由中国颗粒制备与处理专业委员会和中国国际贸促会建材分会联合组成的考察团一行15人,于1997年5月5～10日参加了第22届美国芝加哥国际粉体工业展览会。各国共575家厂商和研究开发机构云集芝加哥,展示了最新研究成果和产品,内容涉及与粉体加工处理有关的冶金、化工、建材、矿业、轻工、食品、医药、机械、农业等领域。 1 粉碎分级设备 (1)大处理量超细粉碎设备的开发,均是与超细分级机组形成超细粉碎/分级系统。传统的雷蒙磨的改造在美国相当成功。ABB和PI公司的此类设备以石灰石的干式超细粉碎为例,比表面积10 000 cm~2/g的产量可达2 t/h以上。 (2)高性能的粉体加工设备离不开高性能材料的支持,材料工业的高技术产品对粉碎机易损件的设计提供了新的选择,使无污染粉碎设备成为可能,如刚玉衬板的腭式破碎机、全刚玉
A delegation consisting of 15 members from China National Committee for Particle Preparation and Processing and China Council for the Promotion of International Trade Building Materials Branch attended the 22nd International Powder Industry Exhibition in Chicago from May 5 to May 5, 1997. A total of 575 manufacturers and R & D institutions from all over the world gathered in Chicago to showcase the latest research results and products in areas such as metallurgy, chemicals, building materials, mining, light industry, food, medicine, machinery and agriculture related to powder processing. 1 crushing and grading equipment (1) large capacity ultrafine grinding equipment development, are ultra-fine grading unit formation of ultra-fine crushing / grading system. The traditional Raymond mill transformation in the United States quite successful. Examples of such equipment from ABB and PI are dry, ultrafine limestone, with a specific surface area of 10 000 cm 2 / g up to 2 t / h or more. (2) High-performance powder processing equipment can not do without the support of high-performance materials. The high-tech products in the material industry provide new choices for the design of the wearing parts of shredders, making it possible to use non-polluting shredding equipment such as corundum lining Plate palate crusher, all corundum
