Design for Flow in Order to Avoid Flow Problems like Arching and Piping,
Segregation and Others.
of Existing Equipment. Troubleshooting..
We help you to
avoid problems with your powder handling equipment like silos, feeders etc.
For this, we offer a number of services such as:
Silo design for
flow (e.g. according to Jenike's approach): The silo geometry (slope
of hopper walls, outlet size, wall materials, inserts, feeders, discharge
aids) which is necessary to avoid flow problems (arching, piping, irregular
flow, flooding, segregation and silo quaking) will be predicted.
of existing silos and related equipment.
Elaboration of concepts for reconstruction (retrofits) of silos and related equipment (dosage devices, feeders) showing flow problems (flow obstructions, segregation, vibrations, etc.).
Comparison of flow
properties, e.g. of bulk solid samples with different compositions (e.g.
to investigate the influence of flow agents on the flowability and to find
the optimal flow agent concentration); evaluation of the influence of temperature
or humidity on the flow properties.
- Measurement fo flow properties for silo design for strength according to actual silo codes (e.g. DIN 1055 part 6).
Further fields of the work of Schwedes + Schulze Schüttguttechnik:
Flow of bulk solids
in any type of reactor, apparatus or machine (e.g. feeders, chutes, mills,
fixed bed reactors).
bulk solids handling equipment.
selection of measuring methods for quality control, product characterization,
measuring of stresses in silos.
feeders, dosage systems etc. which have to be suited to special boundary
conditions (e.g. uniform withdrawal of bulk solid, mixing).
stresses in silos and feeder loads; development of computer programs suited
to special types of feeders to calculate feeder loads and driving torques
in dependence on silo geometry and flow properties.
mixing of bulk solids in silos.
storage of bulk solids
Seminars and courses
on bulk solids handling (see alse here ).
