Annular cooler：

As the main equipment of pellet production process, annular cooler is a very common cooling equipment, which is widely used in the cooling of pellets. There are two main functions: blow cooling of high-temperature oxidized pellets discharged from rotary kiln after roasting to reduce its temperature to facilitate subsequent processing; As an important part of the heat balance of the whole process system, the heat in the high-temperature pellets is recovered and used for pre-heating treatment, thus reducing the fuel consumption of the whole system.

The annular cooler is mainly composed of driving device, rotating part, supporting roller, side retaining roller, pressure rail, frame, bellows, cover and so on. Transmission device for double transmission device, design to ensure that both sides of the equipment synchronous operation; The auxiliary drive device is provided to make the ring cooler run at low speed to protect the equipment in case of equipment failure; The rotating body part is the core of the whole equipment, by which the rotating operation of the material from the feed port to the discharge port and empty.
