Kumar, Sunil and Khan , Arbaz and Pandey, Ankit Kumar (2014) Dry grinding behaviour of Fe and SiO2 in specially designed Dual Drive Planetary Ball Mill. BTech thesis.
Mechanical alloying (MA) is a solid- state powder processing technique involving repeated welding, fracturing, and rewelding of powder particles in high energy ball mill. In the present investigation we have made an attempt to observe the grinding behavior of ductile iron (Fe) and brittle sand materials in dual drive planetary ball mill for 0h, 15 min, 1/2h, 1h, 1.5h & 2 h. The phase transformation occurring in the materials during milling were studied using X-Ray diffraction. Particle size analysis was carried out to study the size reduction as a function of milling time. It has been found that size reduction rate is very low in case of iron at the initial milling period due to ductile nature. In case of sand, the size reduction rate is very fast due to brittle nature.
