USED 20 DENIER MONOFILAMENT PILOT UNIT LINE CONSISTING OF THE FOLLOWING:
Line Components :
1. Unadyn Dryer System
2. Dry Chip Bunker
3. Extrusion
4. Quench
5. Take Up
Unadyn Dryer System :
Dryer systems consists of the following :
1. One 10 hp vacuum pump ( made by Conair ) to move chips form storage silo to crystallizer, one vacuum loader to receive them.
2. One Model XTLR 300 crystallizer, with heater, fan, and controls.
3. One UDC 55 air treatment unit, dry air for dryer only
4. One MSC 300 # Modular hopper for chip drying.
Currently the crystallizer is on top of the dryer hopper with a hand valve to separate both vessels.
Dry Chip Bunker :
One dry chip bunker feeds the unit, the tank has a capacity of about 280 lbs ( sitting above extruder ).
Extrusion :
One 1.5 inch Davis Standard 30:1 extruder ( obtained in 1999, std screw ), with a 10 Hp A/C drive motor, gearbox has a ratio of 11.33 :1, 100 rpm maximum speed. Four heating zones ( no cooling ), plus throat cooling loop. Electrically heated transfer line to a single position, Zimmer type spin beam ( 1999 vintage ), spin beam is dowtherm heated. The position has a pump block for two dual port 2.4 CC/rev pumps ( Feinpruef ), each pump feeds two ( 2 ) 79 x 79 mm packs, polymer pump motor of 0.8 hp and gearbox of 25:1. Polymer melt pressure and temperature monitor points. Each spinneret has 6 holes arranged in a semi circle ( total of 24 ends for the position ). Controls, individual temperature controllers for each heat zone, plus extrusion pressure control. One a/c inverter to drive the polymer pump drive motors, one motor drives two pumps.
Quench :
One quench cabinet per pos. 12 inches wide by 72 inches long. A binded screen pack is used to feed quench air to filaments. Metered stream finish application at the bottom of the cabinet ( two 12 port pumps )
Take Up :
Godet pedestal stand for two 150 mm chrome coated godets.
Over the winder 150 mm godet.
One row of winders three high ( frame by Comoli ), Comoli winders type WTU 450 ( vintage 1992 ), 8 end per chuck, 55 mm traverse. Mechanical speed 2,000 m/minute, running speed for product 1,000 m/minute winder maximum package size is 400 mm for current layout ( nominal for current product 360 mm ). Current bobbin is 94 mm id x 75 mm long x 5 mm thick. Total winders in one line : 3. One traverse a/c inverter and one drive roll a/c inverter for all winders.
Capacity :
Current line is set up to run 24 ends, this gives a gross output of about 26.75 lbs. per hour. Line can also run 10 to 27 denier monofilament.
