Feeding of Biomass: Design Experience with Wood Chips

By M. Rackl, Yuan Tan, W.A. Günthner Part of the international struggle to reduce the carbon footprint in energy consumption is the utilisation of biomass instead of fossil fuels such as coal or oil. Although the basic approach is quite promising, as there is a huge amount of usable biomass, there are some problems to be solved with regard to its application due to the largely differing form of appearance of the various base materials. In the following, some research into storage and handling of different wood products including DEM measures are presented. Continue reading Feeding of Biomass: Design Experience with Wood Chips

Design of a High Speed Transfer Chute in a confined Space – A DEM Case Study

By A. Edilbert , R. Spaargaren, C. Geijs, J. Ruijgrok, G. Lodewijks, D. Schott This paper aims to redesign a transfer chute as used in a Eurosilo system specifically for handling coal. The velocity of material vertically entering the chute was estimated at 15 to 34 m/s depending on the fill height of the silo. A three-stage approach was taken. First the existing situation with the highest velocity was modelled with DEM (Discrete Element Simulations), and the results of the wear profile on the existing chute were compared with practice. Secondly, three configurations were designed and the performance of these configurations in terms of wear volume were tested by simulation. Thirdly, and lastly, the performance of the configuration in terms of ensuring material flow through the chutes for a cohesive coal was evaluated. Based on the results of the simulation, two chute designs showed an improved performance where less wear was observed while securing flow through the chute.

EDEM: Simulation of the Powder Raking Process in Additive Manufacturing

Edinburgh, United Kingdom This simulation models over 8 million particles of less than 0.3mm in size. Large amounts of tiny particles are common in Additive Manufacturing applications. This video shows powder raking and how EDEM tools can be used to analyze voidage, particle orientation and number of contacts at different time steps. Similar simulations can guide the design and optimization of the powder rake and its speed.
