Running a small polyolefin pipe
extruder with a high-speed "hyper drive" doubles output without any extra gear wear, says Cincinnati Extrusion, Erlanger, Ky.
The gear-pump
extruder, highlighted in the literature, is a continuous process.
Options: Oriented discharge and trim, broad range of
extruder throughputs.
Session 2 on pump equipment will discuss the screw
extruder, ram (preform)
extruders, auxiliary devices, drives and transmissions, and temperature control.
CTE's technology has one short and one long screw side by side, changing from a twin-screw kneader to a single-screw
extruder.
Many extrusion process engineers never get the opportunity to design an
extruder screw, given that prices for custom-made replacements can rival the cost of a new SUV.
Double-sigma blade mixer in carbon steel available with
extruder discharge.
Use proprietary grinding and drying technology and a conical single-screw
extruder connected to a polycondensation reactor, which upgrades PET's I.V.
A dual-purpose twin screw
extruder system has been introduced for use in wide ranging color and related dispersive mixing applications.
Macchi's syn-torque line had one 7000-Nm Siemens motor and Knoedel/SKF thrust bearing on the 80-mm main
extruder, two 5000-Nm torque motors on each of two 65-mm coextruders, and 200-Nm syn-torque motors driving nip and chill rolls, where they reportedly provide more precise tension control than do servo motors.
This manufacturer of thermoplastic
extruders has introduced a line of single screw
extruders designed for compatibility with screws from other
extruder manufacturers.
Fillers are added where the cutter/compactor precuts, prewarms, and mixes material before it enters the
extruder. The result is said to be less expensive pelletized material for film with higher properties.
