Grate Ball Mill W orking principle Grate Ball Mill is the horizontal tube rotating device, outer edge of the gear drive, two chambers, and lattice-type. Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills to choose. IV.
Ball Mills Steel Ball Mills & Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis.

A pulp lifter for a grate discharge mill used primarily in mining operations. The lifter comprises a plurality of chambers which radiate outwards. Each chamber comprises a transitional compartment (2) having apertures (19) into which the slurry enters and a collection compartment (21) to which the slurry passes. When the pulp lifter rotates, the slurry cannot flow back but …

size distributions in AG/SAG mills. The existing models and understanding of grate discharge and classification are known to be flawed and have been identified as one of the key limitations in AG/SAG modelling. The aim of this thesis is to improve on the current understanding of discharge in the SAG/AG model.
This requires simulation of the entire mill and the full volume of the charge for significant periods of time (thousands of revolutions). 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
