In terms of particle size as used by geologists, sand particles range in diameter from 0.0625 mm (or 1⁄16 mm) to 2 mm. An individual particle in this range size is termed a sand grain. Sand grains are between gravel (with particles ranging from 2 mm up to 64 mm) and soft sand (particles smaller than 0.0625 mm down to 0.004 mm).
Sand crushing machine is the equipment which makes soft sand artificially. It can be used together with impact crusher or cone crusher according to the material condition and production requirement. Sand making impact crusher (VSI crusher) is applicable for various coarse, medium and fine materials such as all kinds of rocks, refractory materials, cement clinker, quartzite, iron ore, concrete aggregate. It is the best mechanical equipment for aggregate for high-class highway pavement and construction of hydropower facilities.
