【摘要】 以贵定县粉石英矿为研究对象,利用干法加工工艺,用三种超细粉碎设备(瓷球磨,气流粉碎机,涡轮式粉碎机)对该矿石进行了超细粉碎。结果表明,三种设备都可使粉石英矿加工为-10μm以下的超细粉,且颗粒大小均匀,是一种S iO2含量高、白度高的优质矿物材料。更多还原

【Abstract】 This article describes three kinds of dry processing technologies,namely porcelain-balls-grinding,airflow-smashing and ultrafine-turbine-grinding to use for superfine grinding of Guiding konilite.The results indicate that all the three processing methods can produce superfine quartz powder that size is less than 10μm.The SEM pictures of the superfine powder quartz show the quartz has uniformity size,high brightness and high silicon dioxide content and can be used as mineral filler.更多还原
