Fig. 1(c) is a picture taken simultaneously under the same operating conditions except that the exposure time of the camera was set at 2 s and the flashing rate of the strobe 60 fps. In other words, there are 120 frames during one and half revolution of the mill. It can be seen from Fig. 1(b) and (c) that: (1) balls in the tumbling mill are moving in layers (at least four …

An expression for the critical speed of a mill will now be derived. By reference to Fig. 2.6, it is easily seen that if the trajectory is not to fall inside the shell, the radius of curvature of the path, e, must be greater than R, that is than that of the mill shell. Furthermore, this must be true for from wherever the trajectory might start.

Utilitarianism is a branch of moral philosophy according to which the moral worth of an action is determined solely by its usefulness in maximising some measure of "utility" summed over all sentient beings. "Utility" can mean different things such as pleasure, satisfaction of preferences or even knowledge, but the basic idea is that, ultimately, there…

When the ball mill rotates at the critical speed the theoretical trajectory of the charge is such that it would fall outside the shell as centrifuging occur at this stage and the medium is carried around in a fixed position against the shell. The formula to calculate critical speed is given below. N c = 42.305 /sqt(D-d) N c = critical speed of ...
