Semiautogenous (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 tinbearing ore. The results show that the contents of sphalerite, cassiterite, biotite, antigorite, pyroxferroite ...

Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semiautogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushinggrinding circuit with three stages of crushing followed by ball mills or ...

Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge.
