“…For a quick start, the flow rate appears exactly at the conveyor time of passage. It means that the solid in a pitch does not exchange with the next one, which is understandable as the powder mainly moves at the screw rotation speed [37,38]. Yet, for a quick stop, the flow rate decreases before the conveyor time of passage.…”

“…This approach is suitable for addressing idealized geometries and simplified systems. These analyses cannot provide insights into phenomena such as particle-particle interaction, particle-wall interaction, and inter-particle forces [16]. In practice, the design phase relies on standards [17,18], empirical estimates, experiential results, and results from partial experiments.…”

“…More suitable and increasingly used are discrete numerical methods, which enable the description and even optimization of highly complex geometries and conveyors. Although their mechanical design appears simple, the behaviour of granular solids and powders during transport is highly complex [16]. Screw conveyors have previously been examined and analyzed in the existing literature, with DEM analysis presented in reference [20].…”

Numerical simulations play a vital role in the modern engineering industry, especially when faced with interconnected challenges such as particle interactions and the structural integrity of conveyor systems. This article focuses on the handling of materials and emphasizes the importance of using parametric numerical analysis to improve efficiency, reduce wear, and enhance the structural integrity of horizontal screw conveyors. Through the utilization of the Design of Experiments, we systematically investigated critical parameters such as screw pitch, clearance, wear, rotational velocity, and additional structural factors. This examination was carried out within a well-defined parametric framework, utilizing a combination of software tools provided by the Ansys suite and Minitab. The findings demonstrate the effectiveness of the Design of Experiments analysis in achieving improved performance and provide valuable insights for engineers and researchers involved in the design of conveyor systems. Furthermore, this comprehensive approach clarifies how conveyor systems respond to changes in parameters and highlights the complex interaction between transported particles and the conveyor system. We present a detailed analysis that clarifies the complex relationships and dependencies among different parameters, providing engineers and researchers with valuable insights. By understanding the interactions of these factors, the methodology provides not only results but also a strategic framework for advancing conveyor system design and engineering practices.

The purpose of this paper is to solve the problem of low conveying efficiency and serious blade wear during vertical screw conveying of cohesive particles. Firstly, the reliability of DEM simulation was verified by comparing the simulated and theoretical values and the influence regularity of different design parameters (rotational speed, pitch, and clearance) on screw conveying characteristics were analyzed based on DEM. In addition, the effect of design parameters on the screw conveying characteristics is identified by ANOVA. Then, the multiobjective optimization model with the both of maximizing the average mass flow rate and minimizing the maximum wear depth of the blade was established using the polynomial fitting regression, which was solved by the non-dominated sorting genetic algorithm (NSGA-II). Finally, the comprehensive evaluation was used to determine the best design parameters. The above research results provide a certain reference for the study of cohesive particle’s vertical screw conveying characteristics and equipment optimization design.
