Description

Technical Field

[0001] The present invention relates to the technical field of particle production, and in particular to a particle cooler and a particle processing method. Background Art

[0002] The working principle of the particle cooler is to reduce the temperature of the material through heat exchange. Specifically, it consists of a rotating cylinder with a lifting plate installed inside. The material exchanges heat in the drum through direct or indirect contact with the air, which can quickly absorb the heat in the material to achieve the purpose of cooling. Due to the rotation of the drum, the material is constantly turned in the drum, which allows every part of the material to be evenly exposed to the air, thereby ensuring the cooling efficiency and effect. However, when the amount of particles to be cooled is large, it is necessary to set the drum to a sufficient length to increase the cooling speed and cooling efficiency.
