thickener torque rakes & drive

a little earlier i talked about the rakes of the thickener these are long arms that extend off of the bottom of the drive shaft. as the shaft turns the rakes will sweep the entire bed of the thickener thereby applied torque. each rake arm is higher at its far end than it is where it joins the drive shaft. this is designed this way to give the bed a slope towards the centre of the thickener.

solidliquid separationsciencedirect

whenever feasible solids are settled out by gravity or with the aid of centrifugation. in dense media separation like ore separations an essentially homogeneous liquid phase is made by mixing in finely divided solids less than 100 mesh of high density; specific gravity of 2.5 can be attained with magnetite and 3.3 with ferrosilicon.
