The customized three cylinder dryer is scientifically reasonable, efficient and energy-saving. The material exchanges heat with the hot air flow in the inner cylinder through radiation, convection, and conduction, while in the outer cylinder, heat exchange is carried out through a combination of conduction and convection. The dryer has high thermal efficiency and significant energy-saving effect. After testing, the thermal efficiency greatly exceeds the level of traditional dryers by about 50%. After the equipment is put into operation, the coal saving effect is significant. This machine adopts the material and hot air flow co current drying process, which has a wide range of applications. It can adapt to the drying of various raw materials such as clay, coal, slag, iron powder, and is also suitable for the drying of various bulk materials in metallurgy, chemical industry and other departments. Compact structure. The whole machine is horizontally arranged and supported by idler wheels, eliminating the transmission of large and small gears and replacing it with idler wheel transmission, making equipment installation more convenient, operation simpler, operation more reliable, and operation rate higher.

The external surface area of a three cylinder dryer is reduced by more than 30% compared to a single cylinder rotary dryer, and the outer cylinder has a thermal insulation effect on the inner cylinder. The surface temperature of the outer cylinder is low, resulting in less heat loss. While being highly efficient and energy-saving, it greatly improves the working environment and conditions. Multiple types of lifting plates are designed, and the organic combination of angular lifting plates and cross shaped lifting plates enables more complete exchange between materials and hot flue gas, reducing the mechanism of "wind tunnels" inside the dryer cylinder. Adopting frequency conversion speed regulation, adjusting the cylinder speed, and adopting appropriate speed according to the inlet moisture and production requirements to ensure meeting the needs of the next process. Automatic temperature monitoring system makes operation more convenient.
