Effect of limestone grain size on the mobility of green ...

Nov 01, 2020· The maximum retention capacity was about 2–5 mg/g on the limestone grains and close to 19 g/kg on the calcareous soil. The clearly higher attachment of GT-nFe on the soil compared to the limestone grains is probably related to the presence of very fine particulates in the soil sample, i.e. 30% w/w between 2 and 63 μm, and 11% w/w below 2 μm.

Millstone - Wikipedia

Millstones or mill stones are stones used in gristmills, for grinding wheat or other grains.. Millstones come in pairs: a convex stationary base known as the bedstone and a concave runner stone that rotates. The movement of the runner on top of the bedstone creates a "scissoring" action that grinds grain trapped between the stones.
