Pebbles, river pebbles, granite, limestone and other stones can be processed into sand by sand making machines and other machines. They can be used as machine-made sand instead of river sand in the construction field to make up for the current gap in river sand.
At present, the sand price market is still good. As long as the sand field is operated properly, it must be profitable. Many friends have turned their investment to this industry. As for the question of how much money can be made a year by opening the sand field, the production scale and operation are different, so it is impossible to give an accurate figure.
However, it is not possible for everyone to open a sand field. First of all, resources and funds are needed. It is not a small investment to often buy equipment on the sand field. At the same time, it is also necessary to comply with laws and regulations. It is necessary to apply for certificates in all aspects. Environmental impact assessment is a major problem reported by many customers, and the entry threshold is relatively high.
Generally, the processing of stones into sand requires feeder, crusher (also divided into coarse crushing and fine crushing), sand making machine, vibrating screen, sand washing machine, belt conveyor and other equipment. This is a relatively complete production line configuration for raw ore processing sand. If the raw material is already small stones, it can be beaten into sand directly through the sand making machine, and the previous crushing link can be omitted. The equipment can be increased or decreased according to the actual production situation.
At present, we have many stone processing sand sites all over the country. There are production videos for reference. We can also arrange to visit the production site nearby to see the equipment operation.
