( 1 ) Dehydration and de-dosing operations, generally using traditional center and peripheral transmission concentrators. When the handling capacity is not large, the center transmission type should be preferred. The main advantage is that it can be manually or automatically lifted to prevent crushing accidents. When the processing capacity is large, the peripheral transmission type is adopted, and the material density is small, and the roller type can be preferentially considered. On the contrary, the rack type can be selected, and the rack type can also prevent slipping.
(2) gold cyanide plant (wet or smelter) and the precipitate was washed operations, generally multi-layer concentrator.
( 3 ) When the concentrator is installed indoors in a narrow and cold area, a high-efficiency thickener can be used. However, due to the use of flocculants and the impact on the next process, reliable test data must be used.
( 4 ) Concentrator feed size, generally less than 250μm . If the feedstock particle size cannot be reduced for any reason, it should be considered that the slurry is first treated by mechanical classification, centrifuge or cyclone, and the coarse particles are separated and then fed into the thickener.
( 5 ) The production capacity of the concentrator or the required sedimentation area shall be determined according to the material settlement test, or may be selected according to the production quota of similar enterprises. After determining the specifications of the concentrator, it should be checked according to the rising water flow, generally less than the free settling velocity of the particles of 5 μm .
(6) inclined plate box was concentrated, it is used for small jobs concentrated ore dressing plants, and wastewater treatment operations.
