  • Prediction of 3D slurry flow within the grinding chamber

    Slurry flow including flow through the charge in the grinding chamber through the discharge grates along the pulp lifters and its discharge from the mill is an important contributor to the efficiency of the grinding process within a SAG mill. Poor transport of finer ground material can adversely affect grinding leading to excess energy consumption

  • How a Grate Discharge Ball Mill Works911 Metallurgist

       Each time the grate enters the mill charge the horizontal force of the load in the mill deflects the grate. This stretches the rubber and forces any large material caught in the grate opening along through the grate slot. As the grate leaves the charge the rubber assumes its original shape.

       fluid pulp into the pulp lifter. In mills with no slurry pool the position in the mill rotation where most transfer takes place is around halfway between the toe and shoulder. Inside the "eye" the loose open structure of falling mill-charge presents little pulp to the grate. It follows that to be effective in receiving fluid pulp grate openings should be positioned from the "eye-line" "outwards." In practice the outermost grate openings (i.e. those nearest the shell) appear to be the most effective for the transfer of pulp hence it is important to maximize the open area in the outer part of the grate. Nevertheless the inner openings can be important for charge transfer with new grates that have smaller outer open areas compared to worn.For the efficient and effective performance of grates and pulp lifters it is important to recognize the impact of "pulp reverse-flow" and the interaction between grate

       The design of mill liners and SAG mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput. All models generally assume that a mill is fitted with "efficient" liners and that the grate design neither limits passage of pebbles (and pulp) nor permits re-circulation of pulp back into the mill.
