The powder coating line comprises of a 16 mm twin screw extruder with 24 L/D coupled to a chill roll unit which will form thin flakes of the compounded thermo-setting resin. The twin extruder is equipped with 6 barrel modules, each of 4 L/D length which are equipped with either cooling or heating or both.

Since the powder and the liquid feeder were validated independently of the extrusion system, further investigations in extrusion were required. It was unlikely that the extrusion process was affecting the powder feed rate because there was no mechanical connection between the powder feeder and the extrusion barrel.

Feeder agitation type: Make sure the agitator in the filler feeder isn't aerating the material and reducing the bulk density. Many feeder manufacturers have special agitator designs for powders. Make sure stuffer hopper is vented: Along with the filler, the stuffer also introduces a lot of air into the extruder.
