The pulp of Xinhai wet overflow ball mill overflow automatically, without forced discharge, which reduces the equipment wear and energy consumption, the discharging particle size is small, the qualified rate of grind size is improved, at the same time costs is under control.
Discharge of finer rock, pebbles, ball scats and slurry from mills and its flow through trommels and into other processing operations all affect the performance of overflow ball mills. Modelling of the coarser rock components and the grinding media is best done using the Discrete Element Method (DEM) while modelling of the slurry component is [.]
The discharging of wet type overflow ball mill relies on the inclination because of the outlet hollow shaft diameter larger than inlet hollow shaft diameter. When the slurry surface is higher than outlet generatrix, the slurry overflow discharges from the mill. Product principle

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
The same underlying model is used for SAG and ball milling, with minor differences for the way the charge density is calculated and whether the mill is a grate discharge (most of the SAG mills) or overflow discharge (typically a ball mill). Within the classification, there are also two versions of the Morrell C-model:
