Stirred media detritors
The Metso stirred media detritor (SMD) has proven effective in producing fine and ultra fine product size for a wide range of metalliferous feeds. Typical feed size is in the range of 30-100um.
A wide range of feed slurry solids concentrations can be accommodated, typically in a range of 20-60% w/w.
The normal operating range is 20-100 kWhrs/ton, which meets the majority of metalliferous fine and ultra fine grinding requirements.
Maximum size for a top screen SMD is an installed 1,100 kW.
Design enhancements include improve power efficiency with the following advantages…
