EFFECT OF HIGH ENERGY BALL MILLING GRINDING ON

by processing in a high-energy SPEX 8000M mill using a hardened vial with steel balls keeping a ball to sample ratio of 51. Milling intensities were 0, 1, 2, 4 and 8h. The composite preparation was done from mixtures of milled Gr with Al powder (1% Gr in wt.) for 1h. For mechanical characterization, the milled Milling reduced particle size, enhanced amorphism, and increased the release of structural cations from the rocks, with the effects due to dry milling being greater than for wet milling. The optimum milling times which produced maximum amounts of exchangeable cations (Na, K, Ca, and Mg) were 30 -
