在干颗粒涂覆中，利用机械力将微小的亚微米客体颗粒涂覆到较大的微米尺寸的主体颗粒上。本文使用离散元法 (DEM) 对几种干颗粒涂层系统（即 Mechanofusion 系统、Hybridizer 系统和磁辅助冲击涂层系统）进行了建模和研究。结果包括运动学变量的分析，例如平移、旋转动能，以及不同干颗粒涂层系统的碰撞强度和频率的计算。还研究了这些系统在不同操作参数下的操作，这些结果说明了 DEM 在理解干颗粒涂层系统动力学方面的重要性。还讨论了需要进一步研究的领域。
In dry particle coating, tiny sub-micron guest particles are coated onto larger micron-sized host particles by using mechanical forces. In this paper several dry particle coating systems, i.e. the Mechanofusion system, the Hybridizer system and the magnetically assisted impaction coating system, have been modeled and studied using the discrete element method (DEM). The results include an analysis of kinematic variables such as translational, rotational kinetic energies, as well as the computation of collision strength and frequency for the different dry particle coating systems. The operation of these systems under different operating parameters have also been studied and these results illustrate the importance of DEM in terms of understanding the dynamics of dry particle coating systems. Areas that require further research are also discussed.
