Dry and wet grinding behaviour of Fe and Sio2 in specially designed dual drive planetary ball mill

Abstract

In the project, an attempt has been made to observe the dry and wet grinding behavior of ductile material - iron (Fe) and brittle material - sand (SiO2) in dual drive planetary ball mill for 0h, 15min, 30min, 1h, 1/2h, and 2h through
mechanical alloying. 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 of particles as a function of milling time and it has been found that at the initial milling period size reduction is very low in case of iron (Fe) due to its ductile nature, and size reduction is very fast in case of sand (SiO2) due to its brittle nature. It was also found that less fine particles are formed during dry milling than wet milling due to formation of agglomerates.
