Elkhart County Gravel, headquartered in New Paris, Ind., operates four Indiana and Illinois Department of Transportation certified sand and gravel pits in northern Indiana that produce landscape stone, asphalt blends and concrete mined from a bench below water. As plant manager, Arnie Miller knows the value of investing in products that save money and increase plant production, which is why he partnered with Durex.

"We've used Durex from day one. I've been buying screens from them for 35 years," said Miller.

Bryant Fazer, president of Rock Machinery — Durex's dealer — knows why so many producers choose to work with Durex.

"What's unique to us is everything is 100 percent manufactured in-house. The raw wire is purchased domestically and not overseas," said Fazer. "Durex has complete control over its process and the skill to make the best products in the industry."

Increasing Wear Life With Armor Screens

Elkhart County Gravel uses a variety of Durex products, from modular urethane panels to long slot triple shoot woven wire screens and Armor screens. The Armor screens are where Elkhart has found an incredible improvement in durability.

Built from high-grade wire cloth and modeled open-cast premium polyurethane, these tensioned screens offer a much higher open area than conventional polyurethane screens and much longer wear life than wire screens. Users get all the benefits of a side tension panel without having to convert their deck to a modular system.

Built to install like wire screen panels, an Armor screen requires no modification and stands up to highly abrasive wear in light to medium load application wash plants like Elkhart.

"They work great and wear better," said Miller. "We were using four to five wire panels a year and last year we went through a full season with just one Armor screen."

Increasing Plant Efficiency

Miller also implemented long slot triple shoot wire screens at the Elkhart plant due to the increase in efficiency they offer. Made of high-quality XT, oil-tempered, stainless or high carbon steel, Durex woven wire screen allows the use of lighter-gauge wire, and the long slot triple shoot wire cloth reduces plugging and binding.

When vibration is applied to longer unsupported wires, it helps to eject material that might plug or close openings. In addition, these screens are crimped specifically to provide better sizing accuracy.

"The stones don't block your screens and the material can go through — they work fantastically," said Miller.

And Miller would know, given that he had to deal with major plugging problems before making the switch to Durex.

"When I started here, we'd run a 1/8-inch square wire screen and I'd have to go out there with an ice pick and hammer to punch all the little stones out of a million holes."

With everything being made in-house, Durex can make screens to client specification in a wide range of slotted openings and even manufactured in a "flat-top" weave for more uniform wear.
