    grinding media (steel balls) on power requirements and energy consumption of a ball mill. With constant mass of the steel balls (20, 30 and 40 kg), the agitator shaft speed was increased from 10 to 100% of the maximum speed, which corresponds to a speed of 50 rpm. The power consumption (W) was recorded upon which milling energy consumption

    Lesson 40: Conservation of Energy Total Mechanical Energy We sometimes call the total energy of an object (potential and kinetic) the total mechanical energy of an object. “Mechanical” energy doesn’t mean that it always has to involve machines. An apple falling off a cliff has gravitational potential and kinetic energy, so it therefore has mechanical energy.
