The Qingdao Shina Air Classifier is designed to meet the classification requirements of flame retardant powders, with a D97 particle size of 40 micrometers. During operation, it exhibits the technical characteristics of fast classification speed and thorough particle separation. Compared with conventional screening and mechanical classification methods, it relies on air flow power to quickly sort coarse and fine particles, which can shorten the processing cycle for a single batch and adapt to the continuous production rhythm. At the same time, by relying on a stable classification force field and flow field control, it reduces particle agglomeration, entrainment, and sieve residue, allowing different particle size intervals to be clearly distinguished, reducing the probability of unqualified coarse particles being mixed into the finished product, and improving the batch consistency of the powder. 

In terms of process adaptability, this air-flow classification machine also supports simultaneous classification of multiple stages of particle size segments in series. It can flexibly divide multiple particle size intervals according to the formulation requirements of different application scenarios and collect them separately, meeting the particle size customization needs of various product lines such as high-end flame-retardant materials and general modified materials. The multi-stage classification capability not only reduces repetitive processing procedures, lowers energy consumption and material loss, but also enables enterprises to quickly switch classification parameters based on order specifications, enhancing the flexibility of production organization. 

Overall, the air classification machine, with its stable particle size control and flexible multi-stage classification configuration, aligns with the industry trend of fine processing of flame retardant powders. It helps manufacturing enterprises optimize powder quality, stabilize process parameters, and enhance overall production efficiency, providing reliable equipment support for the quality upgrade and capacity matching in the field of flame retardant materials.
