Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them impact crushing can be of two variations: gravity and dynamic an example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an autogenous mill) dynamic impact could be described as material dropping
The critical speed is used for the determination of ball mill ideal operating speed but for comparison rod mills would operate between 50% to 95% of the critical speed the faster the mill speed the greater the wear on the rods and liners so the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the
