SAND MAKING APPARATUS, SAND MAKING METHOD, AND MADE SAND

摘要

a crusher 10; a first sorter 30 configured to sort crushed materials into coarse particles X, fine particles Y, and powders Z through air sorting and screening sorting; and a dust collector 80 configured to suck and collect the powders Z, wherein a second sorter configured to sort the powders Z into coarse powders Z1 and fine powders Z2 through the negative pressure of the dust collector 80 is disposed between the first sorter 30 and the dust collector 80, and a mixture of the fine particles Y and the coarse powders Z1 are used as made sand, thereby properties of concrete can be improved and excess by-product powders can be reduced.
