Astec
Astec Industries announced the launch of its Vari-Frequency technology implemented on our 6203 LP Horizontal Screen, a solution built to boost screening performance. The new design minimizes blinding and maximizes uptime, giving producers a smarter, more reliable way to keep processing material.
Cable-Supported Deck Generates Vibrations for Screening
Installed on the bottom deck of a horizontal screen, the vari-frequency deck significantly increases throughput and efficiency while minimizing plugging and blinding — two of the most common challenges in screening operations. The live portion of the deck's flexible surface is supported by a system of tensioned cables that create rapid, localized g-force spikes across the screen, stimulating the screen media and material to maintain throughput.
"This launch represents a major step forward for producers who want to increase throughput without adding complexity," said Michael Norris, group president, materials solutions, Astec. "The addition of vari-frequency technology on horizontal screens gives customers a smarter, more productive way to process material even in demanding applications. It's another example of how Astec is bringing industry-changing solutions to the market, and we're excited to expand this technology across more of our screening lineup. We can't wait to showcase the 8-ft model at ConExpo-Con/AGG 2026."
Built for standard side-tensioned screen cloth and requiring no external power source, the vari-frequency technology provides an adaptable, energy-independent solution that integrates into existing systems, according to Astec. Its development was driven by testing and customer collaboration to ensure performance in demanding conditions.
"The screen has been a total game changer for our production," said Damon Eggert, operations manager of Perkins Cinders. "It's had a huge impact on our output and what we've been able to accomplish on site. The efficiency it brought allowed us to get more done, faster."
Key Features of Astec Vari-Frequency Horizontal Screen
• Increased efficiency and throughput: New deck design delivers significantly higher throughput.
• Reduced blinding: Flexible, cable-supported deck generates screen media vibration spikes to minimize buildup.
• Low maintenance: Cleaner screen media reduces the need to climb between decks for manual cleaning and downtime.
• Energy independent: Operates without external power for cost-effective performance.
• Seamless integration: Screens with vari-frequency technology will be interchangeable with standard units requiring replacement or a performance upgrade.
As part of Astec's broader commitment to continuous innovation, the company plans to incorporate vari-frequency technology into additional screen models across its robust product portfolio. Attendees of ConExpo-Con/AGG 2026 will have the opportunity to preview the 8-ft. model, the next piece of equipment in the technology rollout.
The vari-frequency horizontal screen continues Astec's legacy of designing durable, practical and forward-thinking equipment that meets the evolving needs of producers worldwide.
