The drying system of the rotary drum dryer is mainly composed of the following parts:
1. Rotary drum dryer main unit: This is the core part of the system, a slightly inclined and rotating cylinder, in which the material is dried.
2. Heat source system: Provides heat energy for the dryer. Common heat sources include coal, oil, gas, steam, electricity, etc.
3. Feeding system: Including equipment such as belt conveyors or bucket elevators, used to feed wet materials into the dryer.
4. Discharging system: Usually a belt conveyor or a screw conveyor is used to discharge the dried material from the dryer.
5. Dust removal systems: Such as cyclone dust collectors, bag dust collectors, etc., are used to capture and treat dust generated during the drying process.
6. Control system: Used to control the operation of the dryer, including the adjustment of parameters such as temperature, humidity, and wind speed.
Working principle of rotary drum dryer
1. Wet material entry: wet material enters the feed end of the rotary drum dryer through the feed system.
2. Heat source heating: the heat source system provides heat energy for the dryer to increase the internal temperature of the dryer.
3. Material drying: the wet material moves forward in the drum as the drum rotates, and at the same time, under the action of the internal heat source, the moisture in the material is evaporated to achieve drying.
4. Material forward: the rotation of the drum and the internal lifting plate make the material constantly lifted and sprinkled in the drum, and the material is fully in contact with the hot air flow to improve the drying efficiency and move the material forward.
5. Finished product discharge: the dried material is discharged from the discharge end, and the exhaust gas treated by the dust removal system is discharged into the atmosphere.
Product features of rotary drum dryer
1. Large processing capacity: the rotary drum dryer can handle a large amount of materials to meet the needs of large-scale production.
2. Easy operation: the equipment is easy to operate and easy to maintain.
3. Good drying effect: the material is in direct contact with the hot air, and the drying effect is uniform.
4. Strong adaptability: It can adapt to the drying needs of different materials, such as chemical, pharmaceutical, mining, and other industries.
