blending and dispersing, amorphisation of materials and mechanical alloying 49, 51. As a construction, a ball milling device usually consists of a cylindrical vessel mounted on an appropriate basis at both ends which allows rotation of the vessel around the center axis. the mill is driven by a girth gear bolted to the shell of the
from one side. As the mill rotates at low speed the grinding media is ground into very fine particles due to the action of balls or rods on the grinding media. the ground products can be collected on other end. figure 1.1 shows the cut away section of a ball mill. figure 1.2 shows an industrial ball mill. the two types of tumbling mills
the critical speed of ball mill is given by, where radius of ball mill; radius of ball. for 1000 mm and mm, 30.7 rpm. but the mill is operated at a speed of rpm. therefore, the mill is operated at 100 1530.7 48.86 of critical speed.
