“The equipment 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% 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 saleable manufactured sand with, Superior claims, just 8% moisture content. Superior manufactures models of its new Alliance Low Water Washer for rates up to 272tonnes/hour. Custom-designed machines can produce higher rates if required, the company states.
