Abstract:
Excessive vibration in industrial mixers such as flotation cells and draft tube mixers is attenuated by connecting a vibration dampening device to a rotor or impeller which is disposed in a mixing tank for pumping a nonhomogeneous fluidic material placed in the tank. In a draft tube mixer, where the rotor is connected to a drive shaft in turn connected to a motor for rotating the rotor, the vibration dampening device is connected to the shaft on a side of the rotor opposite the motor. In a froth flotation cell, if the rotor is hollow, the vibration dampening device is disposed inside a pipe in turn mounted inside the rotor along an axis thereof. The vibration dampening device takes the form of a tuned mass dampener tuned to a resonance frequency of the particular mixing apparatus.
