6) Vibrating screen is a vibrating system. Thus, screen deck mass plus material mass on deck is total mass which is resting on springs. This is vibrated by exciting force. Mass, spring stiffness, damping factor (hysteresis losses) and exciting force are complementary; and together will create desired vibration.
