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
Ball mill experiment initially the ground nut shell is crushed and then subjected to the ball mill for further size reduction the ball mill consists of a hollow cylindrical body of 268 cm diameter made up of stainless steel is filled with steel balls of 762 mm diameter the ball mill was rotated at 60 rpm critical speed 828
Ball mill in size reduction fob reference priceget latest price the mill with 30 cm in diameter and 30 cm in length and the test conditions are standardized with a maximum ball size of 40 mm and an ore top size of 335 mm with less than 300 balls it poses no challenge in running the simulations if only grinding media are included for such a small mill one could also include the ore or
