Full function gravimetric feeder for the price of a volumetric model.
 
MGF Gravimetric Feeder
Simple, Accurate, Affordable

The MGF proven loss-in-weight technology automatically calibrates itself, totally eliminating manual catch-and-weigh calibration procedures and even more common and erroneous guessing of metering rates.

  • No tools required for assembly or removal of load cell assembly, hopper and metering device
     
  • The throat adapter fits readily on most processing machine throats and easily supports nearly any main material supply hopper
     
  • Fast Clean-out and Replacement - Aluminum hopper with brushed exterior holds up to 25 lb of concentrate. Easy removal and replacement of supply hopper allows fast color change. Spare supply hoppers are available.

 

Eliminate Waste of Colorants and Additives
This compact loss-in-weight additive feeder precisely measures the amount of additive that is fed directly into the machine throat to eliminate costly waste.

Standard features:

For Injection or Extrusion
Quickly choose either the injection on extrusion mode and save.		 Easy-to-Use Microprocessor Controller Saves Time
Use-friendly controller has intuitive setup procedure
Reduces Input Error
The easiest setup procedure in the industry: enter let-down ratio and either shot weight or lb/hr output and press start. Feeder automatically adjusts to screw recovery time and extruder output.		 Detailed Documentation of Color Usage
Microprocessor control provides detailed records for entire production run, including shot-by-shot account of color dosing (Available September 2008)
Automatic Re-calibration Ensures Continuous Accuracy
Automatic adjustments guarantee that feed rate is held to within ± 0.2% of set point.		 Eliminates Downtime Associated with Color Change
Feeder automatically re-calibrates to new color so no additional setup required. Spare hoppers available for faster color changes.
Dual Load Cells
Balanced load readings improve accuracy		 Automatic Venturi Loading Device
Optional, fast hopper loading, upon signal from controller, when material level reaches 10% of hopper capacity
Torque-limiting Drive Coupling
Protects drive motor in case of jammed auger		  

 

Easy To Use Microprocessor Controller
• Large, user-friendly keypads for easy input
• Backlit LCD display
• Can be mounted remotely with optional extension cables
• Password protection		 Alarm light indicates low-load
(2-3 lb) in hopper

Conveniently located On/Off power switch and Run/Stop switches

 

Easy Set-up
Injection   Extrusion
Choose the mode of operation for your process: CYCLE for injection or CONTINUOUS for extrusion
Enter let-down ratio “LDR” and either shot size “SHOT / WT” or extruder output “LBS / HOUR” Press “ON” and “RUN”
As material is metered into the feed throat the dual load cells under the loss-in-weight hopper detect material usage Loss-in-weight data is gathered by the controller and monitored continuously Metering accuracy is held within ± 0.2%
