Metso Stirred Media Detritors (SMD)

Overview
The Metso stirred media detritor (SMD) has proven effective in producing fine and ultra fine product size for a wide range of metalliferous feeds. Feed size is typically 80% passing 100 µm and finer, but can handle coarser in various applications.

A wide range of feed slurry solids concentrations can be accommodated, typically in a range of 30-60% w/w. 

The normal operating range is 20-100 kWhr/ton, which meets the majority of metalliferous fine and ultra fine grinding requirements. 

SMDs are currently available with an installed power up to 1100 kW.

• Low installation cost
