Introduction of rotary dryer
Rotary dryer machine is divided into many types, for example, limestone dryer, roller dryer, rotary drum dryer and spray dryer.
Rotary drum dryer is strong adaptability to materials and can be used to dry all kinds of materials. This equipment is applied to cement plant for drying limestone, clay, coal powder and mixed materials and also used in metallurgy, mining, electricity, chemical industry and other sectors.
Rotary drum dryer is the most commonly used drying equipment in cement plant. It has many advantages such as sample and reliable operation, excellent dust prevention, good sealing effect and convenient maintenance.
Features of rotary dryer
1. High drying strength, wide applicability, available for many kinds of materials.
2. Short drying time, high processing quantity and high heating efficiency.
3. Simple structure, stable performance, easy to operate and maintain.
4. The rotary dryer can control the temperature of the barrel.
5. Small abrasion wear during movement, long working lifetime.
Working principle of rotary dryer
Rotary dryer is made up of the cylinder, lifting plate, transmission, supporting devices and others.
The wet materials are transported into the material hopper by the belt conveyor and bucket elevator and get into the feeding terminal through feeding pipe with the aid of feeder of the material hopper. The pitch of the feeding pipe should be higher than material pitch.
Since the dryer is put slantly, along with the revolving of cylinder, the materials move to the lower terminal due to the gravity. When the wet materials move forward, it receives the heat from the heat carrier directly or indirectly. Heat turns water into steam letting into the air, and aimed dry material is achieved.
