California’s Spragues’ Ready Mix (SRM) has deployed the first closed-loop recycling equipment combination of its kind: A concrete reclaimer separating fine and coarse aggregate, coupled with a slurry-recycling filter that dewaters cement fines to yield nearly ASTM C-94 grade batch water (less than 60 ppm).
The company decided to purchase the Liebherr LRS 708 Concrete Reclaimer and ALAR Auto-Vac AV640-C® Slurry-Water Recycling Filter combination.
“The Liebherr/ALAR recycling system is exceeding our exacting needs for concrete and water reclamation. The systems have been easy to install and maintain by our own people,” affirms Steve Toland, Vice President & COO. “We look forward to years of doing our part for the environment and saving money in the process.”
The LRS 708 separates rock, sand and other aggregate materials, producing a clean, readily transported or recycled material.
The ALAR Auto-Vac® AV-640 dewaters cement slurry fines and color from the LRS Reclaimer, producing dry solids and clean, clear water.
Both systems can be sold and operated separately.
