This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to .
الحصول على السعر· For the same amount of ball charge, the number of balls in the mill decreases as the ball size increases. Thus, the S values are lower for larger balls. However, larger balls are capable of breaking large particles; therefore, the size at which the S value becomes maximum, x m, increases as the ball size becomes larger.
