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 .

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料床面。( The bed surface shape are trapezoid and diamond, The bed surface is generally made of wood. The wooden bed surface with a layer of lacquer ash or rubber, (Or the use of polyvinyl chloride grease resistant rubber as wear-resisting layer). Some concentrators using cement bed, in order to save wood. In the cement bed surface can be coated with lacquer, dressing effect is also very good. others use PVC plastic bed.

床面通常钉有木制的来复条或刻有沟槽。来复条的高度由给矿端向精矿端逐渐减小，以使分

层后的矿粒逐渐被横向水流冲下。( The bed surface is usually nailed a wooden rifles or carved with grooves. The height of rifles are decreasing from feed end to the concentrates, In order to make the stratified ore being laterally under water)

来复条的形状、尺寸和排列方法应适应给矿的要求。当处理粗砂时，希望造成对分选有利的涡流，因此采用高度较大的来复条，当处理细砂和矿泥时，希望矿泥流平稳，不产生强烈的旋涡，因此采用高度小的来复条或刻槽床面。以下为常用来复条的断面形状和排列方式。种类有：矩形（实用于矿砂摇床）、三角形（实用于矿泥摇床），梯形（实用于矿砂摇床）、锯齿形（实用于矿泥摇床），刻槽形（实用于矿泥摇床）。床面上端有给矿槽和给水槽。(The shape, size and arrangement on the strip method should meet the requirements for mine. When dealing with coarse sand, hope to contribute to the favorable vortex separation, so choose the high reflex, when dealing with fine sand and mud, hope mine mudflow smooth, does not produce strong vortex, so we choose the small rifle or caved bed surface. The following is often used to complex a section shape and arrangement.

Types are: rectangular (applicable to sand table), triangle (applicable to mud table), trapezoidal (applicable to sand table), zigzag (applicable to mud table), groove shape (applicable to mud table). The bed surface is provided with a feed chute and feed water tank.)

云锡式摇床是采用凸轮杠杆式传动机构（如下图），床面下设弹簧装置，弹簧座固定在地

基上。床面的后退运动依靠摇动机构，前进运动依靠弹簧装置，床面支承采用滑动支承。床面坡度采用楔形调坡机构调节。 (Yun xi type table is using cam lever drive mechanism (below), under the bed surface the is spring device, spring seat is fixed on the ground.

The bed surface back movement depends on the rocking mechanism , forward movement depends on the spring device, the bed surface is supported with sliding bearing. The bed surface slope is adjusted by wedge slope adjusting mechanism.

三、摇床的主要参数 (The main parameters of the table)

1.床面的形状和尺寸：床面形状有梯形和菱形两种。工业用摇床主要采用梯形床面。工业用床面尺寸（长×宽）一般为5400X1800毫米，长宽比为

2.5(The shape and size of bed surface: bed has trapezoid and diamond shapes. Industrial table mainly adopts the trapezoidal bed. Industrial bed size (length * width) is generally 5400X1800 mm, length and width ratio is 2.5)选别细泥时（－37微米占93％），其适宜的床面长宽比为2～2.5。(Choose fine mud (-37u m occupied 93%), the appropriate ratio is 2 ~ 2.5.)

2.冲程与冲次：冲程与冲次是根据被选矿物的粒度来选择的。粗粒矿物应选用大冲程低冲次；细粒矿物选用小冲程高冲次。冲程调节范围一般为8～25毫米，冲次调节范围为250～400次/分。 (Stroke and stroke : stroke and stroke frequency is selected according to the size of the selected mineral. Coarse grained minerals should choose large stroke low stroke frequency; of fine mineral particles with small stroke high stroke. Stroke adjustment range is generally 8 ~ 25 mm, stroke adjustment range is 250 to 400 beats per minute.)

3.设计摇床的传动机构时，冲程与冲次必须是可以调节的。电动机功率：摇床的电能消耗
