Ball mill is the material being broken, and then smash the key equipment. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ore dressing, and black glass ceramic and other non-ferrous metal production industries, and other various ore grindability of materials for the dry and wet grinding.
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.
