## SYNTHESIS OF IRON OXIDE PIGMENT BY PLANETARY MILLING

Grinding mills include oscillating and vibration mill, attrition jet, planetary mills, all of which are known as high energy mills [4]. Among all, planetary milling is the most simple and widely used plastic deformation method through which one can achieve extreme refinement in the structure of materials in bulk amount.Size reduction with Planetary Ball Mills,Planetary Ball Mill. The PM 100 CM operates with a speed ratio of 1:-1 (centrifugal mode). The centrifugal forces pro-duced by the rotation movement the sample and the grinding balls against the inner wall of the grinding jar, where size reduction takes place primarily by pressure and friction.

## Development of iron-iron carbide composite by planetary

MTech thesis. PDF 1357Kb: Abstract. Fe-6.67 wt. %C and Fe-1 wt. %C powders were milled in a dual drive planetary mill for 40 h. It has been found that there is a formation of Fe3C and other iron carbides after 40 h of milling. However, the formation of iron carbide is more in the case of Fe-6.67 wt. %C as compared to Fe-1 wt. %C.SYNTHESIS AND CHARACTERIZATION OF ENERGY ,VIA HIGH ENERGY PLANETARY BALL MILL ING Academic Session : 2014/2015 I declare that the thesis is classified as : I acknowledge that Universiti Malaysia Pahang reserve the right as follows : 1.
