But not all of gravels can be used for it, most of them are accumulated on river bed to effect river; some of gravels accumulated in shoreside to occupy the land space. It not be used for stone making companies, but it is a popular raw material for sand making, because sand making has a lower national standard than others. Normally to use abandoned materials, such as gravel、tailings、waste of construction materials、coal gangue and so on. The gravel is the best raw materials to make sand.
Gravel has hard texture and can be produced high stress sand. Therefore, it is a very popular raw material in . But it still need a right equipment which is impact sand making machine, using screens to sieve 5mm or 3mm product (there is a few dust in final production).
Making a have to pay attention to following points :
1. Size of gravel, which specification interval ratio is big? To decide using coarse crushing, or fine jaw crusher to crush.
2. How many percentage of mud content? It decides to use a sand washing machine or not.
3. If the gravel coming from river, have to think about the ratio of nature sand. Decide how to design the screen equipment, may need a drum sieve.
4. If the gravel is too hard, people can use to process, due to the high cost.
Anyway, people set up a production line depends different situations, but impact model sand making machine and YK/YA vibrating screen is must be used. Shanghai Jianye is a professional to produce sand making machine and to design a sand production line many years. More experiences can help customers to solve problems and to make the best design for different customers.
