?Shaking table instruction 一、?概况：? 摇床是用于选别细粒物料的重力选矿设备，它广泛应用于选别钨、锡、钽、铌和其它稀有金属和贵金属矿石，也可用于选别铁、锰矿石和煤。当处理钨、锡矿石时，摇床的有效回收粒度范围为2～0.04毫米。? 摇床的选矿过程是在具有来复条的倾斜床面上进行的（如图）。砂粒群从摇床面上角的给矿槽（砂槽）送入，同时由给水槽供给横向冲洗水。于是，矿粒在重力、横向水流冲力，床面作往复不对称运动所产生的惯性力和摩擦力的作用下，按比重和粒度分层，并沿床面作纵向运动和沿倾斜床面作横向运动。因此，比重及粒度不同的矿粒沿着各自的运动方向逐渐由A边向B边呈扇形流下，分别从精矿端和尾矿侧的不同区排出，最后被分成精矿、中矿和尾矿。由下图可看出床面矿流的运动方向。 ?一Description The table is a gravity separation equipment to choose fine materials, it is widely used in selection of tungsten, tin, niobium and other rare metals and precious metal ore, it can also be used for classifying iron, manganese ore and coal. When dealing with tungsten, tin ore, the table’s effective recycling scope is 2 ~ 0.04 mm. . Dressing table is in an inclined bed on the strip surface. Sand group is given from the table surface angle of the feeder, At the same time to sink by lateral flushing water supply, So, mineral particles are under the action of gravity, lateral impulsive force, inertial force and friction bed reciprocating asymmetric motion layered according to the proportion. And along the bed surface do longitudinal motion and transverse motion .therefore, Different density and size of particles along their respective direction of motion flow gradually from A side to B side . 牋 牋牋牋牋牋牋牋?rom A si???????????摇床工作示意图? 根据选别的矿石粒度不同，摇床可分矿砂（2～0.2毫米）摇床和矿泥（0.2～0.037毫米）摇床。两者的区别仅是床面上来复条的型式和选用的冲程、冲次不同，基本结构是相同的，所以，同一结构的摇床，只要更换不同型式的床面，就可以从矿砂摇床变为矿泥摇床。(?(According to the different selected ore size, shaking table can be divided into sand table (2 ~ 0.2 mm) and mud table (0.2 ~ 0.037 mm). The difference is only on selection of the stroke, the basic structure is the same, so, ,as long as replace different types of bed surface, can make the sand table become mud table 二、摇床的构造：主要由床面、传动机构（床头）和调坡机构等组成(。Two, the table structure: mainly consist of the bed,drive mechanism (bed) composition and gradient adjustment mechanism.) ? 床面形状有梯形和菱形两种。床面一般为木制。木制床面上铺有一层漆灰或橡皮（或采用聚氯脂耐磨橡胶作为耐磨层）。有的选矿厂采用水泥床面，以节省木材。在水泥床面上可涂上生漆，选矿效果也很好。还有使用聚氯乙烯塑
