Oct 20, 2018 Ball mill is a grinder for reducing hard materials to powder. The grinding is carried out by the pounding and rolling of a charge of steel or ceramic balls carried within the cylinder. The cylinder rotates at a relatively slow speed, allowing the balls to cascade through the mill base, thus grinding or dispersing the materials.
Four experiments were performed with a laboratory scale overflow ball mill. Three were conducted to study the process and determine the parameters, and the last was for validation. The internal dimensions of the mill are 48.26 cm in length and 22.86 cm in diameter. The tests were performed at 70 of the critical speed and charged
