Redesign and evaluation of pebble crusher feed
Vastec Engineering AB helped redesign a mining company’s pebble crusher feed system. The original setup caused size segregation and stress on components. Maintenance was hard due to conveyor position and height limits. Using DEM simulations, we optimized the system. The new design ensures better particle distribution and improved efficiency.
Simulation of wear in rope shovel buckets
Research project were DEM simulations were used to simulate the wear on large scale rope shovel buckets.

Simulation of rope shovel bucket filling dynamics with DEM-FEM
This was a research project where rope shovel in Bolidens Aitik open pit copper mine was studied. DEM-FEM models were calibrated and used for full scale applications on rope shovel bucket filling.

DEM Simulation of full scale AG-mill
Simulation of a full scale AG mill to evaluate charge behavior at different wear levels of the liner as well as mill speeds.
Simulation of discharge flow. Evaluation of mill discharge designs. Simulations performed for dry conditions.
Redesign of dust hood collector
Vastec created a computational fluid dynamic (CFD) simulation of a board profiler machine. The goal was to propose and simulate new designs for the dust collection hood. A single phase CFD model was created and passive scalars transport were used to track dust particles.
