Three way rotary dryer

Brief description: Overview: The material is fed into the inner cylinder and undergoes a composite motion of rolling in the circumferential direction and axial movement through the lifting plate inside the drum, which fully heats and dries the wet sand. Then, it enters the middle cylinder through the guide plate for drying, and finally the dry sand enters the outer cylinder for cooling to between 50-60 ℃ before being discharged from the dryer; The three return drum dryer is made of outer, middle, and inner cylinders, with the inner cylinder being at high temperature and the middle cylinder being at high temperature,

The material is fed into the inner cylinder and undergoes a composite motion of rolling in the circumferential direction and axial movement through the lifting plate inside the drum, allowing the wet sand to be fully heated and dried. Then, it enters the middle cylinder through the guide plate for drying, and finally the dry sand enters the outer cylinder for cooling to between 50-60 ℃ before being discharged from the dryer; The three return drum dryer is made of outer, middle, and inner cylinders, with the inner cylinder being at high temperature, the middle cylinder being at high temperature, and the outer cylinder being at low temperature.

This equipment has high thermal utilization rate, small footprint, and can also achieve material cooling effect, with a thermal efficiency increase of about 40% compared to traditional single drum dryers. This equipment is widely used in industries such as dry mixed mortar, yellow sand, cement plant slag, clay, coal, building materials, chemical industry, and casting.
