Nov 01, 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.
