Mar 10 2020 It’s called a “ball mill” because it’s literally filled with balls Materials are added to the ball mill at which point the balls knock around inside the mill How a Ball Mill Works Ball mills work by using balls to grind materials Materials such as iron ore pain and ceramics are added to the ball mill Next the ball mill is
Validity of each theory within a certain particle size range This study illustrated that Kicks law was applicable in the crushing range (above 1 cm in diameter) Bond's theory was suited to the particle size ranges involved in conventional ball and rod mill grinding (5 to 250 mm) Rittinger's law showed _app1icability to the fine

Ball Size as Initial Charge Commercial ball sizes 10 – 150 mm Number size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge For the initial chargin of a mill Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed i e d †“V = 0 40
Large size mills with lifting liner bring grinding balls to higher heights and generate stronger impact force so the diameter of grinding balls can be smaller The ball diameter should be different according to the aging degree of the inner liner new liners bring grinding balls to higher height so the ball size can be smaller It can be seen
