Reselection method
Reselection method is to divide the mineral beneficiation composition according to the difference in relative density (specific gravity generally known) is. Mineral particles of different densities are subjected to hydrodynamic forces and various mechanical forces in the moving medium (water, air and heavy liquid), resulting in suitable loose delamination and separation conditions, so that different density of ore particles can be separated.
2. Flotation method
The flotation method is based on the difference in physical and chemical properties of the mineral surface, and is treated by a flotation agent to selectively attach the useful mineral to the bubble to achieve the purpose of sorting.
Non-ferrous metal ore beneficiation, such as copper, lead, zinc, sulfur, molybdenum and other miners to use flotation process; some ferrous metals, rare metals, and some non-metallic minerals, such as graphite ore, apatite, also with floating Choose the law.
3. Magnetic separation method
The magnetic separation method is based on the difference in mineral magnetic properties, and different minerals are subjected to different forces in the magnetic field of the magnetic separator to obtain sorting. It is mainly used for sorting ferrous metal ore ( iron , manganese , chromium ); it is also used for the selection of colored and rare metal ores.
4.Electrical selection method
Electroporation is based on the difference in mineral conductivity. When the mineral passes through the high-voltage electric field of the electric separator, the electrostatic force acting on the mineral is different due to the difference in the conductivity of the mineral, so that the mineral can be separated. Electroporation is used for the selection of rare metals, non-ferrous metals and non-metallic ores. Currently used mainly for the separation and selection of mixed coarse concentrates; such as the separation of white tungsten and cassiterite ; the selection of zircon , the selection of antimony ore.
Construction Hoist Steel Structure
Construction Hoist Steel Structure means the construction hoist spare parts like Construction Hoist Mast Section, Passenger Hoist Cage, Construction Hoist Wall Tie and so on.
The length of each mast section is 1508mm, the rack is fixed on the mast by three bolts and it can be exchanged. For the single cage hoist there is only one rack on the mast section, and the mast section can be used for the double cages hoist by increasing one rack. The section of the mast is diverse, select one type section according to different hoist. The mast sections are bolted together with M24 bolts and nuts to form mast. The mast is tied to the building with tie-in and is the guide rail of the cage. According to the user`s or circumstance`s request, surface of mast is hot dip galvanized, which can prevent it rusting.
The tie-in(wall tie) is the linked part between mast and building, to keep the stabilization of the mast. Distance between the tie-in is about 6~9m alone the mast. There are several types of tie-in. Select one of them according to need, tie-in can adjust the vertical of mast in definite ranges. According to the user`s or circumstance`s request, surface of the tie-in is hot dip galvanized, which can prevent it rusting.
The cage dimension(L×W×H)(m): 3×1.5×2.5. We can also manufacture cages of other size according to the user`s needs. The material of the cage and the door material can be steel wire weave, aluminum-plastic panel, punched-plate, figured aluminum board or other type according to user`s needs. The gate is equipped with drawing gate,include small turn over gate.
