The stroke rate may be 9/min when making separation at 200 mesh and up to 32/min for 28 mesh rapid settling sands. Widths range from 1 to 20 ft, lengths to 40 ft, capacity of 5–850 tons slurry/hr, loads from 0.5 to 150 HP. The solids content of the feed is not critical, and that of the overflow may be 2–20% or more.Section snippets Materials used. An antimonial refractory gold/silver ore sample obtained from Akoluk (Ordu-Turkey) was used in this work. The ore sample was crushed down to − 4 mm using jaw and rolls crushers, and riffled to obtain 1 kg representative sub-samples.These were then ground in laboratory rod mill at 50% pulp Optimization of some parameters of stirred mill for ultra-fine grinding
3.1 Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.Powder Technology 208 (2011) 121–127 Contents lists available at ScienceDirect Powder Technology j o u r n a l h o m e p a g e : w w w. e l s ev i e r. c o m / l o c a t e / p ow t e c Optimization of some parameters of stirred mill for ultra-fine grinding of refractory Au/Ag ores Oktay Celep a, Nevzat Aslan b, İbrahim Alp a,⁎, Gökhan Taşdemir a a Mining Optimization of some parameters of stirred mill for ultra-fine grinding
