Greensand caught in cyclone
15 Jan 2000
Alfer reduced disposal costs at its Preston foundry with the installation of Donaldson filtration equipment.
The foundry's recovery plant used a wet collector for dust extraction with only poor efficiency. Using Donaldson's Torit technology with its DFT4-128 Downflo II dust collector with separator cyclones to remove large particles, provided over 60,000cfm greensand removal at 99.999 per cent efficiency at 0.5 micro m. Savings came by using dry collection instead of wet and reduced downtime while dust is recirculated into the sand plant.
