Insights into the Mechanochemical Synthesis of MOF-74 ...

Zinc oxide (0.181 g, 2.22 mmol) and H 4 DHTA (0.218 g, 1.15 mmol) were placed in a 25 mL stainless steel grinding jar, together with a single 7 g stainless steel grinding ball and 250 μL of DMF. The jar was sealed and milled at a rate of 30 Hz using a Retsch MM400 shaker-type mixer mill, and small portions of the powder (5–10 mg) were taken ...

How chalk is made - material, making, used, processing ...

Various crushers exist, but the principle is the same: all compress the stone with jaws or a cone, or shatter it through impact. Secondary crushing is accomplished by smaller crushers that work at higher speeds, producing pebbles which are then ground and pulverized. 3 The next phase, wet grinding, washes away impurities.
