How does coarse-grained granite compare to beach sand? ‘Sand’ is a size description. It really says NOTHING about the composition of the sand. A sand can be quartz, or calcite, or feldspar, or shell fragments, or a mix of those, or glass particles – as long as the particles are ‘sand sized’, then you have ‘sand’.
Granite is – by definition – a coarse-grained igneous rock (I will grant that there are ‘finer’ and ‘coarser’ grained granites). Granite has a specific range of mineral composition: it consists mostly of alkalic feldspar, with biotite or perhaps some hornblende, and quartz with variable trace minerals.
If you disaggregate a granite (that is, separate all the minerals from each other) then sometimes you have loose material which is sand-SIZE, but usually the individual minerals in the granite are granule size (the next size larger than sand) as you’d expect from a ‘GRAN-ite’ which is a ‘GRANular’ rock (-ite is the suffix for rock).
V5X impact crusher can crushing the granite into sand and gravel, the device can be used in highways, railways, bridges, mineral milling and other fields. Machine made sand can be used instead of natural sand, which is used for general concrete structure. Granite sand making machine feeding processing strength, feeding intensity up to two hundred and fifty tons per hour, out of the material size can be fine to 4.66mm. Crushing efficiency is also higher.
