Cavex® reduces circulating load by 246%

The Challenge

• Incumbent cyclones couldn't cope with expansion to plant 
• Cyclone feed density exceeded cyclone capabilities
• As much as 700% circulating load

Our Solution

• Cluster of 15" Cavex® 400CVX10 hydrocyclones
• Finely tuned spigot liner diameters to improve performance
• Ideal for high hydrocyclone feed densities

The Results

• Circulating load was reduced from 620% to 374%
• Direct savings of more than US$815,000 per annum

Summary

The Didipio mine, which employs more than 1,500 workers (drawn predominantly from the local community) expanded its production capacity, which increased the incumbent cyclones’ feed density beyond what they could effectively manage, leading to a circulating load of up to 700%.

The Cavex^® 400CVX10 hydrocyclones significantly improved separation efficiency due to their finely tuned spigot liner diameter, and the strength and corrosion resistance provided by its cast housing.

Thanks to these qualities, the introduction of the Cavex^® hydrocyclones reduced the circulating load from 620% to 374%. The direct savings in power consumption, ball consumption, cyclone and pump maintenance costs exceed US$815,000 per annum.
