Flotation machine metal flotation beneficiation equipment manufacturer of professional full set of equipment supply

XJK XJK flotation machine flotation machine: XJK type (also known as A-type, XJ type) flotation machine, also known as Mine mechanical flotation machine, it belongs to a band of radiation air impeller self-priming machinery stirring flotation machine, widely used in copper, lead, zinc, nickel, molybdenum, gold and other non-ferrous metals, ferrous metals and non-metallic minerals roughing, selection and anti-flotation operations. XJK flotation machine structure and working principle: XJK flotation machine every two slots constitute a unit, with a first groove into the slurry pipe to suck the pulp, becomes known as aspiration and the second grooves of gravity or DC slot. Between the first groove and the second groove is provided in the middle room, the pulp is below pick a side. Impeller mounted on the lower end of the spindle. With the upper end of the spindle pulley, motor rotated. Air sucked by the intake pipe, each flotation cell slurry level adjustment by a shutter, mounted above the impeller cycle, the pore size can be adjusted by the lever. Work motor driven by a motor pulley and the spindle pulley spindle rotation, the impeller rotates along with the spindle, so between the cover and the impeller, a partial vacuum zone, the air sucked through the air tube from the straw. While pulp is sucked through the grout pipe, the latter two are mixed by centrifugal force generated by the rotation of the wheel by Xuan guide vanes being left to cover the edges of the slot. Strong stirring impeller pulp dispersed into the air bubbles and uniformly distributed in the pulp, when suspended mining and bubbles colliding contact buoyant mineral particles to adhere to the bubbles and mineralized zone to the surface layer of foam bubbles form and then scraped off by a blade as a concentrate, not attached to the bubble mineral particles as tailings into the next slot. Role XJK flotation machine: (1) the cover plates similar to the pump chamber causes a negative pressure zone, so that the pulp gravity, self-absorption and air circulation slurry tank movement. (2) by the rotation of the impeller of the air sucked into the bubble of granular and uniformly dispersed in the pulp, the impeller agitation and mineral particles and air bubbles suspended and full-contact. (3) result in the suspension of mineral particles. (4) Pharmacy fully dissolved and dispersed. The cover is a cast iron or rubber lined hollow disc, the above has opened a 18-20 hole pulp cycle. 18-20 with the bottom edge radius was 600 angle, obliquely arranged guide vane, which is inclined in the same direction with the rotational direction of the impeller. The role of cover are: (1) an impeller pump, to produce inflation effect, that is, when pulp was thrown impeller, a negative pressure in the suction cover. (2) guide vanes to throw the pulp from the diversion, reducing eddy currents that reduce water loss, play some steady flow effect. (3) adjusting the amount of slurry into the impeller, increasing the pulp inside the loop. (4) to ensure that the parking is not accused ore buried impeller, thereby preventing the motor when driving through the cut for easy maintenance and equipment to ensure that the impeller cover with concentric gap accurate spindle and the air tube and other equipment into one, with cheap parts hanging out of the slot as outside maintenance. To prevent pulp swirl in the bottom four weeks equipped with upright steady flow plate. By rotating the hand wheel and increase or decrease the weir gate 20 meters tailings liquid level adjustment. Weir located at the tailings sand sink to the bottom of the hole to make coarse and large density of mineral particles inhaled directly into the slot. In order to adjust the amount of slurry discharged through the sand hole with sand hole gate. Practical and theoretical studies have proven that improve aeration rate can greatly enhance the production capacity of the flotation machine, improve flotation.
