Description

What is the Rotary dryer?

Rotary dryer is a common and widely used drying equipment, also known as rotary drying machine, or three-cylinder dryer. It completes the drying process through the structure of a rotating drum. Rotary dryers usually consist of a cylinder, heat source, driving device, exhaust device, and control system.

The heating methods of rotary dryers can vary according to different drying needs and process requirements. Common heating methods of rotary dryers: Biomass, natural gas, diesel, coal, etc.
The number of rotating cylinders of this machine can be customized according to customer needs, and a single cylinder or multiple cylinders can be connected in parallel to suit different application scenarios.

Rotary dryers are suitable for materials of various humidity and particle sizes. They are widely used in food processing, chemical industry, metallurgy, building materials, environmental protection, and other fields. They are used to dry various powders, lumps, and granular materials, such as slag, potassium feldspar, quartz sand, sawdust, river sand, coal Ash, medicine residue, grain, etc.

Working principle of Rotary dryer 

The working principle of the machine is to put the wet materials into the rotating drum. Through the rotation of the rotating drum and the action of the heating source, the materials are fully heated and dried during the drying process. Hot air or heat source conducts heat to the material through the wall of the rotating drum. The moisture on the surface of the material evaporates into water vapor under the action of heat, and then the moisture is discharged through the exhaust port. The finally dried material is discharged from the rotary dryer through the discharge port.

Features of Rotary dryer 

1. Efficient energy consumption: Through reasonable heat conduction and convection heat transfer mechanisms, thermal energy can be effectively converted into evaporation heat of materials, reducing energy waste and operating costs.
2. Continuous operation: The rotary dryers have the capability of continuous operation. Materials can be continuously fed, and dried materials can be continuously discharged to achieve a continuous drying process.
3. Advanced control system: It can accurately control parameters such as temperature, humidity, rotation speed, drying time, etc.
4. Short drying time: the drying cycle of materials is generally only 10-3000 seconds, suitable for heat-sensitive materials.
5. High thermal efficiency: Its general thermal efficiency is about 80-90%.
