Concept Of Size Reduction Using Ball Mill 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 powder charge.

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 rpm.

Contaminationfree milling to reduce particle size is a considerable process challenge AVEKA Solution AVEKA responded to the customers needs by using a proprietary ball milling process that uses a specially cleaned and conditioned ball mill with a ceramic lining in conjunction with high purity high hardness ceramic media.
