SAG Mill Grinding Circuit Design

For circuits classifying mill discharge at a coarse size (coarser than approximately 10 mm), trommels can also be considered to classify mill discharge. Trommels are less favorable in applications requiring high classification efficiencies and can be constrained by available surface area for high-throughput mills. Regardless of …

Slurry flow in mills: grate-only discharge mechanism (Part-1)

Typically in wet overflow grinding mills the product is allowed to exit the mill by overflowing the discharge trunnion. The driving force for flow of slurry from the feed to discharge end of the mill is the flow gradient due to the discharge trunnion being larger than the feed trunnion. However, grate discharge mills have a more complex mechanism.
