Rotary Drying and Cooling Machine

Overview of rotary drying and cooling machine

The rotary drying and cooling machine is a kind of high-efficiency equipment integrating drying and cooling, which is widely used in chemical industry, fertilizer, mining industry, building materials and other industries.

The rotary drying and cooling machine realizes the continuous drying and cooling process of materials in the same body, which saves space and equipment investment and simplifies the process.

The rotary drying and cooling machine has the advantages of large processing capacity, strong adaptability, easy operation and maintenance, energy saving and environmental protection, etc. It is an indispensable and important equipment in the production of fertilizers.

The working process of rotary strand drying and cooling machine:

Drying stage:

Material input: the material enters the drying section from the inlet of the rotary strand drying and cooling machine. The drying section usually adopts the downstream or countercurrent heat transfer method, the heat is provided by the heating source (such as hot air furnace or burner), and the hot air is in direct contact with the material to evaporate the moisture in the material.

Drying process: the material in the drying section with the rotation of the equipment is constantly turned and lifted, the material in the role of gravity slowly moving forward, and at the same time with the full contact of the hot air, and gradually complete the drying process. By adjusting the temperature and time of the drying section, different drying requirements of materials can be realized.

Cooling stage:

Cooling process: after drying the material into the cooling section, the cooling section usually adopts the counter-current cooling method, that is, the cold air and hot material flow in the opposite direction. Cold air is introduced through the fan, and contact with high temperature materials, quickly take away the heat, so that the temperature of the material is reduced to a suitable level.

Cooling is completed: the cooled material is discharged from the equipment through the discharge port, and the whole process realizes the continuous drying and cooling of the material, which ensures the quality of the material and the production efficiency.

Overview of rotary drying and cooling machine

Feeding device: The material enters the equipment evenly through the feeding device to ensure the smooth progress of the drying and cooling process.

Drying section: the drying section is the core part of the equipment, built-in multiple coping or lifting device, used to continuously turn and lift the material, increase the contact area between the material and the hot air, improve the drying efficiency.

Cooling section: The cooling section is equipped with a cooling fan, which realizes the rapid cooling of the material by contacting the material with the counter-current cold air. The design of the cooling section ensures the uniformity and stability of the cooling effect.

Transmission system: the transmission system of the equipment consists of electric motor, reducer and transmission chain, which ensures the stable operation of the equipment. The transmission system is reasonably designed with smooth operation, low noise and low energy consumption.

Discharging device: The discharging device is located at the end of the rotary drying and cooling machine, designed as an adjustable structure, which can control the speed and quantity of the material discharged to meet the needs of different production processes.

Supporting structure: the supporting structure of the rotary drying and cooling machine is welded with high quality steel, which has a solid structure and can withstand the vibration and impact of the equipment in work, ensuring the stability and safety of the equipment.
