39- 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 10. It is left-type or right-type according to user's demand. Structure and features: Laboratory flotation machine with 39 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 15 is made up of two slot panels, in which is the pulp surface regulator 5 installed, orifice 17 is installed on the tank cover 14, 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 15 and the end tank 3 from the overflow port on the panel, the catheters of the intermediate tank bottom and the cover 14 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 16 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 10 and around the vertical shaft tube 12. The tube top is located over the pulp stone and foam layer, the tube bottom is bearing the cover 14. When the impeller rotates, the quantities of air can be absorbed along the vertical tube 12. The protective plate 4 is fixed under the cover 14, 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 12 is used to cycle pulp, and make the pulp and air mix well. The upper of the impeller shaft rotates in the rolling shaft 11 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 18 rotating through the triangle belt, of which the tension can be adjusted by the nut 19. (3). Shaving foam device Foam is scraped using the rotary scraper along the flotation machine, scraper 20 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 21 and V-belt.

The demostration meter is used to demostrate the working principle of AC and DC Ammeter, Voltmeter and Galvanometer with the help of interchangeable plastic Scales. Amagnetically damped spring controlled moving coil movement is housed in a plasic case with glass front and rear panel. A pair of 4 mm socket terminals is give on the right side to apply voltage and current. A special locking arrangement and a centrl / side zero adjustment control is given on the left side with the help of two knobs. The interchageable scales are boldy marked on both sides enabling the class to view from the front and the demostrator from the rear. Each scale is fitted through a slot on the right side of the case and has a plug connector which also serves to locate and align the scale positively in position.
