Gross power calculator general depends on whether the mill is an overflow or a grate discharge machine in all cases ag and sag mills 2 are grate discharge and ball mills are mostly overflow a few however are grate discharge in overflow,ball mill overflow grate power.

Ball mill overflow grate power

Overflow ball mill is a kind of ball grinding mill which works in wet water state. it belongs to a type of wet ball mill and is a very common grinding equipment in the concentrator. ball grinding mills are classified according to the discharge methods and can be divided into overflow ball mill and grate ball mill.Sag mill liners for discharge grate special features: the material of sag mill liner castings are low c or high c cr-mo alloy steel,which depends on the specific working condition of the sag mill. the hardness of as2074 l2b is hb310-hb380. we can make big size sag mill liner castings with sodium silicate sand process & resin sand process.The grate ball mill is roughly composed of the cylinder, cylinder liner,big gear ring, discharging grate,and ore feeding device. except there is a discharging grate plate installed at the discharging end, all the other is similar with the overflow ball mill.

Milling discharging. wet milling has several advantages including easy discharging. simply rotate the mill with the discharge grate point down and open the valve. dry milling has advantages including reduce reactivity and ease of handling the dry solids. with a few design changes, dry discharging is simple and contained.Nov 01, 2006 we use a simple model for grate discharge that allows prediction of the time varying axial distribution of different particle sizes within a discharging ball mill. the distributions of sub-grate size ‘fines’ is shown to satisfy a one-dimensional diffusion equation with the diffusion coefficient decreasing with grate size.
