In the field of mining, it is widely used in the pre-mill process, which can produce a large amount of pulverized ore and reduce the high-cost milling load.

In addition to this categorization, qualified aggregates will be divided more carefully in construction sand so that these construction sands can be used in different fields:

1. Coarse sand. Mainly used for, beams, slabs, columns, foundations, flooring concrete.

2. Medium sand. Mainly used for plastering of internal and external walls, ceilings and leveling layer of floors (roofs), also used for, concrete for beams, slabs, columns and foundations. Concrete mixing, masonry, plastering mortar
