RA-20 reclaimer recycles 100 percent of ready-mix, according to Schwing, with a rotating drum design that washes returned concrete. A screen separates sand and aggregate while the cement remains in suspension, providing “gray water” for fresh batches. Users are able to gain higher truck utilization because cleanout is faster, and landfill costs are eliminated because cement paste is completely recycled. One-touch pushbutton operation processes each load to holding troughs to speed discharge to flow gates. Automatic metering of flushwater minimizes water usage.
