RESEARCH ON MOVEMENT CHARACTERISTICS OF LARGE-VOLUME GLOBOIDS MATERIAL BASED ON PNEUMATIC CONVEYING TECHNOLOGY¹⁾

In order to obtain key parameters such as physical property parameters of large-volume materials, load comprehensive resistance coefficient and material shape coefficient, and to study the movement law of large-volume materials under different pneumatic conveying conditions, this research combines theoretical calculation, simulation analysis, and test experiment. Large-volume globoids materials movement characteristic parameter acquisition, test data correction and comparative analysis of movement data are investigated for different volumes, densities and conveying conditions. The data shows that under the given conveying conditions, the material movement characteristic parameters are distributed in a limited interval, and there is an obvious regularity between the physical properties of the material and the conveying movement. This research provides method and parameter guidance for the characteristic parameters used in the design and calculation of large-volume material pneumatic conveying engineering.
