ALS rectangular vibratory screeners are designed for control screening, classification, and dedusting of dry, granular, or powder materials, while also allowing material conveying along the screening surface.
This dual functionality makes them extremely versatile solutions for a wide range of industrial applications, including the food, plastics, chemical, and recycling industries.

Vibration is generated by two unbalanced motors operating at the same frequency, creating a linear motion of the product across the entire screening surface.
Adjustable eccentric masses allow the transport speed and hourly throughput to be regulated, ensuring a constant flow and efficient separation even when processing materials with different particle sizes or bulk densities.

The compact and modular design of ALS vibratory screeners enables optimal integration into existing plants, with the vibratory motors mounted underneath to reduce the overall machine width and facilitate maintenance operations.
Customizable discharge outlets—available in round or square versions and orientable to the left, right, downward, or forward—provide maximum installation flexibility.

Manufactured from high-quality steels (AISI 304, AISI 316 stainless steel, or painted carbon steel), ALS vibratory screeners ensure structural robustness, hygienic design, and long operating life.
Upon request, mirror-polished finishes are available, particularly suitable for food or pharmaceutical applications.

The screening decks can be equipped with stainless steel wire meshes or perforated plates in steel or polyurethane, depending on the processed material.
They can also be integrated with automatic cleaning systems such as bouncing balls, sliders, or brushes, maintaining consistent screening efficiency and reducing machine downtime.

Each ALS vibratory screener is custom-designed according to the customer’s technical and plant requirements, providing a reliable and tailored solution for bulk material handling in any production process.
