LTP、LTA、LTC、AM型隔膜跳汰机 Dissepiment jig

LTP型旁动隔膜跳汰机
LTP Rectangle Compartment Side Way Action Type Jig

旁动隔膜跳汰机，基本由Denver型跳汰机改制而成。其床层比较稳定，选别效果较好，隔膜与传动装置在跳汰机定一侧，维修方便，但其占地面积和设备重量都比相同筛面规格的其他跳汰机大，动力消耗出略高，多用粗选及精选作业，适宜的分选粒度为12 -0.1mm，广泛用于选别、金、银、钨、锡、铅、锌、锰、铁等重金属矿。

Compartment side way action type jigs are mostly transformed from Denver jigs. Their beds are stable and sorting effects are good. The dissepiment and transmission mechanism are at one side of the jig and is thus easy for maintenance. However, its occupying area and weight of equipment are larger than other jigs with the same sifter specification. Its power consumption is slightly higher. Such equipment is often used for fine screening and coarse screening. Its suitable separation size is 12-0.1mm. It is widely used to sort heavy metal ores such as gold ores, silver ores, tungsten ores, tin ores, lead ores, zinc ores, manganese ores, and iron ores.

LTA型下动圆锥隔膜跳汰机
LTA Below Pulsating Jig

下动圆锥隔膜跳汰机的隔膜位于跳汰室槽体圆锥部分和可动锥之间，故动力消耗少，重产物排出畅通。缺点是床层松散较差，选宽级别矿石时，粗粒级的回收较差。

The dissepiment of below pulsating jig lies between the jig tank conic part and movable cones. Therefore, the power consumption is low and heavy products are discharged smoothly. The disadvantage is the looseness of the bed is poor. When wide ores are selected, the recycle of the coarse grains are poor.

俗称米哈诺布尔型，一般用于 6mm以下矿石的粗选作业，广泛用于选别、金、银、钨、锡、铅、锌、锰、铁等重金属矿。

It is commonly called Mihanuobuer type. Usually it is used for the rough concentration of ores less than 6mm and is widely used in the sorting of heavy metal ores such as gold ores, silver ores, tungsten ores, tin ores, lead ores, zinc ores, manganese ores, and iron ores

二、工作原理
II. Working Principle

LTA-55/2型矩形跳汰机为下动式双室跳汰机。由电动机带动偏心轴承上的皮带轮转动，偏心轴总承经调节机构调节后产生不同心运动，从而带动连杆做往复运动，连杆的另一端固定在摇框的转动轴上，摇框中心有一个与机架相连接的支点，从而使摇框以支点为中心被动做上下往复运动。下动锥固定在摇框上也被动做上下往复运动，从而挤压箱体内的水流产生波动，波动的水流穿过筛网冲击筛面上的床石和矿物产生抛物运动，矿物在进矿口喂入，矿物在下落过程中因比重不同下落速度也不相同，从而自然分层。比重轻的矿物经床层进入下锥体，经下锥体精矿排出口排出，从而完成跳汰选矿过程。

LTA-55/2 rectangular jigs are upper movable double chambers jigs which drive the rotation of belt pulley on the eccentric bearings by the motor. The general bearing of eccentric bearings produces eccentric movement after the adjustment of regulating mechanism, so as to bring along alternating motion of connection rod. The other end of the connecting rod is fixed onto the rotating axes of vibrating frame. There is one supporting point in the center of the vibrating frame connected to the frame so as to get the vibrating frame to make up and down alternating movement around the supporting point. The lower movable cone fixed on the vibrating frame also makes up and down alternating movement so as to extrude the water flow in the tank to rise and fall. The rising and falling water flow passes through the screen mesh, impacts the bed stone on the sifter as well as generates projectile motion. The materials are fed at the inlet mouth. The minerals fall at different rates due to different specific gravity during the falling process so as to be naturally layered. The light minerals go into the lower cone through the bed and are discharged from the concentrate discharge mouth so as to finish jigging process.

LTA-55/2型矩形跳汰机有占地面积小，筛上水流分布均匀，处理量大等优点。

LTA-55/2 rectangular jigs enjoy advantages such as small occupying area, even distribution of water flow on the screen, and large handling capacity.

