摘　　要：由于低温粉碎的特点,避免了热敏性成分在粉碎过程中的损失,所以气流粉碎技术在生物材料微细化处理中得到广泛应用。论文主要介绍了气流粉碎技术对生物材料有效成分提取、超微粉体粒度及粉体特性和微观形貌特征的影响。认为物料特性和干燥预处理对于气流粉碎效果产生影响,应深入研究;可借鉴气流粉碎技术在矿冶、化工方面的应用,探讨气流粉碎过程的粉碎动力学、粉碎热力学、粉碎能耗规律以及粉碎过程中的微观形貌特征。It is widely used for the airflow grinding technology in the micronizing treatment of biomaterials because of the cryogenic pulverizing characteristic avoiding the heat-sensitive compositions loss during the grinding process.The effect of the airflow grinding technology on the active ingredients extraction,the particle size and its distribution,the micro-shape of biomaterials were mainly introduced.Considered that,it was necessary to investigate the influence of material characteristics and the drying pretreatment on the airflow grinding result.Taking examples from applications of the airflow grinding in the mining and metallurgy,the chemical engineering,it was worthy to analyze the grinding dynamics,the grinding thermodynamics,the grinding energy consumption law and the micro-shape feature during the airflow grinding process.
