Flotation is mainly for solid-liquid or liquid-liquid separation. Large sum of micro bubbles produced by dissolving and releasing system adhere to solid or liquid particles with same density as waste water to make the whole float to the surface thus achieve the aim of solid-liquid or liquid-liquid separation.

The attapulgite, that is, the attapulgite, is an aqueous magnesium-rich aluminosilicate clay mineral having a chain layer structure. Due to the special physical and chemical properties and process properties of attapulgite clay, it has been widely used in petroleum, chemical, building materials, papermaking, medicine, agriculture and so on. The current domestic use of coatings, drilling mud, edible oil decolorization. Mining equipment for processing attapulgite: 1. jaw crusher The preliminary coarse crushing processing of the attapulgite is carried out in order to better carry out the later grinding treatment. The device has the advantages of simple structure, large processing capacity, uniform crushing, low investment, small volume, and convenient operation and installation. 2. high pressure grinding mill The high-pressure grinding mill is the core equipment of attapulgite processing. It adopts a three-dimensional structure to save space, and it can form a systematic grinding process. The fine powder of attapulgite after grinding is excellent in quality and impurities. Less, the screening rate is 99.99%, and the fineness can be adjusted between 30-425 mesh. 3. bucket elevator Bucket elevator has good stone conveying function, its own driving power is small, the lifting range is large, the operation is reliable, the service life is long, and there are few faults. 4. electromagnetic feeder The electromagnetic feeder is to send the stone uniformly and orderly to the main machine, which has many features such as simple structure, no lubrication, uniform feeding and continuous. Attapulgite processing process: The large attapulgite is initially crushed by the jaw crusher, and is transported from the bottom up to the silo by the bucket elevator, and then uniformly and continuously fed to the main machine under the action of the vibrating feeder (high pressure grinding mill) Powder machine) The inner powder is processed by the powder separator. The fine powder that does not meet the requirements is returned to the main machine for re-grinding. The fine powder that meets the requirements enters the finished silo or the powder tanker with the pipeline device. Uniform packaging can be.

Tray Type Centrifugal Gold Separation Machine LP600 also called gold panning machine in pioneers machinery factory as heavy medium separation appliance, is supported with hollow shaft and driven by power, with its major part being of cauldron disk. Slurry is transferred via slurry pump to the separation disk center where ore grains are acted by both gravity and inertial centrifuging force. During the course of movement by the ore grains upwards along the center of disk surface, when angle is greater than 45 degrees, the centrifugal component force in the direction of slope will gradually decrease while gravity component force will gradually increase. When it is up to a certain level, the two forces will reach balance, and near the point of balance easily develops a heavy mineral sediment layer. Tailings are discharged from edge at the upper disk, and concentrates after stop of feeding ( shut-down), are washed with water before being drained by hollow shaft. The major structure of the machine follows the technical data about gold washing from KNUDSEN, Australian mining company. The machine is primarily applied for washing and separating placer gold at a size of minus 4mm and is capable of recovering natural gold grains at sizes of over 15 um. In operation, inner hole of the center is blocked using plug with its drainage and collection at a regular basis. It can be operated intermittently or continuously, with the ore feeding and water adding simultaneously. The rotation direction is anti-clock( as indicated by arrow) at a speed of 70-110 r/pm. Ratio between solid and liquid for slurry is 1/4-2/3. The machine can be operated by power individually and multi-machines also can be operational in a combined or pedal manner ( without power supply ).

Working with contractors, engineers and plant operators, the staff at Pioneers factory constantly strives to improve the design based on the central transmission thickener principle and shallow subsidence theory in order to improve overall operation efficiency, installation and maintenance. Our pioneers company have developed a new high effect Inclined tube Clarifiers which has advantage of small size, less investment, low cost of operation, high thickening efficiency. Widely applied to in the sewage treatment of metals, on-metallic washing plant, building materials, chemical industry. Currently pioneers Inclined tube Clarifiers Widely used in tungsten, tin etc rare metals plant. Feeding slurry or other liquid into thickening zone from feeding zone. With suspended process in the thickening zone, big particle size will be discharged from the bottom outlet, because of settling velocity which overcomes water flow resistance. At the same time, small particle size minerals will flow up to the inclined tubes which are hexagonal thin-walled type. Accumulated to a certain amount of down under gravity to the settlement area, micro-fine will be overflowed. The process achieves the classification and thickening purpose.
