An accelerated screening action cleans material without water, thus reducing water use at an operation where the product is used. The company also said the polyurethane media can reduce or even eliminate the need for a rinse screen.

Specifically, Ty-Deck Ultra screens have H-shaped openings with individual strips of polyurethane; each opening is separated by two parallel independent extensions.

Material acceleration is achieved with the strips vibrating independently, which also improves material separation and cleanliness. The strips' rapid movement also eliminates pegging and blinding.

"[It is ideal] for mining operations seeking more sustainable options in applications requiring production increases combined with high abrasion resistance," it said, adding that it is also a good choice for screening ores, especially on a vibrating screen's second deck.

Managing director for the company's Brazil operation, Clayton Carvalho, said the screen was designed using customer feedback which indidated a need for screen media that eliminates the use of water.

"Recent events have made it clear that there is a high possibility of producers facing water restrictions or bans. We want to offer operations a solution so that they can maintain production, as well as provide a positive environmental impact by virtually eliminating the use of water with Ty-Deck Ultra," he said.

Ty-Deck Ultra can be used for handling abrasives with a top size of 50 millimeters on the second deck in non-impact areas. The polyurethane is poured open cast, so it will permanently harden when cured - which maintains its chemical properties and permits users to have 1.5-2 times longer wear life than injection molded screen media.
