Evaluation of particle size reduction and

2020-5-15  The specific surface area (SSA) of each size distribution was calculated by the equipment, as follows: SSA = 6/(ρ.D [3,2]), where D [3,2] is the surface weighted mean diameter and ρ is the specific mass of quartz (2.65 g/cm 3). The uncertainty associated with the determination of the characteristic diameters considering repeat grinding tests with 4 and 240 min was better than 10%.

2006-2-24  Silt composed predominately of quartz occurs abundantly in the sedimentary material found in deposits worldwide. Its origin is still the subject of many debates, but one acknowledged source is due to glacial grinding.
