Using Altair EDEM in Mining and Metals

Watch examples of applications of EDEM in the mining, mineral processing and steelmaking industries. EDEM software, powered by the Discrete Element Method (DEM), enables engineers to predict the flow behavior of rocks, ores and coal, ores through each segment of their equipment and operation. It is used to evaluate and verify the design of transfer chutes and to optimize comminution equipment such as crushers, ball mills, as well as vibrating screens.

Blast Furnace Charging using Altair EDEM

Bulk and granular materials such as iron ore, coal, pellets and sinter are at the core of the iron & steelmaking process. Efficient handling and processing of those materials are critical to achieving efficiency, however, there are many challenges that engineers face for the different stages of the ironmaking process. In addition, steelmaking companies are under immense pressure to improve energy efficiency and reduce carbon emissions whilst maintaining steel quality.

One of the main processes that are subject to this improvement on emissions and efficiency, whilst maintaining steel quality, are blast furnaces. The charging of the blast furnace which has a significant impact on its efficiency, energy usage and product quality can be simulated and optimized with Altair® EDEM™ simulation software. Using EDEM, you can model large systems like the charging of a blast furnace, providing highly relevant information on the efficiency of the process from a virtual model. This allows you to optimize the burden distribution and predict any segregation or wear on the distributor chute and staves.

Use Cases

EDEM simulation of Full Scale Mill

This video produced in collaboration with Tega Industries shows how EDEM software can be used to simulate a full-scale mill. The ore rheology at different sections can be analyzed, and the pressure and wear on the shell liners can be predicted, enabling optimization of the mill’s design and operation. Additionally, by using EDEM sensors the discharge flow rate can be found, and more advanced analysis for carry-over and flow-back can be achieved.

Use Cases

EDEM simulation of Vibrating Screen

This video, produced in collaboration with HL Atacama, shows how EDEM can be used to simulate and analyze a Vibration Screening process. Sensors can be added to measure the total passed mass and data can be exported to analyze the screening process and estimate the efficiency of the decks. The screening decks can be colored by tangential or normal cumulative contact energy to visualize where the geometry is most likely to wear. Grid Bin Groups can also be added to find out where particles cluster.

Use Cases

EDEM simulation of Jaw Crusher

This video shows the analysis of the jaw crushing process for different materials (iron ore, limestone and granulite). The Tavares Breakage model in EDEM allows accurate modelling of the real process by simulating a continuous feed-rate and the complex motion of the swing jaw. The crushing process for different materials can be optimized and the need for sieve analysis minimized, by obtaining particle size data from EDEM. Equipment design can also be optimized by analyzing the forces and the wear on the crushing plates

Use Cases

EDEM simulation of Transfer Chute

EDEM can be used to evaluate and verify the design performance of transfer chutes and address key design challenges such as spillage, blockage and wear.

Use Cases

Cone Crusher Design Analysis and Comparison using EDEM

As part of a collaboration with Columbia Steel, EDEM was used in a project with the objective of comparing the throughput performance of two cone crusher mantle designs. The advanced Tavares Breakage Model was used to simulate the material breakage in the crusher, and the comparison and some of the analyses conducted in EDEM can be seen here. EDEM proved to be a highly useful tool for Columbia Steel to confirm the improvement obtained by the modified design.

Use Cases

Made of Steel - ArcelorMittal Optimized Sinter Cooler Charging System Using Altair EDEM®

ArcelorMittal is the world’s leading steel and mining company, with a presence in 60 countries and primary steelmaking facilities in 17 countries employing more than 190,000 people. In a recent project, a large-scale charging chute of a sinter cooler plant in Fos-Sur-Mer had to be optimized by the ArcelorMittal R&D team to improve the reliability and efficiency of this device. The objective was to identify a better and more feasible design that improved granular segregation, abrasion, and mechanical resistance. ArcelorMittal R&D used the high-performance software for granular material simulation EDEM to simulate and analyze the granular flows in the charging chute. Providing pre-calibrated material models, EDEM enabled the engineers to create and calibrate their EDEM model to match the physical experiments. The DEM simulation provided valuable insight into the granular flow in the charging chute and segregation patterns, which is difficult and sometimes impossible to measure in experiments.
