Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal C3 is the correction factor for mill diameter and is given as; 3 = (3) However, it is important to note that C3 = vessel used in producing the ball mill was got from a
A ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. The materials are ground by moving the container. Because the structure of ball mills is simple and it is easy to operate, and so they are widely used. However, designing these devices and selecting conditions depend in many ways on
