EDEM v2019 Released for Simulation

EDEM is the market-leader in Discrete Element Method (DEM) technology for bulk material simulation. EDEM simulation technology is used for 'virtual testing' of equipment that handles or processes bulk materials in the mining, equipment manufacturing and process industries.

The simulations based on the discrete element method (DEM) were carried out under similar conditions to examine the dynamics of the particles inside the mill, such as number of impacts, impact velocity and impact angle. The simulation results showed that most of the particles experienced multiple impacts before they were ejected from the mill.

In order to test the proposed tumbling mill model, DEM simulations of a 1.695m diameter pilot SAG mill using charge based on actual operation data were performed and analysed. Results from the DEM simulation and Drop Weight Tester breakage experiments were then used in the proposed tumbling mill model to predict the evolution of the product

DEM Simulation of Mill Charge in 3D via GPU Computing. four simulation tasks consisting of AG SAG and ball mills are reported. The simulation of AG and SAG mills are completed in less than 8 hours. The ball mill simulation with 1.25 million spheres is completed in 27 hours. In the near future these compute times can be halved with the advances

EDEM Components and Extended Capability The EDEM software platform, powered by state-of-the-art DEM technology, consists of three core components: EDEM Creator, EDEM Simulator, and EDEM Analyst.

Aug 01, 2006However, despite the usefulness, DEM simulation studies have not been applied widely to the high speed stirred mill system like IsaMill. This paper presents a numerical investigation of the flow of grinding media in a simplified IsaMill, aiming to examine the feasibility of using DEM simulation to predict particle flow in a high speed stirred mill.

DEM simulation shows a reasonably good correspondence to the pilot mill measurements. The difference is attributed to the fact that time-dependent behaviour of the rubber lifter is ignored, resulting in a too rapid relaxation of the lifter when the exerted force is released. Mill charge

3D Mining Simulation Ever since the introduction of discrete element method (DEM) for the simulation of grinding mills there has been a phenomenal growth in the variety of ways this technique is used in the mining industry. Since the late 90s two dimensional simulations have been the norm in the

The simulation of grinding process of an industrial scale ball mill was carried out using the discrete element method (DEM). Combining the information from DEM simulation and theoretical or empirical models, the related parameter values of mill performance are obtained, which have some reference value to the design, optimization and selection of ball mills.

Digital twin in the mining industry: a grinding mill case

In this webinar, presenters will describe advanced approaches that use coupled multiple DEM simulations (Discrete Element Method), IIoT, and predictive analytics. Simulation-driven digital twin concepts and algorithms are illustrated using a CADFEM CIS small-scale demo-mill facility that was created to demonstrate digital twin system

Sep 14, 2006This work has shown a method for simulating the motion of beads in a bead mill based on the discrete element method (DEM) under wet grinding of a gibbsite powder, in correlation with the experimental work. The beads' motion was simulated under a wet condition and compared with the real motion observed and recorded by a video camera.

Jan 01, 2016The discrete element method (DEM) also allows numerical simulation of the dynamic interaction of the mill charge media with the mill liners and lifters (Powell et al., 2011). The calculations are based on the fundamental laws of motion and can take into account of the geometry, dimensions and material property of each individual steel ball

As one of the machines widely used in mining, a semi-autogenous grinding (SAG) mill can significantly improve the roughing efficiency of rock. But the SAG mill still faces the obstacles of significant energy consumption and empirical operation parameters. In order to obtain the optimal operation parameters of a SAG mill, in this paper, the discrete element method (DEM) is used to simulate the
