Bulk Processing Equipment: Sand and Gravel
Ideal conditions for mining are when the ground is moist or wet as it helps to avoid dust pollution in or around the mining site. The other method by which sand and gravel are mined is called dredging.

Once mined, the materials are transported ...More
Sand mining - Wikipedia
Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete. It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface. Sand can replace eroded coastline. Some uses require higher purity than others; for example sand used in concrete must be free of seashell fragments.More

What Are The Negative Effects Of Sand Mining? -
13/11/2018 Unregulated mining of large volumes of sand along beaches leads to their erosion. Sea beaches are usually formed by the balanced action of depositional and erosional forces. Although this balance is naturally maintained, humans interfere causes excessive erosion and thus the retreat of beaches. By removing too much sediment from rivers, sand mining also leads to the erosion andMore
