How better choice grading equipment? In the process of crushing Shenyang Mining grader, ore particle size of from large to small not occur simultaneously, but gradually completed. In every stage of crushed grader, there is always some desirable fine particle generation out. In the grinding process, in order to separate the qualified fines promptly to prevent excessive crushing, improve mill productivity, the need to complete the grading equipment. Eligible particles from the classification overflow (sieve sieve under the product) feeding elected not work, coarse grinding and then grinding it returns. The current classification used in the concentrator equipment: spiral classifier, hydrocyclone and a fine sieve. 1) spiral classifier. This classifier is based on mineral particles of different sizes in an aqueous medium settling velocity difference to classification. Because of its simple structure, stable, easy to operate, widely used in the concentrator. Spiral classifier spiral surface height position and overflow in the tank at high weir type, sinking and low weir. Weir for the separation of high grain size greater than 0.15mm overflow, it is used for the first stage of grinding, and the sinking of less than 0.15mm grain size suitable for the separation of products, mostly in the second paragraph of the composition and grinding mill Closed. 2) hydrocyclone. Hydrocyclone is the use of centrifugal force to accelerate the settlement of mineral particles grading equipment, it requires pressure to mine, so power consumption of large, but small footprint, low price, large capacity, high-grade efficiency can be obtained very fine overflow stream product, used for the second stage of closed-circuit grinding grading equipment. 3) a fine sieve. Since the spiral classifier and hydrocyclone is classified according to the mineral particles of different sedimentation rate in an aqueous medium, it is easy to produce useful minerals enriched in the sand in the anti-causing valuable minerals over crushed. The fine screen is exactly as the geometry of grade ore particles with almost no impact on the density and high efficiency rating, so in recent years, a fine sieve for grading equipment in the grinding cycle and more attention. I can recommend the right equipment and models to the user based on the user's actual production situation and conditions, we will own professionalism and years of experience to you to make reasonable, cost-effective professional advice for your reference use flotation mechanical structure and characteristics of the flotation machine features: Flotation machine Structure: The machine is mainly composed of a stirring mechanism, tank, squeegee mechanism, the stator, the rotor ore tank level adjustment mechanism. 1, the impeller 1 by the stirring mechanism, a stator 2, a sleeve 3, bearing 4, tapered roller bearings 5, air pipe 6, sub large pulley 7, the small pulley 8, the motor 9 composition. Impeller radiation situation was arranged by the straight blade composition, coupled with what the upper cover plates. There on the cover open for inhalation endless loop hole at the bottom of the pulp used. The stator impeller covered and secured to the sleeve by a garden cover and vanes components. With axial and radial impeller clearance was 10 mm. Six outer stator cover long waist-shaped hole for center feed use, the inner circulation holes (φ35 mm) for the upper tank pulp cycle purposes. Because the impeller middle partition plate is inclined with the horizontal tilt angle, every space impeller rotates in a circle, the middle plate and the stator cover and lower cover and cover and leaf blade formed, each instant is changing Shenyang fine sieve machines, pulp impeller diameter from the central flow along the radial and axial has the speed difference, so the three-phase slurry bubble mixture alternately by rolling and extended role, which for pulp and bubble mineralization and favorable, thereby increasing the flotation rate. Pulp between the stator cover two laps inside and outside the loop hole of participating in the loop. 2, tank: tank cross section of inverted trapezoidal cross-section, and a secondary enrichment mineralization favor. Communication between the chambers, slurry flows into the impeller chamber to the next through the controlled gate and a central cavity into the bins. Center feeding under suction smaller than expected resistance, and can effectively prevent the string material for pulp flotation, flotation machine is the traditional way of feeding. 3, in case mine action: through the gate opened and closed in different parts of the election can be selected once or twice-election process. So that the flotation process has two advantages of flexible grader Beijing cone to accommodate a variety of pulp. Frequent changes in production status. 4, scraper mechanism: both sides of the upper portion of each tank float washing machine installed a set of rotating blades to scrape the foam concentrate. By the turbine gear, motors, pulleys, bearing, belt drive scraper shaft composition.
