Abstract:
A vibration mixer comprising:an electronic controller; a motor attached to the electronic controller, said motor having a drive shaft assembly comprising a motor drive shaft and drive shaft housing; a mixing vessel; and an agitating assembly extending into the mixing vessel, said agitating assembly having vibrational motion and having a connection to the motor drive shaft, wherein said connection is adapted so that the vibrational motion of the agitating assembly expresses as reciprocating motion; wherein the electronic controller comprises an electronic control unit for generating control signals, whereby the control signals provide independent and simultaneous control over frequency and amplitude of vibrational motion of the agitating assembly; and a motor drive unit communicating with the electronic control unit and providing energy to power the motor in accordance with the control signals, wherein the control signals provide independent and simultaneous control over a continuous range of frequencies of the vibrational motion of the agitating assembly, wherein the frequency range has a minimum of about 0.01 Herz and a maximum of about 10 Hz, and wherein the control signals provide independent and simultaneous control over a continuous range of amplitudes of the vibrational motion of the agitating assembly, wherein the amplitude range has a minimum of about 1 micron and a maximum of greater than one meter.
