Technical Parameters of laboratory FX Model Mechanical Agitated Continuous Flotation Machine

一、用途

Ⅰ.Use

FX型械搅拌式连续浮选机适于实验室用浮游方法进行矿物选别。此浮选机是以二槽一组数台组连接起来做连续浮选机，槽数是偶数，自两槽到十槽不等，根据用户要求可为左式亦可右式浮选机。

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、结构说明

II. Structure

FX型浮选机属叶轮式机械浮选机，由以下主要部分组成：槽体部，以钢板焊接制造。其中利用叶轮搅拌及括板装置。

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、为了调正槽内矿浆液面及被刮出泡沫层的厚度，利用两槽壁板制成中间槽，其中安装矿浆液面调节器，在槽内罩盖上面安装孔板，用来防止矿浆的混乱运动对泡沫区的影响，同时也可以防止脉石被机械带到精矿中去。

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.

在槽体部置有衬板，防止磨损槽底，衬板可以更换，槽底外部置有排矿口，清洗时放水之用。

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.

矿浆流经壁板上的溢流口进入中间槽和尾槽，中间槽的下部与槽壁下部罩盖的导管进入下一个槽中，这样可以继续流经浮选机的槽数全部，从给矿槽流入，由尾槽的排矿口排出，槽体下部的前后置有进矿口，便于改变工艺流程。

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、叶轮系统，是安装在浮选机槽中心位置上，叶片向上成径向排列的盘状叶轮，固定在叶轮轴的下端绕竖轴管，管上端位于浆石和泡沫层之上，下端支承在罩盖上，当叶轮旋转时，沿竖管可吸入大量空气，在罩盖下面固定着防护盘，防护盘与叶轮之间隙大小与吸入空气量有关，其****间隙不超过3㎜，间隙过大时，更换磨损的防护盘，或适当调整之。

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.

竖管上的孔用来循环矿浆，并使矿浆与空气搅拌在一起，叶轮轴上部装在轴承壳内的滚动轴中旋转，轴承壳装在横梁上，轴的顶端固定着皮带轮，通过三角带接通电动机转动。调正三角带的紧张度由螺母来实现。

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、刮泡装置，泡沫利用回转刮板沿浮选机括出，刮板装在槽体的排矿口外，刮板轴一端装有皮带轮，动力通过蜗轮减速机及三角带传动而旋转。

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.
