DRIVE UNITTheACdriveandpowerunitisdesignedtohandlethe typical range of polymer requirements.A direct-coupled motor provides efficienttransmission of power to the gear reducer.The drive is housed in an electrical enclosurewhich can swivel around the support column toprovideoptimumoperatorpositionrelativetotheextruder.

GEAR REDUCER & THRUST HOUSINGThegear reducer isaparallel shafthelicalgearunit. Gearing is manufactured from alloy steeland is hardened and ground. The standardoverall gear reduction ratio is 17:1 nominal, toprovidearound100 rpm feedscrew speedwhenthe reducer is driven at 1750 rpm. The drivetorque capacities are sized to be suitable formost commonlyprocessedmaterials. The thrustbearing is sized for 60,000 to 100,000 hoursL10 life based on actual operating conditions.Internalsareimmersionlubricatedandthethrusthousingbearingsaregreaselubricated.

FEED SECTION & HOPPERThefeedsectioniscastingcoredforwatercooling.It incorporates an air space to minimize heattransfer fromthebarrel tothegearreducer,andalsoprovidesmaintenanceaccesstothebushingand thrust shaft socket. For feeding efficiency,the feed throat is angled back30degrees fromperpendicularwiththefeedscrewbore.Thehopperis constructed of stainless steel and includes aslideshut-offgate,sightglass,anddumptube.

HEATING AND COOLINGEach barrel zone is fitted with a bolt-on castaluminum heater. Each barrel control zone hasa separate motorized blower. The blowers areattachedtothebottomofindividualairshroudsmountedaroundeachheaterzone.

EXTRUDER SCREWStandard feedscrews supplied with theHPE machine are single-stage mixing typechrome-platedfeedscrews.

HEAD FLANGEA standard four-bolt flange is provided withthe die. A clamp flange and clampassembly isoptional. The flange has a pressure top at the12 o’clock position for a supplied mechanicalpressure gauge. A transducer is optional.Over-pressurization protection is providedby a 9,000 psi (620 bar) rupture disc at the6o’clockposition.
