Grinding Sand to Determine its Mineral Composition

100 g sand ground in 5 minutes in the PULVERISETTE 6, 250 ml agate grinding bowls, 20 mm grinding balls. The comminution of sand is unproblematic because it is brittle. However, due to its composition, sand may have varying degrees of abrasiveness. Typically, a mill with impact forces is chosen to minimize this influence.
