Screw Cooling (Dec99)

Screw cooling (Dec99) Vol. 26 #3, December 1999

When the screw is being cooled in the feed section, make sure there is sufficient flow of water and the line is free of scale, especially when the cooling tower water is used. Lack of cooling, due to restricted or low water circulation, has caused rate loss and extrusion instability in large extruders. This is often an overlooked monitoring point in an extrusion process.
