“…Thus, in the second part of the experiment, the 3^3 plan is implemented, where the angle of vibration direction is fixed at a certain position which has the greatest influence on the amplitude of movement. According to the studies carried out earlier, it is most appropriate to set the angle of oscillation direction 10 [11].…”

“…4 a), factors and their combination according to recommendations [8,9] are left in equation of mathematical model that will provide more flexible settings at transportation of granular material having different from ellipsoid shape. Based on the previously conducted research on the mathematical modeling of the vibrating conveying machine [11], fixing the eccentric mass value on the value that provides the maximum amplitude, we obtain a graphical representation of the response surface (Fig. 4, b).…”

“…In order to avoid displacement of grain to the periphery, concave surface with curvature radius of 0.065m was taken as conveying surface, providing uniform fine movement of grain. The design of the vibrating conveying machine provides for changing the angle of vibration direction in the range from 10 to 40 , with the possibility of changing the inclination angle of the conveyor chute in the range from 0 to 15 [11]. The setting of the vibrating conveyor machine was carried out as follows:…”

The present article represents the next stage in the cycle of work on the research of vibrating motion of grain material. This paper contains the experimental results of the operation of a vibrating conveying machine. The investigation was carried out in three stages. The purpose of the first full-factor experiment with four varying factors was to identify factors having the least impact on the time of movement of grain material. As a result, it was found that the angle of vibration direction that has an impact on the amplitude has almost no effect on the velocity of the grain material. In the second phase of experiment carried out with three varying factors at fixed angle of vibration direction, the equation of mathematical model of time of passage of the control area has been obtained. Moreover, on the basis of previous studies, the angle of vibration direction was fixed at the position which has the greatest influence on the vibration amplitude. The third stage of the experiment was to evaluate applicability of the obtained model equation to describe movement of other grain crops with ellipsoidal grain shape. Verification of the obtained model for adequacy using Fisher's criterion showed that with 95% probability the obtained equation can be used for estimation of movement of grain material having ellipsoidal shape on vibrating surface.

“…5) a negative phenomenon (Fig. 6) can be observed when tilting the vibrating surface, consisting of a displacement of the moving grain from the centre to the periphery of the conveying surface [11,12] It can clearly be seen that after hitting the vibrating inclined surface, the grain material gradually begins to shift towards the periphery, forming a gap in the centre of the vibrating conveyor. As a result of this phenomenon the efficiency of micronisation will be reduced.…”

The heating process of micronisation plays a paramount role in reducing the amount of anti-pittaels in the feed grain, changing the grain structure and increasing the availability of nutrients and improving their digestibility. The efficiency of heating generally depends on the design solutions used in the micronizing plant. This article gives an overview of some designs of installations for forage grain micronisation and presents the design of an installation for infrared micronisation of forage grain, which makes it possible to increase the efficiency of treatment, by reducing the burning of grain to the surface and ensuring uniformity of treatment.

Continuous conveying and mixing characteristics of high‐viscosity materials under acoustic vibration excitation

Investigating the conveying and mixing characteristics of high‐viscosity fluids in an inclined flow channel under the excitation of acoustic vibration using computational fluid dynamics methods. As the intensity of the acoustic vibration excitation increases, the free surface of the liquid transitions from generating Faraday waves to generating disordered jets. Continued increase in the amplitude leads to the liquid filling most of the vessel space, causing a blockage. However, slowly increasing the amplitude alleviates the blockage phenomenon. When high‐viscosity materials are subjected to high‐intensity acoustic vibration, the flow field is dominated by shear flow, which is accompanied by efficient stretching and folding. Changing the amplitude or frequency alone can cause blockage, and increasing the frequency of vibration excitation alone will not alleviate the blockage. Instead, increasing the amplitude can generate more mixing‐promoting reflux, effectively relieving blockage while maintaining stable conveying capacity.
