Schwedes + Schulze Schüttguttechnik GmbH is a consultant company with powder testing laboratory. We work on tasks in the fields of silo technology, powder characterization and bulk solids handling.
Main part of our work is silo design for flow, i.e. the design of silos and other bulk handling equipment in order to attain reliable operation. Reliable operation means that problems as listed below will not occur:
- flow obstructions like arching and piping,
- stagnant zones,
- wide residence time distribution,
- segregation,
- unsteady flow and flooding,
- problems according to unsufficient interaction of silos, feeders, and conveying and dosage systems.
A second important part of our work is the measurement of flow properties of powders and bulk solids, e.g. flowability, internal fricton, compressibility, consolidation or caking during storage at rest, sensitivity to attrition, influence of temperature or humidity, etc. Some examples of materials tested in the past are: FGD-Gypsum, flyash, filter dust, coal dust, lignite, sugar, carbon black, fertilizer, animal food and components, metal powder, clay, iron ore, various crystalline and powdery, organic and anorganic chemical products, wood chippings, plastic granules, shredded waste, glass meal, cement, chalk, food products like fatty instant soup powder, and sewage sludge.
The services we offer:
Silo design for flow: Determination of the silo geometry (slope of hopper walls, outlet size, wall materials, inserts, feeders, discharge aids) which will exclude flow problems (arching, piping, irregular flow, flooding, segregation, product degradation).
On-site analysis of existing silos and related equipment and elaboration of concepts for reconstruction (retrofits) or optimization.
Measurement of flow properties of powders and bulk solids with shear testers (e.g. Jenike Shear Tester, Ring Shear Tester, uniaxial compression test) for silo design, comparative tests etc.
Measurement of the stress ratio at uniaxial compression (Lambdameter), wall friction coefficient and bulk density for silo design for strength, e.g. according to DIN 1055 part 6.
Development and optimization of feeders, dosing and conveying equipment, etc. which have to be suited to special conditions (e.g. uniform withdrawal and feeding of bulk solid, mixing).
