In-Vessel Composting: Rotating Drums BioCycle

Jun 21, 2007  Rotating drums are the most common in-vessel composting technology applied to mixed municipal solid waste in North America. The reason is that the combination of pulping action and biological degradation taking place in the drum breaks down the organic materials in just a few days to a rough compost that then can be separated from inorganic ...

Rotary Dryers - FEECO International Inc.

Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium. The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum.

Effect of grain shape on the dynamics of granular ...

We experimentally investigate the effect of the grain shape on the flow of granular material. The grain shape is modified to highlight the effect of grain circularity on granular flow in a 2D rotating drum. Using a laser cutter, we create particles with decreasing circularity. We observe that the effect of grain shape depends on the rotation speed of the drum.
