The graphs show that for a courser feed a three ball mixture (50 + 20 + 10 mm) will provide the much required largest amount of size class of interest. For a finer feed a binary mixture i.e. 20 mm + 10 mm will satisfy the objective function which is to get more of the -150 + 75 μm size class material.

Answer (1 of 3): Ball mill grinding is one method of crushing ore to an appropriate size fraction. Specifically, ore is put into a large receptacle (a drum) and then it rotates slowly around. Inside the receptacle, there are balls, usually made of metal, that as the ore is rotated around the re...

Sometimes the ball mill is rubber lined mills which helps to reduce noise and wear at the same time. Ball mills can reduce particles to the nano sizes and as per need of an industry. For large production ball mix supervisors, mechanics and operators are hired to get a consistent product.

Ball milling of rye bran gave rise to similar results, with the A/X ratio of the extractable AX being considerably lower (0.51). Optimization of the ball mill treatment by varying the degree of filling of the milling jar permitted us to obtain equally high WE-AX levels (>70%) in wheat and rye bran within a 24 h ball-milling period.
