Drum cooler / Rotary cooler

Drum cooler introduction:

Drum cooler is also called rotary cooler. A drum cooler is a kind of heat exchange device. It uses air as a medium to pass through high-temperature materials to cool the materials. The rotary cooler is a new type of drum cooler developed by our company staff with many years of experience in compound fertilizer production. Used in compound fertilizer production, cooling temperature, and particle size of fertilizer, used in a dryer, can greatly increase the cooling speed, reduce labor intensity, and increase output. In the compound fertilizer production line, it can further remove part of the water and reduce the size of the compound fertilizer. temperature.

Drum cooler structure:

1. Bracket part: The rotating part of the whole body is supported by the bracket, which bears greater force. Therefore, the Drum cooler bracket part is made of the medium carbon steel plate and channel steel welding and has passed strict quality control and special process requirements, which has reached the purpose of this machine.
2. Tug: In addition to the bracket, the more important thing is the supporting wheel fixed on the shelf. Considering that it will cause greater friction with the body roller, our factory specially selects high-quality anti-corrosion and wear-resistant materials, which greatly improves For the life of the rotary cooler, the supporting wheel frame also adopts the integrated casting technology. In addition, hoisting hooks are provided at the four corners of the supporting roller frame to facilitate loading, unloading, and transportation.
3. Transmission part: the transmission part of the whole Drum cooler is excellent and important. Transmission frames are made of channel steel welding and passed strict quality requirements. The main motor and reducer installed on the transmission frame are made of national standard products with reliable quality. The motor drives the belt pulley, the triangle belt, and the reducer to drive the spindle to make the bodywork. The reducer is in the working part of the spindle, and the nylon-logger coupling is used to interlock and transfer the drive.
4. Big gear ring: fixed on the machine body, toothed with the transmission pinion gear, opposite to drive the machine body to work, it uses high-tech wear-resistant materials so that the machine has a longer service life.
5. Rolling belt: fixed on both sides of the machine body to support the whole machine body.
6. Body part: The important part of the whole rotary cooler is the body part, which is welded by a medium carbon steel plate, the built-in lifting plate is made of wear-resistant materials, the distribution and angle are reasonable, and it has passed strict quality control and specific process requirements. , So that the material is raised to form a curtain to achieve the purpose of heat dissipation and dispersion of water powder. In order to achieve the purpose of this machine.

Working principle of Drum cooler:

The working principle of this series of Drum cooler is: the belt and pulley are driven by the main motor, transmitted to the driving shaft through the reducer, and the split gear installed on the driving shaft is meshed with the large ring gear fixed on the body, facing each other. jobs. The material is added from the feeding end, through the inside of the cylinder. The induced draft fan (used in conjunction with the machine) accelerates the airflow inside the cylinder, and the lifting plate installed on the inner wall of the whole body constantly turns the material up, so as to achieve the purpose of uniform cooling. The cooled material flows out from the discharge port. With the continuous rotation of the motor, the material continuously enters to achieve mass production.
