Characteristics of sand and criteria for its comminution

Initially, a Mortar Grinder was used for this task: 20 g quartz sand is ground analytically fine with the Mortar Grinder PULVERISETTE 2 with agate bowl in 30 minutes. But in only 5 minutes, 100 g of quartz sand is ground to a comparable analytical fineness by using the Planetary Mono Mill PULVERISETTE 6 classic line,with a 250 ml agate grinding bowl and 15 agate balls with 20 mm diameter.

Effects of concrete grinding residue (CGR) on selected

2019. 12. 10. The physicochemical properties of the CGR are given in Table 1. The specific gravity (G s) of the CGR, determined by a water pycnometer ( ASTM D 854-14, 2014 ), was 2.4. The mixed slurry had a solid content of 44%, and its gravel sand, silt and clay mass fractions were 0.6%, 46.3%, 38.9% and 14.2%, respectively.
