Different particle sizes: the particle size of stone powder is less than 0.075mm, while the particle size of machine-made sand is between 0.25 mm and 0.5 mm, which means that the particle size of machine-made sand is obviously larger than that of stone powder.

The particle shapes are different: the surface of stone powder is rough and the shape is sharp and uneven, while the machine-made sand is cubic particles with uniform particle size and regular shape.

Different uses: stone powder is often used to make plastics, coatings, paper, glass, ceramics and so on. Because of its fine particle size, machine-made sand is mainly used in construction and road engineering projects.
