McLanahan UltraSCREEN: Modular Horizontal Screen for Wet or Dry Sizing

McLanahan has added the UltraSCREEN Horizontal Screen to its Ultra line of modular processing equipment, giving aggregate producers a pre-engineered screening plant that can be dropped into both new and existing sites with minimal site work.

The UltraSCREEN is built on McLanahan's triple-shaft horizontal screen technology and is designed to size and separate up to three classified products plus one non-classified product. It ships as a compact package with an included support structure, an unrestricted full-access service platform and a configurable stairway, so producers can place it alongside existing crushers or conveyors without redesigning the circuit.

McLanahan positions the unit for rapid delivery and fast installation: it arrives pre-plumbed, requires minimal wiring, and is meant to be up and running quickly in the field. Buyers can choose 6- x 20-ft., 7- x 20-ft. or 8- x 20-ft. three-deck configurations, and each unit can be set up for wet or dry applications, covering everything from dry scalping and sizing to washing circuits.

Service access is a deliberate design theme. A standard rollaway discharge chute can be rolled back so the working platform lowers and locks for safe deck access, which matters when crews are replacing screen media, checking tension rails or clearing pegging on the top deck. Integrated flop gates inside the chute let operators blend bypass material with upper-deck product before it reaches the discharge conveyor, tightening product consistency without extra conveyors.

What buyers should check before specifying a modular screen

For overseas buyers comparing modular screening plants, the practical checklist starts with deck size and count: three-deck units in the 6x20 to 8x20 range set the top feed size and total tons per hour, while the triple-shaft mechanism determines how aggressively material travels across the media. Wet applications add spray bars, pumps and water supply requirements that should be quoted up front.

Wear and spare parts availability is the other long-term cost driver. Screen media, springs, bearings and shaft assemblies are the components that cycle out fastest on a screening plant, so confirm that media in the sizes and aperture types your product mix needs can be sourced locally or shipped quickly. For used-plant shoppers, a modular unit with documented support structure and access platforms, like the UltraSCREEN concept, is generally easier to relocate and re-commission than a site-built screen tower.
