石棉选矿乃是同时使用一系列特殊方法的一个例子。由于硬度和形状的差异,破碎产品中的石棉处于已松散或不松散的纤维状,而脉石则处于块状,在分选破碎产物的后续作业中,这种差别以及石棉和脉石在容重方面的差异,用于分级和吸棉。甚至可以利用摩擦和弹性的差异进行溜棉板选矿。石棉按等级进行的分级,取决于纤维长度及完整程度,以及被脉石颗粒和粉尘污染程度。由未变形纤维构成的长棉价值远远高于短纤维和严重松散的石棉。石棉选矿的主要任务不仅在于最大限度的回收石棉,而且在于得到每个等级的未变形纤维,等级棉之
Asbestos beneficiation is an example of using a series of special methods together. Due to the difference in hardness and shape, the asbestos in the crushed product is in the form of loose or loose fibers, while the gangue is in a lump form. In the follow-up operation of sorting the crushed products, the difference and the difference between asbestos and gangue in bulk density The differences are used for grading and suctioning cotton. You can even use the difference between friction and elasticity to carry a cotton wool dressing. The classification of asbestos by grade depends on the length and completeness of the fibers, as well as the degree of contamination by gangue particles and dust. The value of long-staple cotton made of undeformed fibers is much higher than that of staple fibers and severely loose asbestos. The main task of asbestos dressing is not only to maximize the recovery of asbestos, but also to get each level of undeformed fibers, grade cotton
