Superior Industries, Inc. launched a new solution within its line of washing and classifying machinery, which processes crusher fines right next to the crushing circuit. Known as the Alliance Low Water Washer, the unit accepts a dry feed directly from the crushing circuit and processes the material into higher value manufactured sand.
“The equipment washes and process these fines and creates another source of income for the owner,” says John Bennington, director of washing and classifying at Superior Industries. “Historically, all of the machinery used to wash crusher fines has been the same design as sand washing equipment. The Alliance Low Water Washer is designed specifically for washing crusher fines and uses 80 percent less water than the traditional screw/screen combination.”
The agitator section is positioned at the front end of the screen where water is added to the dry feed and mixed, producing a thick slurry. This slurry is then dumped onto a dewatering screen with a series of spray bars to help clean and wash out the fines. The end result is a salable manufactured sand with just 8 percent moisture content.
Superior manufactures models of its new Alliance Low Water Washer for rates up to 300 tph (272 mtph). Custom-designed machines can produce higher rates if required.
