Ore dressing machine

When the impeller of the aerated mechanical agitation flotation machine rotates, the pulp in the tank is sucked into the impeller blades from the bottom of the tank from all sides, and then enters the impeller blades through the holes around the distributor. After the pulp and air are fully mixed between the impeller blades, the pulp returns to the impeller area for recirculation and enters the lower tank for re-selection. It is suitable for roughing and selecting operations in large and medium-sized ore dressing plants, and can select non-ferrous metals, ferrous metals and non-metallic minerals. The particle size range of the selected materials is 0.3-0.01mm (-0.074mm particle content>50%).

SF type mechanical stirring flotation machine is a self-priming pulp and gas machine. It can be widely used in the selection of non-ferrous metals, ferrous metals, and non-metallic minerals, and is suitable for roughing and scavenging operations in large and medium-sized flotation plants. The impeller of the flotation machine has backward-inclined blades on both sides, which can realize the double circulation of pulp in the tank; the forward-inclined tank has small dead angle and fast foam movement speed.

XJK flotation machine is driven by an electric motor through a V-belt to drive the impeller to rotate, generating a centrifugal effect to form a negative pressure, on the one hand, to inhale sufficient air to mix with the slurry, on the other hand, to stir the slurry and mix with the drug, and at the same time to refine the foam, so that the minerals are adsorbed on the foam, float to the surface of the slurry and then form mineralized foam. Adjust the gate height to control the liquid level so that the useful foam is scraped out by the scraper. At present, it is widely used in the selection of non-ferrous and ferrous metal minerals in China, and can also be used for the selection of non-metallic minerals.

The impeller of the mixing barrel is driven by a V-belt of an electric motor and is mainly used for stirring before flotation. It is a necessary equipment for fully mixing the reagent and the ore pulp, increasing the reaction time of the reagent and strengthening the quality of the drug reaction. It is used for concentrations not exceeding 30%, and is suitable for stirring various metal ores and non-metallic minerals, suitable for mining, and can also be used for stirring in various chemical industries.

The mud separator is a simple equipment for classification, desludging and concentration. Its appearance is an inverted cone. A feed cylinder is set at the center of the liquid surface, and the bottom edge of the cylinder is submerged to a certain depth below the liquid surface. The slurry is fed into the center cylinder along the tangent direction and flows out from the bottom edge after being buffered. The outflowing slurry flows radially to the peripheral overflow weir. At present, it is mainly used to desludify the raw ore to improve the classification efficiency; it is also installed in front of the grinding equipment to concentrate and dehydrate the ore to increase the feed concentration of the grinding machine; it is also used to control the feed concentration and ore quantity in front of various ore slime separation equipment.

The hydraulic classification box is an iron pyramidal box with a wedge-shaped sand blocking bar on the top and a classification box bottom valve on the bottom. The settled sand is discharged from coarse to fine. It can be used for washing clay minerals; as an auxiliary operation, it can be used for pre-classification, inspection classification, and control classification of the grinding cycle, or for dehydration and desludging; as a preparatory operation, it can be used for classification before separation such as shaking tables.

Hydraulic classifier is a particle size classification equipment. It has the advantages of high efficiency, low energy consumption, and no noise. It is used with a mineral processing shaker and is an equipment system in the professional field of mineral classification. The suitable classification particle size is 2-0.074mm, and the feed concentration is 18%-25%. When the classification particle size is less than 0.074mm, the classification effect is also poor. The advantages of hydraulic classifier equipment are simple structure, no power, reliable operation, and it is widely used in tungsten-tin ore processing plants.

The spiral classifier is a kind of equipment that uses the principle that the solid particles have different specific gravities and different precipitation speeds in the liquid to perform mechanical classification. It is widely used in ore dressing plants to form a closed-loop circulation with the ball mill to divert ore sand, or to classify ore sand and fine mud in gravity ore dressing, to grade the ore pulp in the metal ore dressing process, and to remove mud and water in ore washing operations.
