Semi-autogenous (SAG) mills are widely used grinding equipment, but some ore with critical particle sizes cannot be effectively processed by SAG mills and turned into pebbles. This research aims to analyze and compare the properties of raw ore and pebbles from a zinc- and tin-bearing ore. The results show that the contents of sphalerite, …

The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally, the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research, a two-input-two-output model was applied to describe the system, in which some key indicators of …

Application 1. Grinding Mill Systems Grinding mills are crucial to mineral processing operations. As lower quality ore bodies are tapped, the tonnage processed per ounce of salable material will increase. This degradation in ore quality requires more power in the mill circuit, meaning larger motors and drives.

In large-size SAG mills (1158.24–1219.2 cm in diameter), ball fracturing can account for a higher percentage of consumption due to increased impact energies. In these cases, the ball quality becomes more important. Balls that are deformed can clog the exit grates of the SAG mill (see Fig. 15c), leading to unplanned maintenance. The chemical ...

Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (e.g., a 34-ft-diameter mill shell would have 68 shell lifters). This is also called a 2-D shell lining. Eliminating some shell lifters increases the volume of charge between the lifters
