清华大学材料系粉体工程研究开发部根据国外雷蒙磨发展现状和国内现有技术条件,用自行开发的超细分级技术和设备,替代磨机原有的分析器,形成闭路循环,并由此取得对雷蒙磨技改的成功。此改造方案的特点是原设备改动小,不需要土建工程与之配套,投资小、工期短,在浙江湖州特种碳酸 Department of Materials Science and Engineering, Tsinghua University Powder Engineering Research and Development Department in accordance with the status of the development of foreign Raymond mill and domestic existing technical conditions, with their own development of ultra-fine grading technology and equipment, replace the mill original analyzer, the formation of closed-loop, This made Raymond grinding technical success. This transformation program is characterized by small changes in the original equipment, do not need civil engineering and supporting, small investment, short duration, in Zhejiang Huzhou special carbonate
