Transcript of Case Study Martin Engineering Eng
Martin Engineering in Brazil used EDEM to predict the flow behavior of ore through one of its transfer chutes and to design a new conveying system that generates a consistent and compact flow of material with reduced impact between mineral ore and conveyor.
The analyses performed by Martin Engineering reduced the impact force of the mineral ore on the conveyor belt by more than 40%. This effectively reduced the degradation in the transported material and increased the in-service life of the equipment.
Safer and more durable transfer chutes
CASE STUDY: MARTIN ENGINEERING, BRAZIL
artin Engineering is always on the look-out for cleaner, safer and more productive bulk material handling solutions. One of the Mengineering tools that Martin Engineering is using is the Discrete
Element Software, EDEM. This is used in the engineering design of transfer chutes and in the loading of railroad cars and silos for the mining company, VALE.

impacts from the ore.

- Simulation, analysis and visualization of particulate systems
Developed by the British company DEM Solutions, and exclusively distributed to the South American market by ESSS, EDEM
is capable of simulating processes and equipments involved in the transport and handling of particulate and granular materials.

New Design: After optimization, the new design generates a more aligned and consistent flow.
Identifying the peak impact loads of the mineral ore going throughthe transfer chute allows us to reduce the amount of protective coating
necessary and hence, the manufacturing costs. Moreover,
we are able to better understand the flow of the material and make
necessary adjustments to minimize mineral stagnation, thereby allowing
us to reduce the 'rock box' size and to design lighter equipment.
Material dispersion
Aligned and continuous flow
Initial Design: Mineral ore dispersion caused by the deflector.
Martin Engineering used EDEM software from ESSS to reduce the impact between the mineral ore and the conveyor, thereby reducing wear problems and increasing in-service life
Objectives
EDEM allows the design engineer to predict the behavior of the mineral ore through the transfer chute. It is
easy to change the geometry and come up with new designs to obtain
consistent material flow that is aligned with the conveyor belt. This
ultimately means reduced impact on the conveying equipment and
reduced wear thus increasing the estimated in-service life of the
equipment.
