At Teck CDA the ore extracted in the open pit mine is sent to three pre-crushing plants, with a total capacity of 58,000 tonnes/day. One of these plants, with a capacity of 20,000 tonnes/day, is fed with high moisture content mineral. This, together with the addition of water as a dust suppressant, produces accumulation and compaction of fine ore in different equipment and plant structures.
Objetive and Scope
Identify technological solutions to:
Equipment cleaning takes around 30 minutes and is performed 3 times a day, which represents 12% of the total shutdowns of precrushing plant with a capacity pf 20.000 tonnes/day. The aim is to reduce cleaning shutdowns by at least 50%.
When does the problem occur?
How is it currently resolved?
Plant is shutdown and a team of workers perform a manual cleaning.
Technological solutions have not been tested.
