Vibrating aggregate, an apparatus for processing mineral material, and a method for moving a processing device of an apparatus for processing mineral material

A vibratory aggregate for an apparatus for processing mineral material, the vibratory aggregate comprising at least

• a frame,
• a shaft having an axial line and being arranged to rotate with respect to the frame,
• a first element coupled to the shaft in such a way that the mass centre of the element is not on the axial line, and arranged to move along a circular path,
• a second element coupled to the shaft and fitted to move along a linear path,
• wherein the phase of the movement of the first element in relation to the phase of the movement of the second element has been adjusted such that an elliptical movement of the vibratory aggregate is generated when the shaft is rotated.
