How to Process Sand-gravel Aggregate? |

Aggregate with particle size larger than 4.75 mm is called coarse aggregate, commonly known as the stone. Gravel and pebble are most common. Gravel is naturally formed or made by mechanical crushing and screening system and its particle size is greater than 4.75 mm, which are formed by natural weathering, water transport, sorting and accumulation.
