Natural sand resources can not meet the need and therefore the importance of the manufactured sand is growing.

For the choice of cyclic manner, used sand mining equipment should adopt open circuit approach.

For the choice of dry and wet production, it need to consider from various aspects.

When the scale of the system is small, dry process production can be used; large-scale artificial aggregate system should adopt wet process production.

Dry production line will not need investment of water, which reduces capital investment to some extent.

Dry production line does not need water for cleaning and stone powder that is generated in the production process can be reasonably used, which in a way saves the water and mineral resources and is ore environmentally friendly than the wet production line.
