Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

Atomic scale study of ball milled Ni-Fe 2 O 3 using ...

Mossbauer results indicate the dispersion of α-Fe 2 O 3 particles in Ni matrix in the as ball milled condition. Evolution of α-Fe 2 O 3 due to ball milling, reduction of the valence of associated Fe and possible interaction between the oxide particles with Ni in the matrix due to annealing treatments has been elucidated in the present study.

Entrapment of ball-milled biochar in Ca-alginate beads for ...

In this study, ball-milled biochar was entrapped and stabilized in calcium alginate to make it more stable and environmentally friendly. In addition, it is anticipated that the distribution of the ball-milled biochar in the composite would improve its sorption performance. Alginate is an anionic polysaccharide in the outer cell wall of brown algae.

Magnetic properties of ball-milled SrFe12O19 particles ...

Sep 15, 2015 · The room-temperature magnetic properties of ball-milled strontium hexaferrite particles consolidated by spark-plasma sintering are strongly influenced by the milling time. Scanning electron microscopy revealed the ball-milled SrFe 12 O 19 particles to have sizes varying over several hundred nanometers. X-Ray powder-diffraction studies performed ...
