“Schwedes + Schulze Schüttguttechnik” is a consultant company with powder testing laboratory. We work on tasks in the fields of silo technology, powder characterization and bulk solids handling. 

A 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. These tests are important, for example, for comparative testing, product optimization (e.g. optimum percentage and type of flow agent, influence of variations of the production process), quality control.

The philosophy of "Schwedes + Schulze Schüttguttechnik" is to solve practical problems in the field of bulk solids handling (silo design, measurement of flow properties) on the basis of the mechanical properties of the bulk solid under consideration. Only this way reliable solutions can be achieved.  Even at the measurement of flow properties we concentrate on well-defined, physical quantities, which can only be measured with appropriate shear testers.

In the past we have tested several hundreds of different powders and bulk solids. Thus, we have an extensive experience which helps us to work effectively on future problems. Some examples of materials tested in the past are: FGDGypsum, 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.

Although we have the experience from all materials tested in the past, most problems which have to be solved require qualified testing of the materials under consideration in order to obtain a reliable solution. Alone the name of a bulk solid is no sufficient characterization of its flow behaviour, since usually products with the same name, but of different origin show differences e.g. in particle size, particle shape and humidity, and thus in their flow properties.
