The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 1/8" to 1". Horizontal mills require much smaller media, as small as 0.05 mm to 2 mm. To read detailed specs and submit a quote, click here for our metallic media or here for our non-metallic media.
Jul 02, 2008· Estimated values of the specific selection function for each feed size interval are plotted versus particle size for different ball diameters in Fig. 1.Similar trends with respect to the variation of the selection function S i versus ball size were reported by (Austin et al., 1984).The optimum values obtained for 10, 20 and 30 mm ball diameter are about 0.45, 0.83 and 1.8 mm.
Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.
Jul 28, 2020· Ball mill installation is a must step before it is put into production, which will affect the subsequent use of the ball mill, and even affect the production volume, crushing rate, service life, etc., so the importance of ball mill installation is self-evident.. In addition, the choice of grinding medium is also crucial. In the grinding process, different grinding medium can be used for ...
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...
