Lifecycle Vibrating Screen Parts (4 replies)

Want to know how long your vibrating screen elements can last without shut down and any maintenance. Interested in SAG mill that does not have a trommel screen and mill size is as large as possible (such as 36' to 40' diameter).

Under a 24/7 operation and an output of 50.000 metric ton a day, 3 months if you are lucky!

The screen elements life depends mostly in the type of material that the element is made of. There is an approximately relation between thickness of the elements and the lasting of them. Manufacturers can fabricate them depending on how long you want the elements last, if they have a product of good quality!

Manufacturers can modify open area, thickness, design, etc. so the elements can last as long as you want, keeping operational parameters.

I agree with you, durability mainly depends on quality of material used and also on the frequency set on the vibrating screen motors. In my case our, with a throughput of 6500 tons a day we change scalping screen panels after 3 months but continuous checks being done on monthly shutdowns. Screen aperture and amount of spray water are also important parameters to be checked for better results.

In my experience the main factor is the material quality of screens. By frequency you mean stroke?
3 months for a 6500 ton/day is a very low durability, they are metallic, rubber or polyurethane? Which is the size of the slot? generally the slots have a 7º concavity to avoid rocks jamming, that`s mainly why the slots tend to "open", so the better material the less the slots open, and last longer. Hope this will help.
