Cooling water
Vol.20 #3, Dec. 1993

Most extruders use water to cool the feed section, gearbox, and barrel, as well as downstream devices. These items are all normally fed from a common water supply system. This can result in poor cooling in some areas of the equipment, if the pressure drop is not balanced across each cooling device.

Each separate cooling device should have an adjustable "balancing value" so that the devices with a low resistance to flow do not "hog" the cooling water, allowing the coolant to short circuit through a single device.
