Aug 01, 2018· Artificial sand making has a bright future in the construction industry. The demand for artificial sand is increasing rapidly. Here are the few reasons why artificial sand making has a good market opportunity in India. At present, the artificial sand is nearly 50% cheaper than river sand. The river sand is being sold at around Rs 1,300 a tonne.


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.


Jul 28, 2016· The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate …
