Product Details of rotary drum cooler
Fertilizer after drying have high temperature,if you want to pack them you need to cool them first. Rotary drum cooler machine is used to cool fertilizer temperature and particle size in compound fertilizer production line and organic fertilizer production line. The rotary cooler machine is used together with the rotary drum dryer, which can greatly increase the cooling rate, reducing labor intensity, increasing capacity, and further remove the moisture and reduce the temperature of fertilizer. Besides, rotary drum cooling machine can also be used for cooling other powdery or granular material. Generally, the feed temperature is 60℃-80℃, and the discharge temperature is less than 40℃.
Rotary drum cooling machine are similar to rotary dryers. They are designed using a rotating cylinder called a drum. The material to be cooled is fed into one end of the drum and discharged at the other. To move the material through the drum, the cylinder is tilted down slightly at the discharge end. As the material is fed into the drum, internals in the drum lift and/or mix the material to improve the heat transfer between the material and either the air in the drum of the shell of the drum.
There are two basic types of rotating drum coolers, convective coolers. In the case of convective coolers, a stream of air moves through the material in the drum. Indirect drum coolers use water to cool the shell of the drum instead of streaming air through the drum.
features of rotary cooler machine
