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.

Advantages

Design enhancements include improve power efficiency with the following advantages…

• Open circuit operation
• Mechanically simple design
• Competitive capital cost
• Use of low cost, ceramic, natural silica sand or pebble media
• No steel contamination of product
• Capacity to operate continuously at full load power draw
• Low rotational impeller speed with shallow charge depth providing reduced abrasion of impeller and body liner coverings
