, chemical industry, casting and other industries, and can be adapted to various fuels such as coal, oil, and gas.

Working principle of three-pass dryer
The material is sent to the hopper by the conveying equipment, and then enters the feeding end through the feeding machine and feeding pipe. Pay attention to this place. Make the feeding pipe have a natural inclination, so that the materials can naturally flow into the barrel of the three-pass dryer. The cylinder has a certain slope, and then rotates at a constant speed. The material enters from the high end, and the heat carrier enters from the section, causing countercurrent contact. Of course, a common phenomenon is that the heat carrier will flow into the cylinder together with the material. With the rotation and gravity inertia, the material will naturally flow to the lower end. The wet material directly exchanges heat with the heat carrier in the cylinder to achieve the drying effect, and then is sent out by the conveyor equipment.
