Preparation of Fe(III)MOFs by microwaveassisted ball for ...

FeMOFs were prepared via microwaveassisted ball milling. Fe 2 (SO4) 3 and Trimesic acid were reacted in an aqueous solution in only a few minutes and no change of the solution color would occur after a reaction time of 30 min, illustrating that the reaction was finished and the Fe(III)MOFs were produced. Most MOFs are synthesized by a solvothermal method.

Cement grinding Vertical roller mills versus ball mills

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...
