Secador de tambor rotatorio de tres pasos
The three-pass rotary drum dryer is an improved energy-saving product based on the single-cylinder rotary dryer.
This equipment is modified inside the single-cylinder dryer to increase the pre-drying of the wet material before entering the machine and extend the wet material the drying time in the machine, coupled with sealing, heat preservation and reasonable supporting measures, makes the production capacity of the dryer greatly improved compared with the original single-cylinder dryer, with advanced technology, reasonable operating parameters, and simple and feasible operation.
Capacidad: 8-100 t/h
Rotation speed(r/min): 4-10
Solicitud:
Drying of iron powder, mineral powder and other mixed materials, dry-mixed mortar and yellow sand for the construction industry, and raw materials for the chemical and foundry industries.
Structure of three-pass rotary drum dryer
The three-cylinder dryer is to change the single-cylinder body of the single-cylinder dryer into three stacked cylinders to shorten the overall size of the dryer body. When the machine is working, the material and the hot air flow enter the inner to outer cylinder in turn. After the z-shaped reciprocating flow of the machine body, the heat energy is used to dry the material before being discharged.
The cylinder part of the dryer is composed of three coaxially horizontally placed inner, middle and outer cylinders so that the section of the cylinder can be fully utilized. The overall length of the barrel shape is about 30-35% of the equivalent single barrel. To greatly reduce the floor space and the building area of the plant.
The supporting device of the machine is to support the roller belt and the supporting roller on the outer cylinder, and the supporting roller is directly driven by the motor. Through the friction between the supporting wheel and the tyre belt, the cylinder body is rotated. The overall structure of the machine is compact, reasonable and simple. To facilitate the maintenance and replacement of worn parts, it is designed as an axial split type in the middle, and the connection is fixed with bolts.
