Centrifugal concentrators have the following advantages over planar chutes:
(1) Centrifugal concentrator is more effective in the treatment of fine slime, and the recovery rate of the grain size of 37~19 microns is as high as about 90%. Because the separation of the ore particles in the centrifugal concentrator is a combination of centrifugal force and lateral flow membrane, the enrichment ratio is higher than that of the planar gravity chute.
(2) Since the centrifugal concentrator utilizes the centrifugal force, the re-election process is enhanced and the sorting time is shortened. Therefore, its processing capacity is large, about 10 times that of the automatic chute.
(3) Small footprint and high degree of automation.
The main disadvantages are:
(1) Water consumption is larger than flat chute;
(2) The slope of the drum wall cannot be adjusted, and the production process is intermittent operation, and the continuous feeding cannot be performed.
Centrifugal concentrator in our country has become one of the main equipment of tungsten, tin sludge re-election in recent years and try to lean ore beneficiation of iron. The centrifugal concentrator is still being improved and improved continuously. While improving the equipment sorting index, it is focusing on the development of large-scale and continuous.
Chemical Pump is suitable for chemical, petroleum, metallurgical industry, electric power, paper making, foodstuff, pharmaceuticals and compound fabric industry etc., used for transporting all kinds of corrosive or similar to the medium of water pollution is not permitted. The over-flow parts of the pump are made of metal materials such as stainless steel or non-metallic materials such as fluorine plastic, which are resistant to acid and alkali corrosion. The shaft seal is generally mechanical seal to prevent leakage.
