Grinding mechanism of centrifugal mills — a simulation
Abstract This paper presents a model developed to simulate the family of ball mills i.e. the tumbling mills centrifugal mills vibration mills and planetary mills and its application especially to centrifugal mills in brief comparison with vibration mills. The model is based on the discrete element method (DEM) and is capable of describing the motion of balls and estimating the energy

The Mechanism and Grinding Limit of Planetary Ball Milling
· Based on this result it is predicted that the grinding mechanism in the planetary ball mill consists of compressive abrasive and shear stress of the balls which is believed to be effective in producing very fine particles. About thirty percent of ball filling of the mill was found to be the optimum.

Different reaction mechanisms during mechanical alloying
Abstract. Two different reaction mechanisms for Ti 50 C 50 and Ti 33 B 67 have been observed respectively during milling in a planetary ball mill. It is shown that a gradual reaction occurred during milling Ti 50 C 50 while a self-sustained reaction was obtained during milling Ti 33 B 67 under the same milling condition. Compared with the results of milling Ti 50 C 50 in a spex mill the
