The features of the gravity method of beneficiation of heavy unclassified minerals require intense water currents at relatively large values of displacement, velocities and accelerations. This determines the use of a mechanical drive for jigging machines of the OMT type. ...

Using electronic modeling, the influence of the size of the gap between the piston and the walls of the machine on the oscillatory motion of the fluid was studied, and the maximum excess pressures in the chambers of the machine were determined at different values of the gap, as well as the velocities and accelerations of the piston. ...
