Gravimetric dosing

GRAMIXO
Continuous loss-in-weight batch dosing unit

GRAMIXO is a gravimetric batch dosing system with continuous loss in weight control that can handle up to six ingredients. It features a removable inclined mixer and easy access openable transparent body panels.

The management system is integrated with the extruder control, with the haul-off and with the thickness control. When applied to blown film production, the cooling ring can be managed by GRAMIXO to further enhance the stability and performance of the production line.

GRAMIXO has specifically been designed for extrusion applications where weight per meter control is paramount.

  • Double eyelid shutter
  • Removable inclined mixer
  • Vibration immunity system
  • Quick Recipe changes

 

GRAVICO
Continuous loss in weight multi-component dosing system

GRAVICO is the continuous loss-in-weight multi-component dosing system equipped with an automatic linear weight/meter adjustment that finds application in all plants for the continuous cycle processing of plastic materials (films, pipes, profiles, mono and co-extruded sheet).

GRAVICO is designed for using up to eight ingredients and is suitable for a large number of configurations. GRAVICO is automatically managed by NAVIGATOR 9000 for the automatic management of all production parameters.

  • Multi-component
  • Vibration immunity system
  • Throughput control
  • Quick start-up time and changeover

 

GRAMETRO
Weight/meter control

GRAMETRO is a continuous loss-in-weight gravimetric dosing unit designed for extruder feeding and supervision.

It manages the weight-per-meter ratio of the extruded material in a closed loop. A control algorithm supervises the haul-off speed in combination with the extruder, thereby keeping a constant quantity of extruded material for every linear meter, also in multilayer applications.

  • Consistent extrusion feeding
  • Self-adapting
  • Throughput control
  • Quick start-up time
  • Automatic calibration

 

 

GRAMIKRO
Continuous micro blender

Continuous loss in weight multicomponent dosing system, designed for precision dosing in extrusion systems that require regular flow and a constant blend. All components are based on a loss-in-weight principle and dosing percentages are managed by the NAVIGATOR 9000 control.

GRAMIKRO is compatible with starve feed extruders and features vibration immunity for installation directly on the extruder.

  • Multi component
  • Suitable for starve feed extruders
  • Vibration Immunity system
  • Production control
  • Quick start-up and production changes
