LTP、LTA、LTC、AM型隔膜跳汰機(jī) Dissepiment jig

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

旁動隔膜跳汰機(jī)，基本由Denver型跳汰機(jī)改制而成。其床層比較穩(wěn)定，選別效果較好，隔膜與傳動裝置在跳汰機(jī)定一側(cè)，維修方便，但其占地面積和設(shè)備重量都比相同篩面規(guī)格的其他跳汰機(jī)大，動力消耗出略高，多用粗選及精選作業(yè)，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(jī) LTA Below Pulsating Jig   

下動圓錐隔膜跳汰機(jī)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(chǎn)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(yè)，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(jī)為下動式雙室跳汰機(jī)。由電動機(jī)帶動偏心軸承上的皮帶輪轉(zhuǎn)動，偏心軸總承經(jīng)調(diào)節(jié)機(jī)構(gòu)調(diào)節(jié)后產(chǎn)生不同心運(yùn)動，從而帶動連桿做往復(fù)運(yùn)動，連桿的另一端固定在搖框的轉(zhuǎn)動軸上，搖框中心有一個與機(jī)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(fù)運(yùn)動。下動錐固定在搖框上也被動做上下往復(fù)運(yùn)動，從而擠壓箱體內(nèi)的水流產(chǎn)生波動，波動的水流穿過篩網(wǎng)沖擊篩面上的床石和礦物產(chǎn)生拋物運(yùn)動，礦物在進(jìn)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(jīng)床層進(jìn)入下錐體，經(jīng)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(jī)有占地面積小，篩上水流分布均勻，處理量大等優(yōu)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(zhì)的礦料根據(jù)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(guān)，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(bǔ)加水小，需要大沖程

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

沖程系數(shù)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(bǔ)加水：

2. Undersized Supplementary Water

 篩下補(bǔ)加水是減弱下降水流對礦物的吸入作用，提高精礦質(zhì)量，增加上升水流，增強(qiáng)床層的松散度，有利于礦層按比重分層。補(bǔ)加水量隨給礦負(fù)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(fù)荷大，粒度粗，比重大，物料厚度，床層過緊，采用補(bǔ)加水量大，反之。補(bǔ)加水量小。選用寬級別物料時，必須采用小補(bǔ)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(diào)節(jié)精礦的質(zhì)量和數(shù)量，床層越厚，礦粒越難透過，分選時間長，可以提高精礦質(zhì)量，當(dāng)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(dǎo)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(dǎo)致礦物流失，過小精礦品位降低，入選礦物的粒度越細(xì)，可選性越好，水平流動越強(qiáng)，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(jī)規(guī)定的處理范圍）

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

LTC型側(cè)動隔膜跳汰機(jī) LTC Side Way Action Type Jig

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.
