Designed to remove clays, silts, organics and lightweight contaminants, Terex Washing Systems’ AggreScrub P80 allows operators to reduce operating costs, streamline plant design and improve final product quality.
Terex Washing Systems (TWS) introduced the new AggreScrub P80 log-washer with pre-screen at Hillhead 2026 this summer.
The AggreScrub P80 is a wet-processing solution engineered for construction and demolition waste, excavation material and aggregate applications.
Mounted on a single modular chassis, the plant combines pre‑screening, log-washer scrubbing, post-screening, contaminant removal, and slurry management within one integrated system, delivering efficient material separation while maximizing throughput and uptime.
“Introducing the AggreScrub P80 at Hillhead reflects the increasing demand for compact, high‑throughput wet-processing solutions capable of handling heavily contaminated material,” said Paul Carolan, Business Line Director for Terex Washing Systems.
“By combining pre‑screening, intensive scrubbing and accurate post‑scrub sizing on a single chassis, the P80 provides a practical way for operators to simplify plant layouts while achieving more-consistent, higher-quality end products.”
The AggreScrub P80’s modular, compact layout also supports faster transport, installation and commissioning, making it well suited as a core module within modern wet-processing plants.
PowerScrub
At the heart of the AggreScrub P80 is the PowerScrub twin‑shaft log-washer, featuring spiral‑arranged blades that deliver intensive stone‑on‑stone attrition and continuous material movement.
As well, an adjustable operating angle allows retention time to be optimized for varying feed conditions, while independent high‑torque drives allow reliable start‑up under load, helping to minimize blockages and downtime.

Following the scrubbing stage, material is processed by a 2.4-metre x 1.2-metre triple-deck inclined aggregate screen, producing up to three clean, washed products. Integrated spray bars deliver an effective secondary rinse to remove residual contamination prior to final sizing. Lightweight contaminants, including plastics and organics, are removed via a dedicated 1.8-metre x 60-cm trash screen, improving final product cleanliness and protecting downstream equipment.
An integrated sump tank and pump maintain consistent slurry levels to ensure stable washing conditions.
The AggreScrub P80 has also been designed with safety, durability and ease of maintenance in mind. Fully galvanized 80-cm-wide walkways with GRP flooring provide safe, non‑slip access throughout the plant, while robust wear protection and maintenance‑friendly access points support reliable operation in demanding environments.
At Hillhead, TWS also showcased its FM60C from their FM Compact, which is designed to deliver cost and energy‑efficient sand recovery by using centrifugal force within hydrocyclones to remove clay, silt and slime below 75 microns.
The FM60C, which combines a collection tank, centrifugal slurry pump, hydrocyclones and a high‑frequency dewatering screen on a single compact chassis, can recover one or two grades of sand with low residual moisture content in the final product. “The first public showing of the AggreScrub P80 at Hillhead, alongside the FM60C sand-recovery unit, reflects key elements of our wet-processing capability,” Carolan said.
