Laboratory flotation cell

**- liters laboratory flotation machine is applied in ore dressing by the method of laboratory floating. It is concatenation floatation machine with several sets of machines. And the number of chutes is even from 1 to *0. It is left-type or right-type according to user’s demand.

Structure and features

Laboratory flotation machine with *9 liters is impeller mechanical flotation machine. It is composed by the following main parts:

(1). Tank

The tank 1 is welded with steel plate, using the impeller to stir, simultaneously inflating the air into pulp.

          In order to adjust the thickness of slurry surface in tank and foam layer scraped, the intermediate tank *5 is made up of two slot panels, in which is the pulp surface regulator 5 installed, orifice *7 is installed on the tank cover *4, which is used to prevent the chaotic movement of pulp affects on the bubble zone, the gangue is entrained mechanically to the concentrate.

Basin liner 6 is equipped in the tank to prevent the tank bottom worn, basin liner can be replaced. Discharging port 8 is placed outside the tank bottom, which is used to storage water when cleaning.

The pulp flows into the intermediate tank *5 and the end tank 3 from the overflow port on the panel, the catheters of the intermediate tank bottom and the cover *4 on the groove wall bottom are put into the next tank, which will flow continuously through all the tanks of flotation machine. The pulp is fed from the feed chute 3, is discharged from the discharging port 8 of the tailing 1, the feed port *6 is equipped in front and at the back of tank bottom, which is easy to change the technological process.

(2)Impeller system  

Impeller system is installed in the center of the flotation tank, the vertical arrangement coiled impeller 9 which leaves are up is fixed at the bottom of the impeller shaft *0 and around the vertical shaft tube *2. The tube top is located over the pulp stone and foam layer, the tube bottom is bearing the cover *4. When the impeller rotates, the quantities of air can be absorbed along the vertical tube *2. The protective plate 4 is fixed under the cover *4, the gap between the protective plate and impeller is related to the aeration rate, its maximum gap is less than 3mm, if the gap is too large, it is necessary to replace the protective plate or be adjusted appropriately.

The hole of vertical tube *2 is used to cycle pulp, and make the pulp and air mix well. The upper of the impeller shaft rotates in the rolling shaft *1 installed in the bearing shell, the bearing shell is installed on the beam 7. The pulley fixed at the top of the shaft makes the motor *8 rotating through the triangle belt, of which the tension can be adjusted by the nut *9.

(3). Shaving foam device

Foam is scraped using the rotary scraper along the flotation machine, scraper *0 is installed out of the discharging port. The pulley is installed at the end of the scraper shaft, which rotates through the driving of the worm reducer *1 and V-belt.
