硅灰石、滑石等非金属矿气流超细粉碎及分级设备与工艺技术开发项目被列为国家重点企业技术开发计划第43项,国家建材局科技发展司和中国非金属矿工业总公司负责组织实施。该项目开发内容为通过对引进的联邦德国和日本设备的消化吸收,分别研制出国产化样机,并为系列化设计创造技术条件。以研制的样机为主机,分别在梨树硅灰石矿业公司和咸阳非金属矿研究所建立超细硅灰石粉示范生产
Wollastonite, talc and other non-metallic mineral flow ultrafine crushing and grading equipment and technology development project was listed as the key national enterprise technology development plan No. 43, National Building Materials Bureau of Science and Technology Development Division and China Non-metallic Mining Industry Corporation is responsible for organizing Implementation. The project was developed through the introduction of the Federal Republic of Germany and Japan, the digestion and absorption of equipment, respectively, to develop a prototype of the domestic and create a series of technical conditions for the design. Mainly to develop the prototype, were in Lisu Wollastonite Mining Company and Xianyang Institute of non-metallic minerals to establish ultra-fine wollastonite demonstration production
