Mining Application
Case Study of Working Urethane Trommel Screens
A gold mine in northern Ontario Canada, milling 6,000 tons/day has two Ball
Mills that are 16' x 21' with 41 3/4" I.D. x 83 1/8" long trommel screens
installed to catch tramp steel to protect pumps and ceramic lined cyclones.
They tried punched plate but found it wore out very fast from both corrosion
and abrasion.
Then they went to punched rubber with steel backing, but it very quickly
plugged with near size particles and had to be removed frequently. They installed
Durex modular urethane trommel screens and found virtually no plugging. Durex
urethane screen surfaces are expected to provide 5 times the life of punched
plate.
