POWER AND PRECISION COMBINE IN THE ALL-NEW ASTEC VARI-FREQUENCY HORIZONTAL SCREEN

ASTEC Industries has once again raised the bar in material processing technology with the launch of its new Vari-Frequency Horizontal Screen, a groundbreaking addition to its family of high-performance screening solutions.

Engineered to provide superior adaptability, efficiency, and throughput, the ASTEC Vari-Frequency design allows operators to fine-tune vibration frequency to match the specific characteristics of the material being processed — ensuring optimal performance across a wide range of applications.

Available through Tracey Road Equipment, this innovation underscores ASTEC’s ongoing commitment to helping producers work smarter, reduce downtime, and achieve more consistent results across every load.

Game-Changing Versatility — Astec’s New Vari-Frequency Horizontal Screen

ASTEC Industries announces the launch of its groundbreaking Vari-Frequency™ technology implemented on our 6203 LP Horizontal Screen, a next-generation 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.

What Is the ASTEC Vari-Frequency Horizontal Screen?

The ASTEC Vari-Frequency Horizontal Screen is a state-of-the-art screening solution that gives producers unprecedented control over their material processing.

Unlike conventional fixed-speed horizontal screens, this system allows operators to adjust vibration frequency on demand, ensuring ideal separation, reduced blinding, and higher throughput — no matter the material type or gradation.

Key Specifications:

  • Adjustable Frequency Range: Fine-tune vibration from low to high RPM for variable materials.

  • Optimized Efficiency: Match screen performance to particle size and feed consistency.

  • Enhanced Durability: Built with ASTEC’s heavy-duty design for long-term reliability.

  • Compatibility: Designed for both portable and stationary applications.

This adaptability makes it the ideal choice for aggregate producers, recyclers, and asphalt operations seeking to maximize precision and uptime in changing material conditions.

The Technology Behind Vari-Frequency

Traditional horizontal screens operate at a fixed vibration frequency, meaning they perform best under specific material conditions — often forcing operators to compromise between speed, accuracy, and product quality.

The ASTEC Vari-Frequency system eliminates that compromise. Its variable drive control allows operators to adjust vibration speed in real time, optimizing performance for every feed type — from wet, sticky clay-based material to dry aggregates.

How It Works:

  • Adjusting vibration frequency changes how material stratifies across the deck.

  • Lower frequencies provide more aggressive material movement, ideal for coarse screening or wet conditions.

  • Higher frequencies increase fine material separation and improve accuracy for dry feeds.

  • This flexibility reduces downtime, prevents clogging, and improves overall screening quality.

In essence, one screen can now do the work of multiple machines, adapting instantly to jobsite needs.

Designed for Performance and Reliability

As with every ASTEC product, the Vari-Frequency Horizontal Screen is built for real-world demands. From quarry operations to asphalt production, it provides the durability and uptime that producers expect from the ASTEC name.

Performance Features Include:

  • Precision Control System: Easy-to-use interface for fine-tuning vibration speed.

  • High-Capacity Deck Design: Maximizes screening area and material flow.

  • Rugged Frame Construction: Built with reinforced side plates for long service life.

  • Maintenance-Friendly Layout: Simplified access points for fast adjustments and inspections.

Combined, these features deliver consistent material quality, longer wear life, and lower total cost of ownership — making the Vari-Frequency screen an investment in long-term efficiency.

Applications Across Industries

The versatility of the ASTEC Vari-Frequency system makes it valuable across multiple segments of the material processing industry:

IndustryApplicationKey Benefits
