由于电气石类型矿石中的锡石细粒浸染,必须选别高达50％—74微米的物料。这样细粒级中锡的回收显得特别重要。作为重选回收锡石精矿已经提供了一系列SKO型多层摇床(多达六层)。这些摇床对于选别-74+20微米产品有适宜的技术性能。单层面积为7.5米~2。这些摇床有斜的形状,而传动装置是双谐不平衡的。这些新型摇床比以前 Due to the digestion of cassiterite in tourmaline-type ores, materials up to 50% -74 microns must be selected. Such fine-grained tin recovery is particularly important. A series of SKO multi-layer shakers (up to six layers) have been provided for the re-election of recovery of Cassiterite concentrate. These shakers have the right technical performance for sorting -74 + 20 micron products. Single-layer area of ​​7.5 m ~ 2. The shakers have a slant shape, and the transmission is double-harmonic unbalanced. These new shaker than before
