Ball-milling-induced crystallization and ball-milling ...

2007-4-1  At a low ball milling rate, both the particle size and coercivity decrease slowly and monotonically with increasing milling time. Even after 48 h milling, both powders with an average particle size of about 2 {mu}m still retain about 40%-50% of their initial coercivity.

Physicochemical properties of rice bran after ball milling ...

2021-7-26  The particle size of rice bran is a critical characteristic for the processing and eating quality of rice bran food. After hammer milling and ball milling, the physicochemical properties of rice bran with different particle size (203.33, 101.33, 71.10, 41.80, and 18.90 µm) were investigated, including hydration properties, antioxidant properties, nutritional properties, and microstructure ...

Ball Mill - an overview ScienceDirect Topics

2021-8-2  Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Amorphous and nanocrystalline Fe–Ti prepared by ball

Nanocrystalline FeTi has been prepared in two ways: by ball milling the intermetallic compound and mechanically alloying a mixture of the elemental powders. The materials obtained in each case are identical. The reaction proceeds via the formation of interfacial β–Ti(Fe) which then grows to include all of the material present.

Preparation of graphene by exfoliation of graphite using ...

Wet ball milling was used to exfoliate graphite platelets into graphenes in a liquid medium. Multi-layered graphite nanosheets with a thickness of 30 to 80 nm were dispersed into N, N- dimethylformamide ( DMF) and exfoliated by shear-force-dominated ball milling carried out in a planetary mill. After high-speed centrifugation, irregular shaped ...

Anisotropic Sm-(Co,Fe) nanoparticles by surfactant ...

2009-2-12  Magnetically hard Sm2(Co0.8Fe0.2)17 and SmCo5 nanoparticles have been produced by using surfactant-assisted low- and high-energy ball milling techniques. Surfactants prevent the rewelding of the crashed particles during the milling process. Heptane was used as the milling medium and oleic acid as the surfactant. High-energy ball milling experiments took place in a milling vial with carbon ...
