effects of increased tonnage to a ball mill
Wrecking Ball Physics Experiment and lesson
If we look at a wrecking ball it is basically a pendulum.A pendulum is a weight hung from a pivot point and allowed to swing freely until friction between the weight and the air slows and stops the swinging of the pendulum and it eventually comes to a stop Pendulums work because of the energy involved in their systems When the pendulum weight is raised it contains gravitational potential
