LTP型旁動隔膜跳汰機
 LTP Rectangle Compartment Side Way Action Type  Jig

旁動隔膜跳汰機，基本由Denver型跳汰機改制而成。其床層比較穩定，選別效果較好，隔膜與傳動裝置在跳汰機定一側，維修方便，但其占地面積和設備重量都比相同篩面規格的其他跳汰機大，動力消耗出略高，多用粗選及精選作業，適宜的分選粒度為12 -0.1mm，廣泛用于選別、金、銀、鎢、錫、鉛、鋅、錳、鐵等重金屬礦。

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型下動圓錐隔膜跳汰機
 LTA Below Pulsating Jig

下動圓錐隔膜跳汰機的隔膜位于跳汰室槽體圓錐部分和可動錐之間，故動力消耗少，重產物排出暢通。缺點是床層松散較差，選寬級別礦石時，粗粒級的回收較差。

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.

俗稱米哈諾布爾型，一般用于 6mm以下礦石的粗選作業，廣泛用于選別、金、銀、鎢、錫、鉛、鋅、錳、鐵等重金屬礦。

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型矩形跳汰機為下動式雙室跳汰機。由電動機帶動偏心軸承上的皮帶輪轉動，偏心軸總承經調節機構調節后產生不同心運動，從而帶動連桿做往復運動，連桿的另一端固定在搖框的轉動軸上，搖框中心有一個與機架相連接的支點，從而使搖框以支點為中心被動做上下往復運動。下動錐固定在搖框上也被動做上下往復運動，從而擠壓箱體內的水流產生波動，波動的水流穿過篩網沖擊篩面上的床石和礦物產生拋物運動，礦物在進礦口喂入，礦物在下落過程中因比重不同下落速度也不相同，從而自然分層。比重輕的礦物經床層進入下錐體，經下錐體精礦排出口排出，從而完成跳汰選礦過程。

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型矩形跳汰機有占地面積小，篩上水流分布均勻，處理量大等優點。

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

廣泛用于鎢、錫、沙金、鐵、錳、鈦、銻、鉛、鉭、鈮等重金屬。

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、操作對選礦的影響
 III. Effects of Operation on Beneficiation

跳汰選礦中，合理的操作是獲得良好分選效果的重要保證。影響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、沖程和沖次

1.  Stroke and Jig Frequency

沖程和沖次決定水流速度和加速度，影響床層的松散和水流對礦粒的作用，對于不同性質的礦料根據不同的選別要求，采用不同的沖程、沖次。

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.

大沖程和小沖次適用于處理粗粒礦石。

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

小沖程和沖次的選擇不是絕對的，與很多因素有關，因此選用沖程、沖次有幾種供參考：

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，需要大沖程;

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

處理量大，床層厚，需要大沖程；

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

篩下補加水小，需要大沖程

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

沖程系數小，需要大沖程；

Large strokes are needed in case of small stroke coefficient;

處理寬度級別物料時，增大沖程，減小沖次。

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

2、篩下補加水：

2. Undersized Supplementary Water

篩下補加水是減弱下降水流對礦物的吸入作用，提高精礦質量，增加上升水流，增強床層的松散度，有利于礦層按比重分層。補加水量隨給礦負荷、物料粒度、比重、厚度或床層松散度的不同而相對變化，一般物料負荷大，粒度粗，比重大，物料厚度，床層過緊，采用補加水量大，反之。補加水量小。選用寬級別物料時，必須采用小補加水量。

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、床層厚度和人工床層：

3. Bed Thickness and Artificial Bed

床層的作用是以控制它的厚度來調節精礦的質量和數量，床層越厚，礦粒越難透過，分選時間長，可以提高精礦質量，當入選物料比重差較大，或提高回收率時床層宜薄些，否則床層宜厚些。

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.

人工床層的床石比重按入選礦石的比重來定，一般與精礦比重相接近較合適。比重大不宜被上升水流沖散。反之不能再成層。床石粒度大，精礦品位低，回收率高。反之，精礦品位高，回收率低。一般床石粒度為精礦粒度的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、給礦濃度：

4. Feed Concentration

它決定跳汰過程中入選物料在水平流動速度的因素之一。濃度小，流速大，物料得不到充分跳汰，導致回收率下降。

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、處理量：

5. Handling capacity

處理量過大，導致礦物流失，過小精礦品位降低，入選礦物的粒度越細，可選性越好，水平流動越強，重礦粒度下降速度越快，處理能力越大，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.

（處理粒度的大小不能超出跳汰機規定的處理范圍）

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

LTC型側動外隔膜跳汰機
 LTC Side Way Action  Type Jig

側動隔膜跳汰機有側動外隔膜和側動內隔膜之分，外隔膜跳汰機又有梯形和矩形之分，梯形跳汰機是一種新型側動隔膜跳汰機，截面為梯形，沿礦流方向由窄變寬，礦漿流速漸減緩，有利于細粒重礦物的回收；全機由八個跳汰室組成，分成兩列，每列四室，各室的沖程、沖可單獨調節，組成不同的跳汰制度；結構制度為可拆式，便于運輸與搬遷；結構簡單，維修方便，運轉可靠。廣泛用于選別、金、銀、鎢、錫、鉛、鋅、錳、鐵等重金屬礦，給礦粒度范圍為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型粗顆粒跳汰機
 AM-30 Coarse Side Way Action Type Jig

AM-30型粗顆粒跳汰機和一般雙列側動矩形跳汰機相仿，專門用于處理粗粒礦石，入選礦石****粒度為 30mm，沖程為50 - 0mm；后者入選礦石****粒度可達50 - 70mm，沖程為100 - 0mm.目前這種跳汰機正在推廣使用中，廣泛用于選別、金、銀、鎢、錫、鉛、鋅、錳、鐵等重金屬礦。

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.
