the energy efficiency of ball milling in comminution

according to this definition given that the energy utilization in a ball mill is between 121510 3 and 421510 3 m 2 /j and that the crack resistance value is between 30 and 60 j/m 2 the theoretical efficiency of the ball mill should be in the range of 1.512%.

stirred mills

stirred mills use less energy with grinding that results in decreased need for grinding media. the wasteful impact breakage of media to media or media to liner is eliminated which ensures fewer fractures and the media inside the mill can maintain its shape and usefulness longer. reduced carbon emissions
