An Interview On Cobble Or River Sand For Sand Making Production Line Cobble For Sand Making Production Line
    • Host: Cobble (River gravel) is a pure natural stone. At present, most raw material of the artificial sand is the cobble. With the rapid development of construction in China, the artificial sand demand is more and more increasing. Then, there is a large demand for the cobble. Today, we invite the expert—Mr. Wang to introduce the cobble and its sand making production line. Welcome Mr. Wang.
    • Mr. Crusher: Hello, everyone. I'm very excited. I'm glad to take part in today's interview. Hope it will helpful for everyone.
    • Host: Mr. Crusher, as far as I know, cobble is the most popular material for artificial sand. So what does it have the advantages?
    • Mr. Crusher: Cobble resource is rich. It is a pure natural stone. Its exploitation cost is low. And it has less impurity. In addition, cobble's particle type is good. It is strong and durable.
    • Host: So, why doesn't use the sea sand or the mountain sand? They are both the natural stone.
    • Mr. Crusher: They are not the most suitable choice, compared with the river sand. The mountain sand's surface is rough. There are a lot of edges and corners. In addition, it has a large amount of mud and other impurities. For the sea sand, it has also many impurities. It has the corrosiveness. Its desalination cost is high. Sea sand is usually used for land reclamation, industrial, iron-making etc.
    • Host: Oh. So the cobble is the best choice for making artificial sand. Them, can you tell the cobble for sand making production line for us?
    • Mr. Crusher: Of course. In the sand making line, jaw crusher is usually used as the primary crushing machine. Cone crusher or impact crusher is used as the second crushing machine. Through the first and second crushing, cobble is transported into the vibrating screen for screening. At last, we can get the finished product with suitable size. In addition, it also needs vibrating feeder, belt conveyor, and other auxiliary machineries. This is the simple process of sand making line.
    • Host: Very great! Through this interview, we know more about the cobble used for sand making production line. Thank you, Mr. Crusher!
    • Mr. Crusher: You are welcome! I'm glad to take part in today's interview.
