Abstract

Vibratory feeders are vastly used in a variety of applications such as minerals, petrochemical and food industries in order to transport the small parts such as granular materials. In this research, a flow of black pepper seeds in a vibratory feeder is modelled using discrete element method. The effects of tank vibration frequency, amplitude, and slope and the angle in which the motor orients on mass flow rate and motor required power are studied. The aim of this study is to reach an optimal design of vibratory feeder to obtain higher efficiency. The results of simulations are analyzed using analysis of variance. It is found that the most effective parameters on the mass flow rate and the required power are the motor orientation and the tank frequency, respectively. The best outcome corresponding to the maximum mass flow rate and the minimum required power is found to occur at the frequency of 15 Hz, amplitude of 15 mm, the tank slope of 5° and the motor angle of 45°.

黑胡椒种子包装中线性振动给料机设计参数的DEM研究

振动给料机广泛用于各种应用，如矿物，石油化工和食品工业，以输送小部件，如颗粒状材料。本文采用离散元法对黑胡椒种子在振动给料机中的流动过程进行了建模。研究了罐体振动频率、振幅、倾角和电机定向角度对质量流量和电机所需功率的影响。研究的目的是对振动给料机进行优化设计，以获得更高的给料效率。利用方差分析对模拟结果进行了分析。结果表明，对质量流量和所需功率影响最大的参数分别是电机方向和水箱频率。在频率为15 Hz，振幅为15 mm，水箱坡度为5°，电机角度为45°时，最佳结果对应于最大质量流量和最小所需功率。图示:四种参数下辣椒种子的质量流量及所需电机功率的变化

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.
