  • Artificial aggregate made from waste stone sludge and

    01.11.2010· Natural aggregates are obtained by mining sand and stone, which are then crushed, washed and sorted. Waste silt is produced at typical aggregate washing plants at between 5 and 80 ton per hour depending on plant size and materials being processed. In general, 10–15% of the raw sand and stone will become waste silt.
