FX Model Mechanical Agitated Continuous Flotation Machine is applicable to separation of minerals with Float-free method in labs. It is a unit of several combinations of two cells with number of the cell being even, varying from two to ten cells. Left or right type flotation machine can be supplied as required by customer.

二、結(jié)構(gòu)說明

II. Structure

FX型浮選機(jī)屬葉輪式機(jī)械浮選機(jī)，由以下主要部分組成：槽體部，以鋼板焊接制造。其中利用葉輪攪拌及括板裝置。

FX flotation machine is a kind of impeller mechanical flotation machine which mainly consist of cell. It is made of welded steel plate and through impeller agitation and scraping device.

1、為了調(diào)正槽內(nèi)礦漿液面及被刮出泡沫層的厚度，利用兩槽壁板制成中間槽，其中安裝礦漿液面調(diào)節(jié)器，在槽內(nèi)罩蓋上面安裝孔板，用來防止礦漿的混亂運(yùn)動(dòng)對(duì)泡沫區(qū)的影響，同時(shí)也可以防止脈石被機(jī)械帶到精礦中去。

1. To adjust the level of slurry in the cell and the thickness of the scraped froth layer, use wall plates of the two cells to make intermediary cell; install slurry level regulator; and mount orifice plate onto the cover in the cell to avoid negative effects on the froth zone exerted by the chaotic motion of slurry, as well as to avoid the gangue from being taken into the concentrate by the machine.

在槽體部置有襯板，防止磨損槽底，襯板可以更換，槽底外部置有排礦口，清洗時(shí)放水之用。

Lining plates are installed at the cell so that the bottom of the cell will not be abraded. The lining plate can be replaced. On the outside of the cell bottom is a discharge mouth, which is used to discharge water during its cleaning.

礦漿流經(jīng)壁板上的溢流口進(jìn)入中間槽和尾槽，中間槽的下部與槽壁下部罩蓋的導(dǎo)管進(jìn)入下一個(gè)槽中，這樣可以繼續(xù)流經(jīng)浮選機(jī)的槽數(shù)全部，從給礦槽流入，由尾槽的排礦口排出，槽體下部的前后置有進(jìn)礦口，便于改變工藝流程。

The slurry flows through the overflow mouth of wall panel into the intermediary cell and tail cell. It flows to the lower part of the intermediary cell and the duct covered by the lower part of the cell wall and then to the next cell. In this way, it can continue to flow through all the cells of flotation machine. It flows from the feed cell and is discharged from the discharge mouth of the tail cell. The front and back of the lower part of the cell is installed feeding mouth, to make it easy to change the process flow.

2、葉輪系統(tǒng)，是安裝在浮選機(jī)槽中心位置上，葉片向上成徑向排列的盤狀葉輪，固定在葉輪軸的下端繞豎軸管，管上端位于漿石和泡沫層之上，下端支承在罩蓋上，當(dāng)葉輪旋轉(zhuǎn)時(shí)，沿豎管可吸入大量空氣，在罩蓋下面固定著防護(hù)盤，防護(hù)盤與葉輪之間隙大小與吸入空氣量有關(guān)，其****間隙不超過3㎜，間隙過大時(shí)，更換磨損的防護(hù)盤，或適當(dāng)調(diào)整之。

2. The impeller system is a disk impeller which is installed in the center of the cell in the flotation machine and whose blades are radially arranged. It is fixed onto the lower end of the impeller shaft and revolves around the vertical shaft pipe. The upper end of the pipe lies above the pulp stone and the froth layer while its lower end is supported on the cover. When the impeller rotates, a large amount of air can be sucked along the vertical pipe. Below the cover is fixed protective disk. The gap between the safety disk and the impeller depends on the amount of sucked air. It can not be larger than 3mm at most. When the gap is too large, replace the abraded protective disc and make appropriate adjustment.

豎管上的孔用來循環(huán)礦漿，并使礦漿與空氣攪拌在一起，葉輪軸上部裝在軸承殼內(nèi)的滾動(dòng)軸中旋轉(zhuǎn)，軸承殼裝在橫梁上，軸的頂端固定著皮帶輪，通過三角帶接通電動(dòng)機(jī)轉(zhuǎn)動(dòng)。調(diào)正三角帶的緊張度由螺母來實(shí)現(xiàn)。

The holes in the vertical pipe are used to circulate slurry as well as mix the slurry and air. The rolling shaft installed inside the bearing shell above the impeller shaft rotates. The bearing shell is installed on the crossbeam and belt pulley is fixed on the top of the shaft which rotates through the V-belt when the motor is turned on. The tension of the V-belt is adjusted through the nuts.

3、刮泡裝置，泡沫利用回轉(zhuǎn)刮板沿浮選機(jī)括出，刮板裝在槽體的排礦口外，刮板軸一端裝有皮帶輪，動(dòng)力通過蝸輪減速機(jī)及三角帶傳動(dòng)而旋轉(zhuǎn)。

3. Scraping device: The froth is scraped along the flotation machine through rotary scraper. The scraper is installed outside the discharge mouth of cell. At one end of the scraping shaft is installed belt pulley which rotates through the drive of worm reducer and V-belt.