广泛用于钨、锡、沙金、铁、锰、钛、锑、铅、钽、铌等重金属。

This type of jigs are widely use in heavy metal such as tungsten, tin, alluvial gold, iron, manganese, titanium, antimony, lead, tantalum and niobium.

三、操作对选矿的影响
III. Effects of Operation on Beneficiation

跳汰选矿中，合理的操作是获得良好分选效果的重要保证。影响跳汰效果的主要因素有：

During jigging, reasonable operation is important guarantee to achieve good jig sorting effects. The main factors that affect jigging effects include:

1、冲程和冲次

1. Stroke and Jig Frequency

冲程和冲次决定水流速度和加速度，影响床层的松散和水流对矿粒的作用，对于不同性质的矿料根据不同的选别要求，采用不同的冲程、冲次。

Stroke and jig frequency decide water flow velocity and accelerated speed as well as influence the effects that looseness of bed and water flow have on ore grains. Different strokes and jig frequency are adopted for different natures of mineral aggregate according to different sorting requirements.

大冲程和小冲次适用于处理粗粒矿石。

Big stroke and small jig frequency apply to the treatment of coarse-grained ores.

小冲程和冲次的选择不是绝对的，与很多因素有关，因此选用冲程、冲次有几种供参考：

There is no absolute standard for the selection of small stroke and jig frequency. Many factors shall be taken into consideration. There are several reference standards for the selection of stroke and jig frequency.

粒度粗，比重大，需要大冲程;

Large strokes are needed in case of coarse grain and big specific gravity;

处理量大，床层厚，需要大冲程；

Large strokes are needed in case of large handling capacity and thick bed;

筛下补加水小，需要大冲程

Large strokes are needed in case of little undersized supplementary water;

冲程系数小，需要大冲程；

Large strokes are needed in case of small stroke coefficient;

处理宽度级别物料时，增大冲程，减小冲次。

Enlarge stroke and downsize jig frequency during the treatment of width level materials

2、筛下补加水：

2. Undersized Supplementary Water

筛下补加水是减弱下降水流对矿物的吸入作用，提高精矿质量，增加上升水流，增强床层的松散度，有利于矿层按比重分层。补加水量随給矿负荷、物料粒度、比重、厚度或床层松散度的不同而相对变化，一般物料负荷大，粒度粗，比重大，物料厚度，床层过紧，采用补加水量大，反之。补加水量小。选用宽级别物料时，必须采用小补加水量。

Undersized supplementary water weakens the suction effects of descending water flow on minerals, improves the quality of concentrate, increases ascending water flow, strengthens the looseness of bed, and is favorable for minerals to be layered according to specific gravity. The amount of supplementary water changes with the difference of feeding load, material particle size, specific gravity, thickness and looseness of bed. Generally, if materials have large load, coarse particle size, large specific gravity, large material thickness, and tight bed, large amount of supplementary water shall be adopted. Otherwise, small amount of supplementary water shall be adopted. During the selection of width level materials, small amount of supplementary water must be adopted.

3、床层厚度和人工床层：

3. Bed Thickness and Artificial Bed

床层的作用是以控制它的厚度来调节精矿的质量和数量，床层越厚，矿粒越难透过，分选时间长，可以提高精矿质量，当入选物料比重差较大，或提高回收率时床层宜薄些，否则床层宜厚些。

The function of bed is to, through the control of its thickness, adjust the quality and quantity of concentrate. The thicker the bed is, the more difficult it is for the ore gains to be permeated. The sorting time is long and the quality of concentrate can be improved. The bed is ideally thin when the specific gravity difference of selected materials is large or the recovery rate needs to be improved. Otherwise, the bed shall be thick.

人工床层的床石比重按入选矿石的比重来定，一般与精矿比重相接近较合适。比重大不宜被上升水流冲散。反之不能再成层。床石粒度大，精矿品位低，回收率高。反之，精矿品位高，回收率低。一般床石粒度为精矿粒度的3到5倍。

The specific gravity of the bed stone for the artificial bed depends on the specific gravity of the selected ores. Generally it is appropriate when it is close to the specific gravity of concentrate. If the specific gravity is large, it is not easily dispersed by the ascending water flow. Otherwise, layer can not be formed any longer. The particle size of bed stone is large; the grade of concentrate is low; and the recovery rate is high. Otherwise, the grade of concentrate is high and the recovery rate is low. In most cases, the particle size of bed stone is three to five times as large as the particle size of concentrate.

