Product Introduction

    ( Flotation machine ) Abbreviation for flotation concentrator refers to the mechanical equipment that completes the flotation process. In the flotation machine, the ore slurry treated with the added agent is stirred and aerated to selectively fix some of the ore particles on the air bubbles; it floats to the surface of the ore slurry and is scraped out to form a foam product, and the remaining part remains in the ore slurry. In order to achieve the purpose of separating minerals. There are many structural forms of flotation machines. Currently, mechanical stirring flotation machines are commonly used.

    

     Machinery Factory Stirring Flotation Machine

    The aeration and stirring of the slurry of the mechanical stirring flotation machine are achieved by a mechanical stirrer, which belongs to an external air self-priming flotation machine. The inflatable agitator has the pumping characteristics similar to a pump, and it is self-priming and self-priming. Pulp. Commonly used for the selection of non-ferrous metals such as copper, zinc, lead, nickel, gold, etc. It can also be used for rough selection and selection of ferrous metals and non-metals.

     The mechanical stirring flotation machine (commonly known as type A) is characterized by:

    First, 18 to 20 guide vanes are installed on the cover plate.

    Second, the impeller, the cover plate, the vertical shaft, the intake pipe, the bearing, and the pulley are assembled into an integral part.

    Thirdly, a circle of upright fins is installed around the trough to prevent vortex flow from the pulp.

    Working principle of stirring flotation machine in Machinery Factory

    When the flotation machine is working, the impeller is driven by the motor triangle belt drive to generate a centrifugal effect to create a negative pressure. On the one hand, sufficient air is mixed with the pulp, on the one hand, the pulp is mixed with the medicine, and the foam is refined to make the mineral sticky. Above the combined foam, it floats to the surface of the pulp to form a mineralized foam. Adjust the height of the shutter and control the liquid level so that useful foam is scraped out by the scraper.

    After the coal slime and the agent are fully mixed, they are fed into the bottom of the first chamber of the flotation machine. After the impeller rotates, a negative pressure is formed in the wheel cavity, so that the pulp under the tank and in the tank are entered by the lower and upper suction ports of the impeller. The mixing zone also allows air to enter the mixing zone along the air guiding sleeve, where the slurry, air and medicament are mixed.

    Under the action of the centrifugal force of the impeller, the mixed slurry enters the mineralization area, the air forms bubbles and is crushed, and fully contacts the coal particles to form mineralized bubbles, which are evenly distributed in the tank under the action of the stator and the turbulence plate Section, and move up into the separation zone, enriched to form a foam layer, and discharged by the scraping mechanism to form clean coal foam.

    Flotation machine performance advantages

     High sorting accuracy

    It has strong adaptability to coal quality, high separation accuracy and high yield, especially its advantages for difficult coal preparation. The ash content of clean coal can be reduced by 1-2% compared with conventional mechanical stirring flotation machines.

     High output and low cost

    The processing capacity is large, and the processing capacity per unit volume is 2-3 times that of the conventional flotation machine. Low operating cost, compared with the conventional mechanical stirring flotation machine, it can save power 1 / 3-1 / 2.

     High degree of automation and easy maintenance

    There are no moving parts in the flotation cell, which is easy to maintain and repair. Small footprint, saving infrastructure investment. At the same throughput, the footprint is only 40-60% of the mechanical stirring type. Simple operation and high degree of automation.
