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.
There are several different processes used to achieve sludge thickening such as gravity thickeners gravity belt thickeners (GBTs) rotary drum thickeners (RDTs) centrifugal thickening and dissolved air flotation (DAF) thickening. Process configuration energy consumption chemical and labor requirements and the extent of thickening achievable vary among different thickening methods.
When wastewater is treated sludge is produced. Ovivo thickeners are designed to continuously produce as thick a sludge as possible. Powered by heavyduty drives designed to handle the specified torque for 20 years of continuous operation the sludge is gently mixed by rotating rake arms. This movement keeps it moving towards the center of the
Sludge is introduced at a central feed well and the supernatant overflows a peripheral . The sludge is thickened by the action of a specially designed rake which also moves the thickened sludge to a central hopper of included angle 60° for intermittent discharge under hydrostatic head ( Albertson 1992 ).
Sludge is usually pumped continuously from the settling tank to the thickener which has a low overflow rate so that the excess water overflows and the sludge solids concentrate in the bottom. A blanket of sludge is maintained by controlled removal which may be continuous at a low rate.
Thus the solids load entering the sludge thickener becomes 112.1 The solids load escaping in the liquid portion from the thickener is taken as 11.2 The solids load leaving the thickener becomes 100.9. In the dewatering centrifuge solids load from polyelectrolyte is 0.8
