Aug 02, 2013· In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize โjust in caseโ. Well, this safety factor can cost you much in recovery and/or mill liner wear and

Design Method of Ball Mill by Discrete Element Method collected. The diameter of the gibbsite powder was measured using a Master Sizer 2000 (Sysmex Corpora-tion). Details of the experimental conditions are given in Table 2. Results and Discussion 1. Effects of Fins on Ball Motion in the Mill To predict ball mill grinding behavior using the dis-

Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal to1.20. C3 is the correction factor for mill diameter and is given as; ๐ถ๐ถ3 = 2.44 ๐ท๐ท 0.2 (3) However, it is important to note that C3 =0.914 vessel used in producing the ball mill was got from a

The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

balls which exist in mill, ๐ด๐: each ball abrasion (g), ๐ดt: total ball abrasion in the mill (g), ๐ฃb: each ball volume (m3), ๐b: supposed ball filling percentage, A r: ball abrasion rate in the mill. If above calculation were done again for ๐b = 2%, total ball abrasion will get 60.96, finally.

Ball mills Ball mills are used for dry and wet grinding of different materials such as cement materials, cement, lime, and ceramic materials. PSP Engineering has continuously re๏ฌ ned the design of its ball mills. Horizontal ball mills have become a reliable part of grinding plants Main characteristics of ball mills seated on shoe-type bearings
