It's common for fines to stack up at operations across our industry, often viewed as a byproduct with limited value.
At CONEXPO-CON/AGG, Superior will introduce a new portable plant built to address that challenge, giving dealers another solution to help turn fine material into saleable product.
“A lot of operations are sitting on fines they haven’t fully monetized,” McKinney says. “The Independence™ High Frequency Screen (HFS) Plant is designed to help them recover that material and create a cleaner, higher-grade product.”

Ideal for processing 1/4"-minus material and capable up to 3/8"-minus, the unit features a 36" feed conveyor and the screen set at 37°, which keeps material moving for a high material grade.
“Additionally, the dual-axle chassis and Honda-powered hydraulic unit make setup straightforward,” McKinney says. “With a 36-inch stroke cylinder, the plant lifts straight into position and pairs nicely with our Slide-Pac™ or Slide-Stac™ Conveyors.”
Material from the feed conveyor hits a vibrating feed distribution box that’s designed to spread it evenly across the deck. This helps to maximize screen utilization from the start.
The plant’s multi-slope design and 6 x 20 deck deliver screening area and performance comparable to larger units on the market, bringing high-capacity fine separation to a portable platform.
Superior’s design allows independent speed control by deck or motor, giving producers exceptional command over separation performance.
“Operators will appreciate the high level of adjustability,” says Cody Tufford, vibratory product manager. “They can increase or decrease frequency based on the application very easily.”
With electric motors mounted externally on the screen, operators can safely adjust performance without climbing inside the machine.
An automated clean-out feature, standard on the Independence High Frequency Screen but not common in the industry, can help extend the lifespan of the screen media too.
“You can program intermittent clean-out cycles,” McKinney says. “If material gets sticky or the media starts to clog, the system ramps up to 6,000 rpm for about 20 seconds, then returns to normal operating speed.”
In designing the high frequency screen, Tufford says Superior placed a strong emphasis on maintenance.
That means, instead of tensioning wire media from the outside like many competitor models, the Independence HFS uses quick clamps that are accessible at the feed and discharge ends. This allows operators to apply more uniform tension across the width of the wire.
Beyond performance and maintenance, the Independence HFS introduces a patent-pending feature: always-level walkways.
“As the screen goes up to 37 degrees, the stairs and rear platform stay level the entire time,” McKinney says. “When it’s down for transport they're flat, and when it’s up for operation they're still flat, making it much safer and easier to work around.”
With safety, maintenance access, and usability built in, the high frequency screen will provide Superior dealers with a plant that can deliver value in a variety of ways.
“There’s just such a wide range of opportunities for this screen," McKinney says. "“It covers fines removal, manufactured and frac sands, while also opening doors in roofing, agriculture and industrial mineral applications.”
From Tufford’s perspective, the Independence it can serve as a washing alternative in certain dry applications.
“In situations where water availability is limited or producers want to avoid complexity, a high frequency screen can provide fine separation without the need for a wash plant,” he says.
