For our experiments, we grind olivine using a planetary ball mill with an agate grinding bowl and agate grinding balls. We then expose the ground olivine to a dilute solution of the spin trapping compound 5, 5-Dimethyl-1-Pyrroline-N-Oxide, or DMPO. OH radical is produced as a by-product of reactions between pulverized olivine and water, but ...

This olivine sand is referred to as the original material. First several batches of original olivine material were milled. Four different mills were used, a laboratory planetary mill (P), a stirred media attritor (A), a Hicom mill (H) and a laboratory ball mill (B)". More details about the milling process and equipment are found in Haug [31].

12%Olivine lithium iron phosphate (LiFePO 4) is a promising cathode material for Li-ion battery. A temperature around 700 – 800 ℃ is generally required to prepare LiFePO 4 powder with good crystallinity. The LiFePO 4 materials are synthesized via a solid-state method by using a highenergy nano mill (HENM).

Grinding tests in pilot scale show that if the olivine additive is ground in closed circuit with a ball mill keeping good control over the top size, the olivine fineness can be appreciably decreased without disturbing balling. The olivine reactivity can be decreased by 40% compared to the reference olivine in the production plant.
