Abstract Size reduction is the operation carried out for reducing the size of the bigger particle into a smaller one by external forces. This reduction in size is done by using ball mill. In the experiment, the stone weighs about 300g and mix with two handhelds of 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.
