What is mass flow?

With mass flow the whole contents of the silo is moving, as soon as product is extracted from the silo.

This type of flow is characterised by:

• first in - first out;
• little segregation;
• steady flow and a well controllable discharge-capacity;
• no risk of ageing, decay, or contamination;
• possibility of 'following' product batches with a specific composition.

Disadvantage of mass flow can be that in certain cases silo quaking can occur. When dealing with abrasive products, the silo wall will wear quicker. In general this will not be problem, because of the low flow velocities in a silo.
