在气射流磨机中磨矿,与其他磨矿法相比较有许多长处,因而是现代有发展前景的方法,为了采选工业技术更加进步,值得推广应用。属于此法优越性之点为,它具有高的生产率,可使选矿转变为干选,因破碎介质乃矿石本身,因而节省钢球消耗。有关铬矿石在气射流磨机中磨矿的试验是在全苏石棉科学研究设计院试验厂的工业装置上,在该院支持和技 Grinding in a gas jet mill has many advantages compared with other grinding methods and is therefore a promising method in the modern world. It is worth popularizing and applying it in order to make progress in the selection and selection of industrial technologies. Belong to the advantages of this method is that it has high productivity, can make dressing into dry election, because the crushing medium is the ore itself, thus saving the ball consumption. The test of chrome ore grinding in a gas jet mill is carried out on an industrial plant at the pilot plant of the Asbestos Scientific Research and Design Institute,
