### Effect of the Ball Milling Conditions, under Air, on the ...

The effect of wet milling on the hydriding properties of magnesium based mixture has been investigated. To prepare these mixtures, magnesium was ball milled with different weight percent of graphite (5, 10 and 25), at 300 rpm under air, for various duration using a ball miller apparatus Retsch S100 (R=12). Different solvents have been used such as benzene, heptane, styrene, DMSO.

### Grinding Media - Metallurgist & Mineral Processing Engineer

Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill.

### Effect of ball-milling time on mechanical properties of ...

In the preliminary stage of ball-milling some CNTs were distributed at the original powder boundaries. As the ball-milling time increased, the CNTs were gradually separated and dispersed into the Al powders (Fig. 3), and finally a uniform dispersion of the CNTs was achieved when ball-milled for an appropriate time (6 h).
