Stone covers the surface of our earth and makes up the earth’s crust. The outer layer of crust is lithosphere and this layer is made up of stones.
There are three kinds of common stones: stones used in road building, aggregate of bridge building and stones used in architecture and sculpture design.

We know there are thousands kinds of stones in the world. But what we say today are those stones or materials that are similar to stones which can be used in building or carving. Stones refer to those stone which can be used as industry materials, such as iron ore, nonferrous metal ore, granite, limestone, quartzite, sandstone, pebble, etc.
There are three kinds of common stones: stones used in road building, aggregate of bridge building and stones used in architecture and sculpture design. Stones used in road building should be tidy and of high quality. Aggregate of bridge building should be flag, rock block, quadrel, rubble ashlars and tapered rocks. Stones used in architecture and sculpture design are also the stone we talked here.
Stone crushing process
You see from the introduction of stone above, stone can be used just after being processed into small pieces. And stone crushing plant is specially designed for this process. Firstly, stones are explored from hills and get transmitted to the vibrating feeder. Then vibrating feeder pours them into primary crusher. Then products of primary crusher get crushed by secondary crusher. Secondary crusher crushes stones into smaller size and usually they can get used. But more often the products of secondary crusher get screened by vibrating screen and whose can fit the requirement will leave this process and become the final product and the others will go back to secondary crusher or even primary crusher to get crushed. Finally, stones all become the right products we need. Tertiary crusher is usually used in special crushing process. Tertiary crusher will process stones into much smaller size than secondary crusher.
Stone crushing plant
Stone crushing plant including three kinds of stone crushers: primary crusher, secondary crusher and tertiary crusher. What’s more, vibrating feeder, vibrating screen and belt conveyor is necessary in crushing process and are links of stone crushing plants. NFLG supply the best stone crushing plant to our customers.
