Product Spotlight: GRAVITROL® Extrusion Control Systems

GRAVITROL® Extrusion Control Systems: The Complete System

This week Process Control Corporation is pleased to spotlight its GRAVITROL® Extrusion Control Systems. Gravitrol® extrusion control offers the benefits of improved product quality, reduced material usage, quicker startups and product changeovers, reduced scrap, and improved product repeatability. At the same time, it reduces the operator’s workload by maintaining a constant output, regardless of screen pack or material variations.

The system uses Process Control’s proven Gravitrol® software to automate the control of the line and hold the extruder output to +/- 0.5% by weight. This tight control of output means that product can be made consistently within tolerance at the lowest possible cost, thereby saving thousands of dollars in resin.

Process Control X Series blenders can be equipped with extrusion control software to allow the blender to control the extruder and line speed on monoextrusion lines for consistent output by weight. Guardian® batch blenders can also be equipped with weigh hopper and extruder and line speed I/O.

Control for X Series 2 Blenders
Process Control X Series 2 blenders monitor the extruder usage in order to follow the extruder rate and insure a consistent supply of material. In an extrusion control system, this extruder rate is used to adjust the screw speed by minute amounts to hold the overall throughput to the value entered in the blender operator station. Because the blender already has a  powerful computer and equipment necessary to measure the extruder rate, adding extrusion control on a monoextrusion line with a Process Control X Series 2 blender is a very cost-effective addition. This feature can be easily retrofitted to existing installations with X Series 2 or B Series blenders.

X Series 2 blenders can also be easily integrated into coextrusion applications with extrusion control for controlling product layer ratios and total line throughput. On coextrusion applications the blender computer reports to a master EXB2 Series Operator Station, which also receives weight throughput reading from HG Series 2 Weigh Hoppers mounted on single-component extruders.

Completing the ASR Part Three: The GF Series Film Grinder

The recovery of scrap generated during the production of blown film, cast film, tape and extrusion coating processes is a key element in reducing manufacturing costs. The Automatic Scrap Recycling system – or ASR®, for short – can recycle trim scrap and off-spec roll scrap in-line and turn your scrap back into profit without the expense of repelletizing.

A complete ASR system consists of several components, and for the next three weeks Process Control is pleased to detail this patented Automatic Scrap Recycling system. The three components covered will include the following: The RMX Series Refeed Machine, the IN Series Trim Removal Inducer, and the GF Series Film Scrap Grinder.

This week, PCC would like to highlight the features of our GF Series Film Grinder for automatic scrap recycling applications.

The GF Series grinders from PCC are used as part of an ASR Automatic Scrap Recycling system for in-line recycling of production film scrap. GF grinders are designed to provide efficient, uniform grinding o film scrap. There are four cutting chamber sizes available along with different horsepower motors to accurately match the grinder to the scrap rate. Grinders are available in configurations that accept edge and bleed trims, roll scrap, and loose scrap.

Standard carbide-coated knives are employed in the system, increasing the time between sharpening. The rotor knives approach the stationary bed knife, or knives, at a steep angle to ensure a clean scissor cut. This technique is used for maximum bulk-density and flow of ground scrap. The open rotor design improves airflow for cooling, permitting the highest possible throughput.

Completing the ASR Part Two: The IN Series Trim Removal Inducer

The recovery of scrap generated during the production of blown film, cast film, tape and extrusion coating processes is a key element in reducing manufacturing costs. The Automatic Scrap Recycling system – or ASR®, for short – can recycle trim scrap and off-spec roll scrap in-line and turn your scrap back into profit without the expense of repelletizing.

A complete ASR system consists of several components, and for the next three weeks Process Control is pleased to detail this patented Automatic Scrap Recycling system. The three components covered will include the following: The RMX Series Refeed Machine, the IN Series Trim Removal Inducer, and the GF Series Film Scrap Grinder.

This week, PCC will be featuring the IN Series Trim Removal Inducer.

IN Inducer

Process Control’s IN Series Inducers are designed to pick up and convey edge and/or bleed trims generated in the production of plastic film or other thin-gauge products such as foam, tape, paper or foil. These continuous trims are picked up by suction, conveyed into the inducer’s venturi section and blown to a destination such as a Process Control film grinder or a waste container.

Process Control inducer manifolds are designed to insure that the air velocity at the pickup point is maintained so that the trims do not wrap around the cutters. The IN Series inducers feature an adjustable venturi to allow you to tune the inducer for peak performance with your installation. IN Series inducers have a higher induced air to primary air ratio than conventional trim removal systems, providing excellent pickup and conveying performance.

IN Series inducers are designed to adapt easily to the installation requirements of your extrusion lines. The unit is shipped with its fan in a top-horizontal arrangement, but can be easily rotated in 90° increments to provide the required fan/venturi orientation. The fan may also be mounted remotely from the venturi using additional tubing.

Equipment Diagram

Process Control’s patented venturi design uses the same principle used to create lift with an aircraft wing. The venturi design is far more efficient than the more commonly used cyclonic design, resulting in more suction and far greater air flow per fan CFM. This efficiency reduces the required horsepower, which results in lower energy costs, reduced noise and easier separation of the trim from the conveying air at the grinder.

Completing the ASR Part One: The RMX Series Refeed Machine

The recovery of scrap generated during the production of blown film, cast film, tape and extrusion coating processes is a key element in reducing manufacturing costs. The Automatic Scrap Recycling system – or ASR®, for short – can recycle trim scrap and off-spec roll scrap in-line and turn your scrap back into profit without the expense of repelletizing.

A complete ASR system consists of several components, and for the next three weeks Process Control is pleased to detail this patented Automatic Scrap Recycling system. The three components covered will include the following: The RMX Series Refeed Machine, the IN Series Trim Removal Inducer, and the GF Series Film Scrap Grinder.

Today PCC is happy to show off its RMX Series Refeed Machine. This machine is specifically designed for use with Gravitrol® Gravimetric Extrusion Control Systems. The compact size also makes the RMX Series suitable for applications with headroom restrictions without sacrificing the performance that has made the ASR® Refeed Machine popular for film applications. The unique, double-compartment RMX Series Refeed Machine operates with a variable-speed auger/bridge-breaker assembly to compact and meter ground scrap from the inner hopper to the throat of the production extruder. The outer compartment contains virgin material which is gravity-fed to the throat. The virgin material completely surrounds the ground scrap as it enters the extruder. The extruder screw receives a consistent column of compacted ground scrap surrounded by virgin material.RMX

This method provides consistent operation without extruder surging or starvation. With the standard extruder follower circuit, the refeed machine will increase or decrease the scrap rate in proportion to the extruder speed. This holds scrap percentage constant without additional operator attention. The touch screen operator panel with smart HMI provides full control and configuration of the drive system with minimal setup. The roll feeder and refeed status may be monitored from a single screen.
