Flotation Machine

Flotation machine for sorting colored black metal, but also for non-metallic such as: coal fluorite, talc sorting. The flotation machine driven by the motor V-belt drive wheel rotates, centrifugal vacuum formed, on the one hand inhalation of sufficient air is mixed with the slurry, while stirring the pulp is mixed with drugs, while refinement of foam, mineral adhesive foam on top to make , float to the surface and then form slurry bubble mineralization. Ram height adjustment, control surface, so that bubble is a useful scraper scraped off.

Flotation machine refers to the mechanical equipment to complete the flotation process. In the flotation machine, the pulp is added after the pharmaceutical treatment, by stirring inflatable, make some mineral particles are selectively adhered to the top of the bubble; float to the pulp surface is scraped to form a foam product, the rest is retained in the pulp in order to achieve the purpose of separation of the mineral. Flotation machine structure of many, the most commonly used is the mechanical flotation machine.

Development Description Of Flotation Machine

1911 Montana built the first industrial flotation machine flotation plant processing -150 purpose sphalerite. 1912 flotation froth flotation technology in Australia and the United States promoted. 1910--1915 years Yes flotation technology invention and diffusion heyday.

Froth flotation process flotation machine industrial jobs has been widely used for sorting ore and coal particle size less than 0.3mm particle size of less than 0.5mm, and depleted, disseminated grain size becomes small, the degree of structural complexity as the ore grade increase and the increasing requirements for comprehensive utilization of resources, the tonnage of ore flotation process applications is growing.

Industrial flotation machine model number, depending on the needs of sorting different flotation. In addition to the flotation method for sorting metals, non-metallic minerals and energy minerals, is also widely used in industrial waste water purification plants, and especially the use of flotation separation of microscopic size particles and hydrogen separation using flotation machine equipment iron oxide precipitate flotation and other tests in the study, which has received a number of flotation mines the majority of applications.

Flotation Machine Working Principle

The ground ore, after grinding or milling when necessary, add water and stirred tank into a chemical pulp after the start of injection of the slurry was stirred tank, introducing air into the slurry to the formation of large bubbles, some of the water can not easily be moist, that is generally referred to as the hydrophobic mineral particles attached to bubbles, and the bubbles float along with the pulp to the surface, forming a layer of mineralized bubbles and others likely to be wet water, that is generally referred to as hydrophilic mineral particles not attached to the bubbles, and stay in the pulp, containing a specific mineral mineralized bubble discharge, so as to achieve the purpose of dressing.

Flotation Machine Basic Principle

Flotation machine driven by the motor V-belt drive wheel rotates, centrifugal vacuum formed, on the one hand inhalation of sufficient air is mixed with the slurry, while stirring the pulp is mixed with drugs, while refinement of foam, mineral adhesive foam on top to make, float to the surface and then form slurry bubble mineralization. Ram height adjustment, control surface, so that bubble is a useful scraper scraped off.

After thorough mixing slime and potions to the bottom groove of the first chamber flotation machine impeller rotation, a negative pressure in the wheel cavity, making the slurry tank bottom and slot, respectively, by the impeller breathe into the mouth and on mixed zone, but also makes the air along the guide sleeve into the mixing zone of gas, pulp, mixed air and agents here.

In the impeller centrifugal force, the pulp mixture into the mineralized zone, the formation of air bubbles and was crushed, and full access to coal particles, formation of mineralized bubbles and turbulence in the stator plate under the action of uniformly distributed in the tank section, and move up into the separation zone, enriched to form a foam layer is discharged from the bubble scraping mechanism, the formation of coal bubble.

Sorting swivel rotates slowly, when the sorting room into a floating field area, this time selected by the pulp material, respectively, to the distributor to 6 sorting point, weakly magnetic mineral particles being sucked in with the tooth plate and sorting ring is rotated. Non-magnetic mineral particles in the slurry flow under gravity through a gap tooth plate, into the lower portion of the tailings sorting ring groove. Go to the sorting room when the cleaning position in the mine, a small amount of washing water is fed into the entrained gangue, with the living body wash and slime tailings slot (slot machine is not set in the mine), so as to improve the quality of concentrate the goal of. When the sorting room to weak magnetic field position (concentrate rinse area), pressurized water is injected into the suction plate teeth weakly magnetic mineral particles into the concentrate tank. Then the sorting room to another area of the magnetic field of opposite polarity, sorting each revolution of the ring, wherein each separation chamber so repeated six times.

Flotation Machine Working Efficiency

Flotation machine driven by a motor triangular substituting transmission impeller rotates, centrifugal vacuum formed, on the one hand inhalation of sufficient air is mixed with the slurry, while stirring sand washing machine pulp mixed with the drug.

In the flotation process, mineral ups and downs almost mineral independent of density. Such as chalcopyrite and quartz, the former density of 4.2, which is 2.68, but the heavy mineral chalcopyrite is easy to float, quartz instead sink to the bottom. The study found that mineral water and its floatability disc feeder affinity for the size, all with large affinity for water, minerals easily wetted by water, difficult to attach to the bubbles floating difficult. The low affinity with water, mineral water can not easily be wetted easily float. Therefore we can say, based on mineral flotation is wettability of different beneficiation methods based. Usually easy to float mineral nature and difficult to float called mineral floatability. Flotation is the use of mineral floatability difference to sorting minerals. In modern flotation process, the application of flotation reagent is particularly important because after flotation reagent processing, you can change the floatability of minerals, so that confidential floating mineral flotation can be selectively attached to the bubble, so as to achieve beneficiation purpose .

If the flotation pulp contains more slimes, flotation would bring a range of adverse effects. The main impact of the following:

  • 1. Easily mixed with the foam products, the concentrate grade dropped.
  • 2. Easy to cover on the treated surface, the impact of coarse flotation.
  • 3. A large number of adsorption agent increase drug consumption.
  • 4. So sticky pulp, inflatable conditions deteriorate.
