Discrete element modelling of screw conveyor-mixers
screw conveyor, with addition of new elements welded on the helix of screw conveyor, in order to increase the effect of auxiliary mixing along with the transport of particles. In this way a screw transporter could be con-sidered as transporter and also the continous pre-mixer. Discrete Element Method (DEM) was used to

Discrete element modelling of screw conveyor-mixers. Jovanović Aca, Pezo Lato, Stanojlović Sanja, Kosanić Nenad, Lević Ljubinko. Screw conveyors are used extensively in food, plastics, mineral processing, agriculture and processing industries for elevating and/or transporting bulk materials over short to medium distances.
Modified screw conveyor-mixers – Discrete element modeling ...
The influences of screw length, observed geometry variations and different types of screw design, on the performances of the screw conveyor-mixer during material transport were explored. The auxiliary mixing action (used to improve the mixing process) was achieved during the transport of the material.
Discrete element modelling of screw conveyor-mixers - CORE
Screw conveyor performance is affected by its operating conditions (such as: the rotational speed of the screw, the inclination of the screw conveyor, and its volumetric fill level). In this paper, horizontal, several single-pitch screw conveyors with some geometry variations in screw blade was investigated for mixing action during transport, using Discrete Element Method (DEM).
