4 1/2 Inch EDS Compounding/Reclaim Extruder 

4 1/2 Inch screw diameter - 39:1 L/D ratio - With your choice of screw design - All screws have colmony 56 weld-on flite tips and double/high polish chrome (.002 Inches thick) is standard 

- Barrel has a cast-in bi-metallic lining extending throughout the 34:1 L/D ratio (a full 34 turns under heat) - screw has 39 turns when turns thru feed throat are included

- Barrel is vented with riser, diverter and stack to exterior of guards - Located 12 turns from end of barrel which maximizes the holding of forward pressure and reduces the potential of vent bleed

- Barrel is divided into 7 Heat/Cool Zones - heating is via finned cast aluminium heater jackets and cooling is via a 985 cfm (closely shrouded to the heater/barrel) Dayton fan on each zone

- Heavy duty double reduction Rossi Gearbox @ 17:1 reduction giving 100 screw rpm @ 1750 motor rpm input and 1:1 sheave ratio.  Gearbox is rated at 589 hp which offers a 2.36 Service Factor when used with a 250 HP drive system

- Heavy duty thrust bearing with B-10 rating of 300,000 hrs at 5,000 psi and 100 screw rpm.  Thrust bearing is integral to gearbox allowing precise alignment and 50% immersion of bearing in gearbox oil - both offer extended like to the gearbox/thrut assembly.  Gearbox and thrust assembly cooling is standard.

- Water cooled feed throat assembly - turned from a solid piece of tool steel.  This system offers superior strength and wear resistance over cast assemblies.  Actual opening of 5 1/2 Inch Wide X 12 Inch Longcut to the centerline of the screw - this style of throat allows high screw speed filling of the screw giving superior thruput and, along with high shear walls on the hopper, the processing of lower bulk density materials  

- Heavy gauge steel hopper with operator side sight glass and dump chute - high shear wall angles helps the weight of the material high in the hopper drive the material below it to the screw - it does not lay on the walls but instead the weight is more vertical, compressing the material below it to the opening area between screw flites  

- Tapered barrel flange with 3 piece head clamp with single bolt closure - includes clamp, lifter and support

- Belt driven variable speed 250 HP ABB Or Westinghouse AC vector drive with marathon vector duty motor - Motor is totally enclosed and blower cooled.  Drive module is chasis mount and mounted in main control panel complete with start/stop buttons, digital screw RPM meter, digital motor amp load meter and 10 turn POT.  Motor is mounted on main base in a Z configuration with motor beside the the gearbox.  This design creates a small footprint while allowing easy access for sheaves/belt maintenace or to modify screw speed range - machine is sheaved to 140 screw RPM unless otherwise advised

- Main control panel also houses electrical controls for barrel heating/cooling and drive functions.  The machine mounted over barrel main control panel consists of 7 barrel zones and 4 die zones - all controlled by RKC Mdl CB400 Auto-tune digital temperature control instruments.  Each zone will have ammeter indication of heater loading, branch fusing in addition to circuit breakers, mercury contactors for heater initiation (solid state can be subed at no charge) and solid state fan initiation

- Single point 460 Volt power connection thru door mounted disconnect

- (8) machinery mounting and leveling pads 

- 303 stainless steel breaker plate or open ring spacer

- Panel mounted Dynisco digital melt pressure and melt temperature indicator with barrel mounted pressure transducer and integral melt thermocouple - wired for customer setable high pressure drive shutdown

- Includes owner and installation manual with set of electrical drawings

- Painted your choice of colors with high temperature black motor and barrel covers

Optional:  Grate magnet mounted high in hopper to offer magnetic protection while not impeeding flow or the mass of material above feed throat providing compressed feed - supported by welded-in cross bars and located at start of taper in hopper - $1,840.00

Optional:  Hopper lid - 1/8 Inch thick X 1 Inch rim - $345.00

Optional:  Low level audible/visual alarm with silence button for hopper level indication - proximity sensor provided loose for customer installation or installed at customer direction - $580.00
