The production of pellets by Extrusion and Spheronization involves three
essential processes:
- Mixing of the dry powder components with a liquid to form a homogeneous and
evenly wetted mass
- Extrusion of the wet mass into cylindrical “spaghetti like” strands and
finally
- Spheronization which fragments the strands into short cylindrical lengths
and roll-forms them into spheres.
Equipment for all three processes are available from several manufacturers
and in the case of Mixers and Extruders, in a number of different forms. This
guide will first describe and categorise the basic equipment types available
and then give practical guidance on the use of Aeromatic-Fielder NICA™
System.
