WebA discrete element method (DEM), also called a distinct element method, is any of a family of numerical methods for computing the motion and effect of a large number of small particles. Though DEM is very closely related to molecular dynamics, the method is generally distinguished by its inclusion of rotational degrees-of-freedom as well as … WebDec 28, 2024 · Two types of sand production mechanisms are considered: production of coarse sands under mechanical failure and production of fine sands under hydro-dynamical erosion.

WebJan 1, 2024 · Cundall and Strack (1979)introduced the Discrete Element Method (DEM) which is a powerful tool to model sanding mechanism, where each sand particle is considered as an individual entity. This method can simulate the disaggregation of particles from the rock matrix, i.e. degradation and dissemination rock due to the erosion to small … WebThe model was then imported into the discrete element software EDEM, and a particle factory was established approaching the roof inside of the roller, and particle movement was simulated in the roller of the SAG mill. Different parameter combinations were used for simulation calculation in this experiment. nilc public benefits immigrants
