vertical stirred mills have been reported to use up to 40 percent less energy (decreasing to 20 percent for coarser applications p80200m) and 20 percent less media than equivalent ball mills. however, this reduction is difficult to validate in operations as there is a tendency for these circuits to create a sharper product size distribution
jun 08, 2021 where u is the velocity vector, t the time, p the static pressure, the kinematic viscosity, x (x, y, z) the position vector, and finally is the angular velocity vector of the inertial coordinates. in the present case, this vector has a nonzero component only in the axial z direction, that is, (0, 0, ), which indicates that the rotation takes place in the (x, y) plane and is
this study focused on the comparison of vertical stirred mill agitator designs. a double helical screw agitator was designed for this purpose. a series of stirred mill experiments were performed with two types of agitator designs a standard pin type and csiros designed double helical screw stirrers.
feb 22, 2016 outotec vertical stirred mills do the job for kevitsa. in 2012, kevitsa, a first quantum (fqm) copper-nickel-platinum mine in finland, began production with throughputs of about 5 mt/y. the original scope included a grinding circuit consisting of two ag mills and a secondary pebble mill, with successive copper and nickel flotation to produce
1.1 grinding mechanism of a vertical mill with vane rotors stm/outotecs higmill is a stirred media grinding mill where the stirred effect is caused by rotating vane grinding discs (rotors) together with stator rings situated on the shell.
