## What are the limitations of a ball mill? Quora

Firstly, the movement plane of the medium in the ball mill is perpendicular to the gravitational field, and the medium movement must overcome the gravity to do work, so the grinding energy consumption is high Secondly, the consumption of steel bathe 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 This was explained by an analysis of the motion of the balls and the measurement of the contact force It was found that the grinding limit is greatly dependentThe Mechanism and Grinding Limit of Planetary Ball Millingt18/10/2004· Samples B, the cellulose and a sample of maleic acid were milled with a vibratory ball mill The peak areas below the spectrum within the limits were determined as shown in Fig 7C The band at 1110 cm −1 decreases in area during ball milling relative to that of the range from 1430 to 1270 cm −1 and it was therefore included in these investigations Using the area of the band at 670 cmEffects of shorttime vibratory ball milling on the shape
