Calcined ball milled sample at 450 C for 2 h revealed anatase TiO 2 phase structure with average particle size of 180 nm The results showed that the synergistic effect of Cu doping and ball milling before calcination considerably narrowed the band gap of the synthesized TiO 2 photocatalyst to 2 85 eV
12-8-2015High-density fine-grained Ni0 5Zn0 5Fe2O4 ferrite ceramics were synthesized by spark plasma sintering (SPS) in conjunction with high energy ball milling The precursor powders were milled for 20 h 40 h and 60 h respectively and the milled powders were all sintered for 5 min at 900C All the samples exhibit a single spinel phase
In fact the use of a single milling ball avoids impacts between balls which have a remarkable disordering effect on the ball dynamics whereas inelastic impact conditions permit the establishment of regular and periodic ball dynamics (Manai et al 2001 2004 Delogu et al 2004)
In addition the ball-milling effect on crosslinking performance of corn starch was also investigated It was observed that the milled starch granules lost surface smoothness at high milling loads (25 and 30 g) while some granules were squashed at low milling loads (15 and 20 g)
duced by highenergy ball milling which can also increase the homogeneity and reactivity of the mixture - [6] High-energy ball milling is a simple effective and productive way to produce various nano-crystal powders in high-energy planetary ball mills [7] High reactivity and small particle size can facilitate the production of high-
Ball milling as a mixing technique for UHMWPE based composites is not a new approach but yet the effect of time rotational speed loading of milling jar and type of ball mill has not been reported properly for UHMWPE Composites with 0 5 and 1 0 wt% UHMWPE/MWCNTs were manufactured with different rotational speed and mixing times
