EXPERIMENT 3: SIZE REDUCTION USING BALL MILL Introduction A ball mill is a type of grinder used to grind and blend bulk material into QDs /nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell. The nanostructure size can be varied by varying the number and

Abstract Size reduction is the operation carried out for reducing the size of bigger particle into smaller one by external forces. This reducing in size is done by using ball mill. In the experiment, the stone are weight about 100g and mix with two handhelds of grinding ball into the ball mill. The speed control knob is adjusted each at 40 rpm and 90rpm.

Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
