To provide an apparatus and method for manufacturing sand, allowing effective use of surplus by-product fine powder generated in a crushing process, and the sand.

The apparatus for manufacturing the sand is provided with at least a crusher 10, a first sorting device 30 sorting crushed matter into coarse particles X, fine particles Y and fine powder Z by air sorting and screening sorting, and a dust collector 80 sucking fine dust Z for recovering. A second sorting device is provided between the first sorting device 30 and dust collector 80 for sorting fine powder Z into coarse fine powder Z1 and minute fine powder Z2 using negative pressure of the dust collector 80, and forming sand by a mixture of the fine particles Y with the coarse fine powder Z1 results in contribution to improvement in the concrete property and reduction of surplus by-product fine powder.
