Most of the articles published are in Dutch. Two of them were translated:
Avoiding flow problems through adequate design.
To avoid problems in silos concerning flow, product ageing or decay, silo design is necessary.
The design of a silo is based on the most economical case: gravity flow. Wall friction, internal friction and bridging properties determine the applicable hopper angle and opening diameter.
In some cases through the design procedure it is found that a 'simple' silo is not possible. This however saves a lot of work and costs.
||Screw feeder design
Proper feeding through well designed pitch increase
In solids handling processes screws are often used to feed powders from silos.
This has a number of advantages: avoiding contamination, pollution and dusting; achieving proper feed rates;
However, if a screw feeder is not designed properly, core flow, bridging, flooding or excessive wear can occur.
A proper design prevents these problems.
