Royston also noted new grates can slow milling rates some mills change every second grate at relines, while others use alternating high and low grate lifter bars, to maintain milling performance. The backflow of non discharged rocks can limit the pulp lifting performance and add to wear at the base of the pulp lifters.
Axial transport and grate Early work on ball mills by Mishra and Rajamani (1992, 1994) discharge have previously been studied for a ball mill with lifters has been followed by Cleary (1998, 2001a,b) and Cleary and Sawley that had a constant axial cross section in Cleary (2006). Long term (2002).

Jan 27, 2020 A comparison of SAG and ball mill charge actions is shown below. Figure 1 shows the sliding abrasion action of a ball mill while figure 2 depicts the cascading impact action of a SAG mill. The geometrical differences in the liner system lifters can also be seen. Figure 1 Sliding abrasion action in a Ball Mill.
In February 2006 the SAG mill ball charge was further increased to 13.5 . The combination of higher ball charge, relatively high speeds and inadequate lifter profile resulted in.
Abrasion resistance in ball mill. The consumption of ball mill steel is mainly caused by mechanical wear and corrosion wear, which is an irreversible process of quotphysicalmechanicalquot and quotphysicalchemicalquot occurring on the solid surface so on the premise of ensuring the quality of grinding the ball mill,how to reduce ball abrasion of ball mill change the grindability of ore.
Mill liners protect the mill shell from wear and transfer energy to the grinding charge. Careful balance is needed to optimise these differing requirements, as poor liner design has detrimental effects on milling performance – and on mill liner life.
The given liner designs and lifters, ball size and rock properties, and mill operating conditions. Based on the success of the 2 D model of the SAG mill, the 3 D model in DEM was developed. These types of models could help study charge motion, power draw, liners wear, and energy draft accurately [5,.
