Ore Dressing Sympatec

Typical particle size distributions measured at the discharge section of an SAG mill for pre-crushing, and at the mill output of the final ball mill (concentrate) The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore.

AG & SAG Mill for Mineral Processing Wet & Aerofall

AG mill (autogenous mill) is a medium-free mineral grinding equipment. The raw ore and the coarsely crushed ore are directly fed into the AG mill. No other medium is involved in grinding. Only the impact between the ore is used for self-grinding. The ore larger than 100mm in the AG mill plays the role of grinding medium.

Investigation of the effect of filling level on the wear

2021-5-9  For a static SAG mill, the increase in the ore filling level means that more particles will contact with the liner, but that may not apply for a rotating SAG mill. When a particle contacts with the liner and then leaves, it is counted as a collision in our research. And the collision frequency is the total number of collisions per second.

Comminution Circuits for Gold Ore Processing

2016-1-1  Such a circuit can counteract the effects of harder ore, coarser ore, decrease the size of SAG mill required, or rectify poor throughput due to an undersized SAG circuit. Notably, harder ore often presents itself to the SAG circuit as coarser than softer ore—less comminution is produced in blasting and primary crushing, and therefore the impact on SAG throughput is compounded.

Grinding Mineral Processing

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.
