Abstract
To investigate the breakage characteristics of particle groups, the particle bed compression tests were conducted with feed groups. Three compression stages were determined based on the force–displacement curves of feed pellets with different aspect ratios. The occurrence of the stage ascent curve was explained by the microstructure of the feed pellet and the filling of pores in the particle bed. The influence of aspect ratio and moisture content on the mass-specific compressive energy was investigated, revealing that the energy increased with the increase of aspect ratio and water content. Additionally, the impact of these factors on the pulverization rate was assessed, demonstrating that the pulverization rate rises with the aspect ratio but diminishes with water content. The PSD (particle size distribution) of the feed pellet after compression was fitted with the Weibull function. The R2 values are higher than 0.97 and 0.93 for different aspect ratios and water content, respectively. Furthermore, new models were established to represent the PSD, taking aspect ratio and water content into consideration. The R2 values are higher than 0.95 and 0.96, respectively. These findings enhance the understanding of breakage characteristics of feed pellets under compression and provide a theoretical model for quality assessment of agricultural products.
期刊介绍：
Although many phenomena observed in granular materials are still not yet fully understood, important contributions have been made to further our understanding using modern tools from statistical mechanics, micro-mechanics, and computational science.
These modern tools apply to disordered systems, phase transitions, instabilities or intermittent behavior and the performance of discrete particle simulations.
>> Until now, however, many of these results were only to be found scattered throughout the literature. Physicists are often unaware of the theories and results published by engineers or other fields - and vice versa.
The journal Granular Matter thus serves as an interdisciplinary platform of communication among researchers of various disciplines who are involved in the basic research on granular media. It helps to establish a common language and gather articles under one single roof that up to now have been spread over many journals in a variety of fields. Notwithstanding, highly applied or technical work is beyond the scope of this journal.