4、给矿浓度：

4. Feed Concentration

它决定跳汰过程中入选物料在水平流动速度的因素之一。浓度小，流速大，物料得不到充分跳汰，导致回收率下降。

It is one of the factors that determine the velocity of horizontal flow for selected materials during the jigging process. If the concentration is small, the flow rate is large, materials can not be fully jigged, and the recovery rate reduces.

5、处理量：

5. Handling capacity

处理量过大，导致矿物流失，过小精矿品位降低，入选矿物的粒度越细，可选性越好，水平流动越强，重矿粒度下降速度越快，处理能力越大，反之就越小。

Too large handling capacity leads to loss of minerals and grade decrease of too small concentrate. The finer the particle size of selected ores, the better their washability is, the stronger the horizontal flow is, the faster the descending speed of mineral particle size is, and the larger the handling capacity is. Otherwise, the smaller it is.

（处理粒度的大小不能超出跳汰机规定的处理范围）

(The particle sizes can not exceed the range specified by the jigs)

LTC型侧动外隔膜跳汰机
LTC Side Way Action Type Jig

侧动隔膜跳汰机有侧动外隔膜和侧动内隔膜之分，外隔膜跳汰机又有梯形和矩形之分，梯形跳汰机是一种新型侧动隔膜跳汰机，截面为梯形，沿矿流方向由窄变宽，矿浆流速渐减缓，有利于细粒重矿物的回收；全机由八个跳汰室组成，分成两列，每列四室，各室的冲程、冲可单独调节，组成不同的跳汰制度；结构制度为可拆式，便于运输与搬迁；结构简单，维修方便，运转可靠。广泛用于选别、金、银、钨、锡、铅、锌、锰、铁等重金属矿，给矿粒度范围为10 -0.2mm。

Side way action type diaphragm jigs are classified into side way action type external diaphragm jigs and side way action type internal diaphragm jigs. External diaphragm jigs are then divided into trapezoidal external diaphragm jigs and rectangular diaphragm jigs. Trapezoidal jigs are a kind of new side way action type diaphragm jig. Their cross sections are trapezoids which become wider along the direction of mineral flow: The flow velocity of slurry becomes gradually smaller which is favorable for the recycle of fine-grained ores. The whole machine is composed of eight jigging rooms in two rows, four rooms in each row. The stroke and jig frequency of each room can be adjusted independently to form different jigging system. The structure is of detachable, easy for transportation and moving. The structure is simple, easy for maintenance and reliable for operation. This type of equipment is widely used to sort heavy metal ores such as gold ores, silver ores, tungsten ores, tin ores, lead ores, zinc ores, manganese ores, and iron ores. The range of feed particle size is 10-0.2mm.

AM-30型粗颗粒跳汰机
AM-30 Coarse Side Way Action Type Jig

AM-30型粗颗粒跳汰机和一般双列侧动矩形跳汰机相仿，专门用于处理粗粒矿石，入选矿石****粒度为 30mm，冲程为50 - 0mm；后者入选矿石****粒度可达50 - 70mm，冲程为100 - 0mm.目前这种跳汰机正在推广使用中，广泛用于选别、金、银、钨、锡、铅、锌、锰、铁等重金属矿。

AM-30 coarse side way action type jigs are similar to double row side way action rectangular jigs. They are specially used to treat coarse-grained ores. The maximum particle size of selected ores is 30mm and the stroke is 50-0mm. For the double row side way action rectangular jigs, the maximum particle size of selected ores is 50-70mm and the stroke is 100-0mm. At present the use of such jigs (coarse slide way action type jigs) are being promoted. They are widely used to sort heavy metal ores such as gold ores, silver ores, tungsten ores, tin ores, lead ores, zinc ores, manganese ores, and iron ores.
