The natural sand has several disadvantages compared to artificial sand, which make artificial sand become the mainstay of stone-production in the field of construction. Pulled by the need of expanding domestic demand, infrastructure investment, such as roads, railways etc, is increasing. Such large engineering project needs lots of high quality sand. However，natural sand is non-renewable resources, with the large-scale exploitation, is increasingly drying up. In such a scenario, artificial sand is seen as a welcome alternative to natural sand. The application of artificial sand will effectively make great contribution to the development of our life. In the process of sand maker production, sand making and impact crusher g equipment is necessary.

The natural river sand is the product of sedimentation. Mica, coal, fossils and other organic impurities are present in the river sand. The increase of these impurities above certain percentage makes the sand useless for concrete work. For getting required fineness module the sand should be sieved. In routine average wastage of sieving are about 35% and extra Labor cost involved.
The natural sand available in the riverbed is very course and contains very much percentage of silt and clay which reduce the strength of the concrete and hold dampness. Fine particles below 600 microns must be up to at least 30% to 50% for good results. At present these particles are not present in river sand up to the required quantity.
