Featured are dynamic modes of material that is being transported. Presented is the optimum material handling, and most rational mode. Introducing the empirical dependence transport speed as a function of angle bending conveyor, amplitude of oscillation of the transport container, the oscillation frequency excitation angle at which operates the actuating force and the coefficient mode of operation of the conveyor. Featured are some of the drive vibratory conveyors, and especially the operation of electromagnetic vibratory conveyor. Key words: Vibratory conveyor drive, Kinematic and dynamic modes, Electromagnetic vibratory conveyor INTRODUCTION Vibratory movement is one of the most efficient methods of conveyance of granular and particulate materials. Vibratory conveyers (VC) are widely applied in many technological processes involving gravimetric transport, processing, and dosing of granular materials. From the macroscopic point of view, the process of vibratory conveyance is based on recurrent micro-displacements of particles of the material being conveyed [1-11]. Basic Types of Operations in VC  conveying along to the horizontal surface  conveying along to the lightly inclined surface  conveying along to the spiral elevator  vibratory dosing; loading and (or) discharging  vibratory finishing; pulverization and separation  vibratory compaction  vibratory rapping (electrostatic precipitators) VIBRATORY CONVEYANCE KINEMATICS Simplification of the kinematics of a typical vibratory conveyor is shown in Figure 1. Basic kinematic size vibratory conveyors are presented in Figure 1(a) are: displacement, - l X , velocity- L v and acceleration transport containers- L a ; trajectories of particles of bulk material is shown curve - p X . The fact of the support element on one imaginary particle bulk medium to be transported, is shown in Figure 1 (b). It is assumed that during the cycle of the vibrating conveyor oscillates between the position of the court with the labeled (M) and (P), so that the value of the vibration width m X  2 . The increase in the speed of oscillation is between the (M) and (N), so that the vibrating receptacle is speeding up, while decreasing the speed of oscillation between the (N) and (P), when the vibratory bowl slows down. For travel transmission containers to above, between the position (M) and (N), the particle is in contact with the surface transportation containers. In the position (N) particle velocity becomes greater than the speed of transportation containers and leaving its surface and keeps moving free-fall trajectory by (P) - (Q). During this time vibrating the container was moved to the lowermost very position, so that the particles fall on its surface, and the next cycle begins again the particles move from point (Q).  Conveying process is based on a sequential throw movement of particles 
