A classifier equipment with overflow end spiral completely submerged below the liquid surface.
Xinhai tailings dry stacking technology is mainly applied to the dewatering and concentrating of mineral tailings in the mineral processing plants. To reach the aim of tailings dry stacking and avoiding environmental pollution, it is the essential technology of green mine.
Phosphate Flotation Product Line is applied for complex structure phosphate with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
Barite is fragile and like a big tube. The separation methods of Xinhai are generally gravity separation, magnetic separation and flotation.
Alluvial gold processing solution mainly applies to processing alluvial gold with a large volume of gangue minerals. Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc.
Figure 9.2 shows a permanent magnetic drum separator which consists mainly of a permanent magnet system a rotating drum a separating chute a feed tank and a flushing pipe.For magnetite separation the magnetic field intensity on the surface of the drum is between 0.1 and 0.4 T. However for other applications the intensity may reach as high as 0.8 T.
the benchmark for wet drum performance. The culmination of various inplant tests has demonstrated that the separators will achieve magnetite recoveries in the 99.9+ percent. (This is based on magnetite losses of less than 1 gram/gallon of nonmagnetic effluent). The Eriez Wet Drum Magnetic Separators utilized the 950 gauss
For lowintensity drum separators used in the iron ore industry the standard field for a separator with ferritebased magnets is 0.12 T at a distance of 50 mm from the drum surface. Work has also shown that such separators have maximum field strengths on the drum surface of less than 0.3 T.
of the magnets. Most wet drum magnetic separators are of the type with ceramic ferrite magnets generating a field strength between 1 500 and 2 500 gauss. Rare earth wet drum magnetic drum separators have rare earth based magnets generating a field strength between 3 000 and 10 000 gauss. The field strengths are measured at the surface of the drum.
