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.
A) Total Apparent Volumetric Charge Filling including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume (inside liners). B) Overflow Discharge Mills operating at low ball fillings slurry may accumulate on top of the ball
The number of balls having the determined diameter in a mill depends on the ball size distribution in the charge. Let us suppose that the ball size distribution in the charge can also be depicted by GaudinSchumanns equation c b b d d Y ¸¸ ¹ · ¨¨ © § max d bmin <d <d max (9) where Y is the load of the balls having diameters less than d b d b
(1) Based on grain size hardness material grindability and the product fineness requirements we can determine ball gradation. When material grain size is small and fineness requirement high we need to choose small size steel ball to strengthen material grinding. Conversely if the material grain size is large what we need to do firstly is to crush them then we would better to use large size grinding ball.
