Astec Industries has launched its groundbreaking Vari-Frequency technology, implemented on its 6203 LP horizontal screen.
The next-generation solution is built to boost screening performance by minimizes blinding and maximizes uptime, giving producers a smarter, more reliable way to keep processing material.
Installed on the bottom deck of a horizontal screen, the patented Vari-Frequency deck 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.
Astec will showcase its 2.4 metre model at ConExpo 2026.
“This launch represents a major step forward for producers who want to increase throughput without adding complexity. The addition of Vari-Frequency Technology on horizontal screens gives customers a smarter, more productive way to process material even in demanding applications,” said Michael Norris, Group President, Materials Solutions, Astec.
“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.”
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.
Its development was driven by extensive testing and customer collaboration to ensure reliable performance in demanding conditions.
“The screen has been a total game changer for our production. 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,” said Damon Eggert, Operations Manager at Perkins Cinders.
Astec Vari-Frequency key features
- Increased efficiency and throughput: Innovative 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 innovation, the company plans to incorporate Vari-Frequency technology into additional screen models across its robust product portfolio.
