(IV) Surrounding drum type high-voltage electric sorting machine A US Capco high-voltage electric sorting machine US Capco Company is a famous company specializing in the production of various high-voltage electric sorting machines. The drum type electric sorter is manufactured by the company. There are a large number of multi-drum, medium-sized single drum and experimental research series, which are characterized by high processing quality and different electrode structure from other drums. Figure 7 is a schematic diagram of its electrode structure. Figure 8 is a simplified diagram of a large-scale industrial production type Kapuco electric sorter with a throughput of 200 tons/hour. Featured mainly for iron ore, beach placer and the like. The Wabush iron ore processing plant in Canada processes 1,000 tons per hour. The Melmberget plant in Sweden produces 1 million tons of ultra-pure iron concentrate annually, all of which are based on the US Capco. Large electric sorter.
The advantage of this type of equipment is that it has a large amount of processing, high efficiency, and fine processing. The outstanding shortcoming is still the large amount of medium ore. The amount of minerals before the improvement is 40-50%. After changing to two Capco electrodes, it has dropped to below 40%. In addition, the highest voltage is still too low. Some refractory tantalum and niobium ore, and other beach placer selection is still incompatible. According to the author's experiments, the sorting voltage of these minerals exceeds 40 kV, often around 50 kV. [next]
B Soviet three-barrel high-voltage electric sorter In the world, the Soviet Union has conducted in-depth research and selection of electric drums. There are also many drum-type electric sorters developed.
a Three-drum type electric sorter This is developed by the Soviet Institute of Mines (ИΓД). Because there are three drums, the conductor, medium mine and tailings are more flexible and convenient. It is characterized by different electrode structure, completely using multiple corona poles, and without static electrodes, the corona pole is made of electric resistance wire or thin steel sheet with a thickness of 0.1 mm, the diameter of the drum is 300 mm to 350 mm, and the drum is long. 2 meters, the maximum voltage is 50 kV, the maximum current is 50 mAh, the processing capacity is relatively large, 1.5 to 2 tons per hour, which is much higher than the electric separator in China. Figure 9 shows the Su ΓД AH type three-drum high-voltage electric separator.
b Soviet HИД - Type 1 This electrostatic separator for sorting Soviet concentrate containing crude diamonds developed an electrostatic separator, FIG. 10 is a schematic view of the machine.
It is significantly different from ordinary point of the drum cartridge, different arrangements of one form of the drum, and second electrode structures has a special place. Using a corona electrode 2, there is no fixed electrode, and a second root immediately below the corona electrode has a tube mounted rotatably bakelite, to facilitate conductor aspirated. Such electric separator drum having a diameter of 200 mm, length 750 mm, the processing amount per hour of 1 t / m, which is mainly used for sorting the rough diamond concentrate.
Plate Punching CNC Machine
To furnish the varying desires of our customers, we are immersed in offering a world class consignment of CNC Plates Hydraulic Punching Machine. Features: Customized Reliable Fine finish Tough construction Durable .
â– Hydraulic station adopts dual-pump and single motor. Punching speed is faster than other company`s, so it is more efficient and improve the workshop ability.
â– It adopts sleeve-type coupling for all pipelines, which avoid leakage.
CNC feeding worktable can be divided into fixed part and movable part. The fixed part is set on the ground which is linked with main unit. To the fixed part, alongside the front-back direction of main unit is called Axis Y, and then the fixed part is called Axis Y rack. The movable part is installed on the Axis Y rack through the guide bush which is rolling in straight line, under the driven by the servo motor and ball screw shaft, the movable part is running though the Axis Y to realize precise positioning. To the movable part, alongside the left-right direction of main engine is called Axis X, and then the movable part is called Axis X rack. Axis X rack is closed to the head of the main engine, on both sides which is installed a supporting plate with universal transmission ball to support the work piece. At the back of the Axis X rack, two rolling guide bushes are installed with a sliding plate on the direction of Axis X. Under the driven by the servo motor and ball screw shaft, the sliding plate can running though the Axis X to realize precise positioning.
