Abstract: After inserting the bulk solid in the box model simulates the movement kinetics of particle files and/or the individual particles. When passing bulk solid through box model is achieved by the total final kinetic state one of the following processes or the effects of partial folding of at least two of the following processes. One of the processes is the process s of creating the transition stress s state in the bulk solid by. Increasing the tilt angle of box model against the horizontal plane in any direction, at least one, and after the transition of stress state of continuous change the tilt angle in any direction as the positive and the negative effect of preselected angle. The second process is the process of putting the system in the transition state by setting the frequency of stress changes the tilt angle of the box model on the frequency of bulk solid flow. The third process is the process of at least one modification of bulk solid to be applied in modelling the links between the ideal bulk solid. In the event of two or more of the above processes take place at least two processes simultaneously and / or successively in any order, with values representing the overall picture of the possible simulation of kinetic states of individual particles and particle files and processes running in the box model converted into the model parameters of engineering works. The bulk solid can maintain the state of stress in transition periodic fluctuations tilting around the experimentally observed mean value in the experimentally observed limits. The first and / or second direction heeling angle model boxes against the horizontal plane may be in the course of at least one of the processes change continuously or intermittently. The bulk solid may consist of 1 to 1000 species of particles and may be at least part of at least one of the processes at the same time exposing the effects of vibration. 
     The device is made up of the box model (1) containing the model chamber (2) surrounded by walls (6), (16), (26) of box model (1), which is located in the bulk material (3). The device also includes pointing device (4) to tilt the box model (1) in any direction and/or rotation box model (1) randomly oriented around the axis in the positive in a negative sense. Box model (1) is adjusted to pointing device (1) or in force bond. Model chamber (2) may include a barrier (22) and bulk solid (3) may be model material, consisting of rounded particles. Box model (1) may be provided with at least one sensor (5) of the bulk solid (3) state, with the advantage of the pressure sensor and/or audio signal sensor and/or ultrasound sensor signal. At least part of the wall (6), (16), (26) box model (1) may be transparent and equipment may include observation unit (7), with the advantage of camcorder. Pointing device (4) may contain at least one pin (8), (18) and/or at least one shaft (9), (19) for the rotation or tilt box model around any axis oriented and/or at least one joint for tilt and/or turn the box model (1) randomly oriented around the axis and/or at least one joint (10) for tilt and / or turn the box model (1) in any direction and any angle. The box model (1) and/or pointing device (4) can be fitted with at least one vibrator (11), (21).
