Minimization of wear in a transfer chute by geometric optimization of convex pattern surface: A DEM study

Using bionic surface on the material equipment interface of bulk handling equipment is a promising solution for wear reduction. A bionic surface is a flat surface outfitted with a pattern of convexes that disrupt the natural sliding flow of bulk material. Previous numerical work has shown a significant reduction of wear of bionic surfaces...

Biomass pellet breakage: A numerical comparison between contact models

The breakage behaviour of biomass pellets with a diameter of 6 mm under uniaxial compression test was studied experimentally and numerically using the discrete element method (DEM). Two types of the available bonding contact models in EDEM software were used to compare the macroscopic properties including the maximum stress at failure, strain at...

The Effect of Pellet Length on Mechanical Durability and Breakage Behaviour of Torrefied Biomass

The transportation, handling, and storage of biomass pellets are challenging due to pellet breakage and fines generation. The amount of fines generated during transportation and handling of biomass pellets is mostly measured in the laboratory using mechanical durability testers such as tumbling can method according to ISO 17831-1. This standard...
