PARKER HANNIFIN CORP. ZENITH PUMPS DIV.

PEP-II series gear pumps serve as a pressure booster/stabilizer on the discharge end of an extruder and for precise additive injection into the extruder barrel. Constructed of through-hardened, high-speed tool steels or 400-series stainless for corrosion and wear resistance.

PEP-II gear technology utilizes low-aspect-ratio "crowned-root" gears. With L/D ratio of 0.75 vs. industry standard of 1.0 for helical gears, PEP-II ensures polymers have less distance to travel, thereby reducing tooth pulsations. Crowned roots are parabolic-shaped undercuts, which offer less resistance to tooth evacuation flow and further tooth-pulse reduction. Company reports that the combination of crowned root and low-aspect ratio gearing provides superior extrusion performance, superior mechanical integrity, and greater efficiency than conventional designs.

POMINI, INC.

Intensive, twin-rotor batch mixers and LCM long continuous mixers precisely control mix quality in processing operations such as densifying, direct color compounding, pigment master-batching, polymer alloying, and compounding with fillers, plasticizers, and foaming agents. Resembling a twin-screw extruder, LCM is a continuous mixer with two nonintermeshing counterrotating, wing-type rotors. The 10:1 L/D mixing chamber has two distinct mixing zones with independent temperature control. Transport of material, dispersion of ingredients, and preheating take place in first zone. Melting, mixing, homogenizing, and discharging of the compound, once it has reached a predetermined temperature, are carried out in second zone.

LCM-AX is an in-line combination of long continuous mixer and twin-screw extruder in one machine barrel. It is designed for process flexibility. Screws are corotating and intermeshing, and have a mixing zone with the rotor-blade profile of the LCM. Downstream from the mixing zone is a hydraulic throttle valve, which controls dwell time and specific energy input. With this control flexibility, a wide range of polymers and engineering plastics can be compounded on the same machine without the need to reconfigure screw geometry. With a secondary feed zone downstream from the rotor section, glass fibers and other delicate reinforcements can be safely added and uniformly distributed without breaking the fibers.

Turnkey, custom-engineered batch or continuous compounding lines can be provided complete with upstream and downstream support equipment and customized automation. (Se ad p. 232.)

DALTON ELECTRIC HEATING CO., INC.

Watt-Flex split-sheath cartridge heaters with continuous coil reportedly give uniform temperature profile, often eliminating need for distributed wattage. Because unit has no coil segments and cold spots of conventional heaters, it is suitable for package and bag sealing bars. Hot-tip feature, accomplished by passing the coil across the tip of the heater, improves performance of sheet extrusion die or hot-runner gate probe by putting more responsive heat in the lip of the die or tip of the probe. Independent, bilateral expansion of the two legs effects contact of both sides of the sheath to a bore, providing better heat transfer and consequently a cooler-running coil. As heater is de-energized, it contracts, making heater removal easier and eliminating bore seizure. Grooved heaters externally accommodate needle-type thermocouples, which monitor process temperature, not internal coil temperature. Design allows independent replacement of thermocouple or heater.

Polycyclone separation system consists of 50 small hydrocyclones in three vertical tiers. Water slurry of ground plastic flake is fed under consistent head pressure from a large manifold downward through tiers of 20, then 18, then 12 hydrocyclones of 6-in. diam. Tehe prototype is available for customer testing and processes 4000 lb/hr.

ANDRITZ SPROUT-BAUER, INC.

ASB post-consumer film reclaim system continuously processes one metric ton/hr of thin films such as HDPE and LDPE into flake or pellets. Preshreds bales and feeds them to the washing tank where detergent is automatically added and further shredding/agitation occurs. Heavy contaminants are removed at this stage. While in wash solution, material is cut to size with patented DSF film cutter, capable of cutting films down to 0.25 mils thick.

After cutting, wash water is removed on a Hydrasieve static screen, filtered, and recycled. Ground film is dewatered in a screw press and transported to rinsing area where a series of Hydrasieves removes remaining fiber and other contaminants. Effluent from this section is filtered on ASB Micrasieve pressure screens to remove fiber from rinse water. Cleaned water is recycled. Rinsed film is dewatered again in a screw press and dried to less than 1% moisture.

System is modular with several segments prepiped, prewired, and mounted on structural steel for connection on site. Pilot system available for testing.

AUSTRONIC INSTRUMENTS INC.

Indumat recycling system is a completely self-contained unit operated by one person. Infeed conveyor loads film, tape, bags, etc. into the shredder, which preheats the material while cutting it into small pieces. Preheated material is forced directly into the extruder, which is connected tangentially to the shredder drum. Preheating material reportedly-saves approx. half the horsepower in subsequent extrusion. (A preheater can be substituted for the shredder when using granular regrind.) Extruder has a coarse filter ahead of the slide-plate fine filter. By removing large contaminants, the coarse filter prolongs the life of the fine filter. Automatic backflush also adds to fine-filter life. Hot die-face or strand pelletizing completes the process.

MATCON USA, INC.

Discharger/valve, which bolts to the discharge of a silo, consists of a hopper and an inverted cone within it. At rest it acts as a sealed valve for a dust-free atmosphere. On demand the cone rises and vibrates, allowing material to discharge through the resulting annular gap. Once open it continues to vibrate, becoming a fully automatic discharger and bridge-breaker, promoting a free flow of material. Variable throughputs are obtained by increasing or decreasing the height of the cone and by pulsing the machine on and off.

Discharger/valve can be used on new and existing silos, discharging and controlling the flow of solids from storage, or as a prefeeder for accurate gain-in-weight and loss-in-weight feeder systems and for automatic filling or packing lines. System is suitable for topping off feeder hoppers on demand, because it maintains a constant bulk density and avoids overworking the material.

WYSSMONT CO., INC.

Turbo-Dryer has only two moving parts: tray/shelf assembly and fan assembly, both rotating independently in a fixed sealed housing.

Wet feed enters the Turbo-Dryer through a feed chute in the roof of the housing and flows onto the first shelf. Shelves are circular with cut-out center and radial slots and are rigidly mounted on an inner supporting frame, forming a vertical stack, which rotates slowly as a unit. Material flows onto each shelf from the one above, forming a pile. The rotation of the tray/shelf assembly carries the pile past a stationary blade set to level the pile to fill the tray at a uniform height. At the end of a revolution, the tray segment meets a second stationary blade set to wipe the tray clean of material. Material is held stationary by the wiper blade, while the tray continues its rotation. Material flows through the radial slot onto the shelf below, where the cycle is repeated. Material progresses downward from shelf to shelf through the dryer and is discharged through a chute in the housing bottom.

Air or other drying medium is fed to the Turbo-Dryer through a side-mounted vertical manifold with control dampers. Air movement inside the dryer is provided by centrifugal fans mounted on a single vertical shaft. Fan assembly fits in the center of the shelf assembly, rotating independently of the shelves. Drying medium leaves the dryer through a roof exhaust.

Turbo-Dryer housing, totally sealed, encloses and supports both tray/shelf and fan assemblies; supports stationary parts of the dryer, wipers and levelers; and consists of a metal frame and insulated side panels, roof, and bottom.
