RA-20 / RA-6

SPECIFICATIONS

Schwing engineers introduced the washing drum principle reclaimer in 1976 to achieve 100% recycling of aggregates, sand and gray water. It has proven popular with U.S. producers for its low water consumption, low wear and minimal maintenance. The quality of the reclaimed aggregates and the cut-size of sand fines that are washed out with the gray water are unsurpassed. Models include the RA-20 with processing of up to 30 cu.yds/hr. and the RA-6 with 8 yds./hr. capacity. Options include complete gray water reuse packages, surge hoppers for rapid loading of up to 10 yds of concrete and a slide gate system to prevent overloading. Customers receive detailed plans for installation and customization to fit specific requirements.
