Boosting Mine Chute Design - Improve Chute Design and Reduce Costs with Altair EDEM

Wood is responsible for assessing material handling transfer chutes for crushed ore. The large number of transfer chutes must be optimized to enable the transfer of bulk material from one conveyor belt to another, and to adequately direct the flow of material. Some of the most common issues with material transfer designs include plugging, segregation, and abrasion wear. In an effort to reduce operating maintenance costs, Wood employed the use of Altair EDEM, a discrete element modeling (DEM) solution, to visualize the flow of material and analyze forces and moments acting on different parts of the transfer chute. As a result, Wood reduced the weight of this transfer chute by approximately 10%, adding $20,000 in NPV to the project.

ATCx DEM 2020 - Virtual Process Optimization for Rotary Drum Coaters

Coating of particulate solids by a thin film layer is of interest in many industrial applications such as seed and tablet coating. In seed processing, seeds are commonly coated with a protective coating layer consisting of fertilizers and crop protection products. Rotary drum batch coaters are typically used for this purpose.

In the present study, Discrete Element Method (DEM) simulations are used to analyze the seed coating process, using corn seed as model material. The coating uniformity of the seeds is predicted by implementing two coating models. The distribution of mass of sprayed spheres on the corn seeds, their residence time in the coating zone and the coefficient of variation of coating mass and residence time of the seeds are evaluated for a range of process conditions, such as spinning disk rotational speed, droplet size, and baffle arrangement and designs.

ATCx DEM 2020 - The need of proper modeling of traction control system in mobility simulations on soft soil

When building simulation models of military vehicles for mobility analysis over deformable terrain, the powertrain details are often ignored. This is of particular interest for electric and hybrid-electric vehicles where the maximum torque is produced at low speeds. It is easy to end up with the drive wheels spinning and reducing traction and eventually the vehicle digging itself down in the soil.

The presentation discusses the reason why simplified terramechanics models (ST) such as the Bekker-Wong models are not suitable for dynamic traction control studies and shows how Altair EDEM's complex terramechanics models (CT) can be co-simulated with multi-body dynamics software Adams using the ASCI interface.

The presentation focuses around an 8x8 transport vehicle with and without TCS. To model the traction control system a PD controller is used to limit the slip velocity at low speed and wheel slip at higher velocity. A soil model has been correlated to the Pratt & Miller sandbox and a 35% hill climb was used to tune the TCS parameters in the co-simulation.

ATCx DEM 2020 - DEM modeling of particulate processes – from conceptualization to industrial application

The Discrete Element Method (DEM) is increasingly being used to simulate powders and particulates that are common in many industrial and natural processes. Since DEM computes at individual particle level, it has the potential to capture the underlying particle phenomena of a problem such as friction, cohesion or breakage, which in turn informs the bulk industrial process of interest. Using a few examples, this presentation will discuss model conceptualization of problems in developing effective solutions to address challenging industrial problems.

ATCx DEM 2020 - Optimizing pneumatic conveying of cohesive dairy powders using EDEM–CFD coupling

Pneumatic conveying pipelines undergo series of direction changes due to space restrictions, site location, or position of receiving silos and hoppers. When dairy powder and air flows around pipe bends or experiences any change in flow direction during pneumatic conveying, the particles form a rope-like structure due to inertial, gravitational and centrifugal effects. The formation of such particle ropes can lead to particle stratification, re-agglomeration, deposition, and pipe blockages especially when handling cohesive powders.

This research focuses on the design and optimization of novel flow-aided pipe bends that prevents powder deposition, pipe clogging, and improves throughput. Several conceptual designs of such flow-aids are investigated for various bend orientation by coupling Altair EDEM with Computational Fluid Dynamics (CFD) supported with targeted experimentation. The optimum flow-aided design integrated into a pilot-scale conveying test rig results in higher rope dispersion after the than similar test rig with conventional bends.

ATCx DEM 2020 - A model for simulating particle breakage with high fidelity in EDEM

Desired or not, particle breakage can occur when dealing with particulate materials in industry. For cases in which breakage severely influences the flow of the material, the only viable option is to describe it within the DEM environment. Several powerful approaches have been proposed over the years, but only very few are suitable to be used in large-scale simulations.

The presentation shows one such model that has been implemented in Altair EDEM to describe body breakage of brittle materials. It is based on a novel stochastic particle replacement approach involving spheres. It accounts for variability and size-dependence of fracture energies, besides weakening when particles do not break and fragment size distribution dependent on stressing energy. Results from model verification and validation in EDEM are presented, which demonstrate its high fidelity, besides examples of application to predict breakage in selected crushers.

ATCx DEM 2020 - Wear simulation using automated geometric deformation with the discrete element method

Tools used in soil cultivation are subject to heavy wear. Simulation methods, such as the Discrete Element Method (DEM), show a good suitability to analyze these processes. In materials science, many investigations of wear are based on the scratch test, in which a diamond tip is moved along a material surface and the volume removed provides information about the abrasion behavior. With the DEM it is possible to simulate this scratch test virtually.

During the simulation of the stress, no geometric deformation according to the expected wear takes place so far. For this purpose, a program has been developed which changes the geometry of the tool to be examined at defined intervals as a CAD model and returns it to the simulation. The interaction is automated, so that no manual adjustments are necessary and the wear process can be displayed in any detail.
