Underwater screen

Screening technology

special screen for wet screening

IFE underwater screens with IFE exciter drive work in a tank. The screen deck is partially submerged. Excellent screening results are the result of the flow behavior of water, particularily when fine cutpoints are needed

screening in the water
Product Highlights.



300 t/h of iron ore are a challenge to be screened at a cutpoint of 2 mm using conventional screening technology. It can be done easily by using underwater screens, where the screen deck is submerged partially. The flow behavior of water and water pressure above and below the deck moves fine particles through the screen deck, achieving excellent screening efficiency. Underwater screens are proof for the wide range of products of IFE screening technology - the combination of robust design and appication know-how guarantees client satisfaction.

IFE exciter drives from our own production are manufactured using first-class components and  feature maximized lifetime of the bearings. Decades of experience in designing these screens results in optimized and adequate excitation and maximized efficiency. The screen can be accelerated up to 6g and still boast bearing lifetimes of 100.000 hours or more.Highest reliability, even in harsh conditions, is the proven result.
