Özet
The mechanism that carries the powder or tiny granular particles with the rotational movement of the spiral shaft is called the screw conveyor. The working principle of screw conveyors is transporting dust particles due to rotating the screw shaft placed in a cylindrical pipe with engine power. The transport process transfers the powder particles to the conveyor from the feed pipe at the top of the mechanism to the wings (helix) of the helix shaft. In this study, a scaled prototype of the screw conveyor was produced. Different Bayburt stone (Tüfit) sizes were transported utilizing the prototype, and changes in the natural frequency of the screw conveyor were measured during particle transportation. The natural frequency value of the fine particles of Bayburt stone is determined as the lowest (15.67 Hz), and the natural frequency value is determined as high in the coarse particles (20.32 Hz). This is expected for this test, which is an example of forced vibration. The increase in the weight of the particles with increasing volumetric size also causes an increase in the external force values they create. The increase in mass value and the change in dynamic loads increased the natural frequency value for forced vibration. It has been observed that the natural frequency values increase in the range of 10-15 percent with the increase in particle sizes from fine to coarse. As a result, it has been determined that the size of the particles carried on the conveyor is important in determining the natural frequency of the system.
