What is the sand production equipment-river pebbles sand making machine?

With the development of infrastructure, urbanization construction, the repair of roads and bridges, natural sand and gravel gradually reduced. It has been unable to meet the needs of infrastructure. Natural resource cycle is relatively long, so research and development the resource to replace natural sand is being a project by the construction industry.

At present, after investigation, in addition to natural sand, there are many ore can be processed to building sand. General materials are river gravel, pebbles, basalt, granite, limestone, slag and so on. Due to river pebble has compression, wear resistance, corrosion resistance, is a most suitable green building sand.
