Investigating the effect of the feeding arrangement on screen media wear and screening efficiency by using DEM
Artikel i övriga tidskrifter, 2021

The discrete element method (DEM) is an effective tool for studying particles and
equipment interactions in comminution and classification processes. Comminution and
classification process performances are dependent on the operational conditions of
different units. For screens, the performance of the particle separation is affected by the
wear on the screening media. This work aims to study how screening performance, along
the deck, is affected by different feeding arrangements, and how it influences screen
media wear. A series of DEM simulations were configured to different feeding
arrangements and validated with data from a crushing plant. The simulation results and
process data show how screen media wear patterns can appear in a different section of
the screen and how significant their effect is on the screening performance along the
deck.
