Gravimetric System on Extrusion Line

Product Description

    GraviMac Series-Online Measurement and Control System of Per-meter

****- A Quality Measurement System Based on Weight***-

1.Shorten the start-up time
2.Saving of the raw materials
3. Reduce the quality risks of plastics pipe production and improve quality.
 

The applications:

The process control for the production of plastics pipes, film, etc.
 

 The function:

The system is installed on an extruder to measure and calculate per-meter weight and extrusion output, and also controlled by closed loop, which realize

the constant weight ofper- meter and make it operate at setting values.
 

 Precision error:

< 0.3�0.5%(Differs from the different raw materials and machines)
 

The available materials for GraviMac:

• The powdery
• The pellet / Granular
• The fine powder( good flowing properties)
• Mixture or Untreated material/ Fine powder or Small spherical / powdery(good flowing properties)
• Rubber(Granular)

—�The measurement and control parameters that can be setting in GraviMac

¥The output of extruder

Unit: kg/hr

Control the output by controlling RPM of the extruder)

ï¹¥Per-meter weight

Unit: kg/m, g/m

Linear speed is needed;

Control the weight of per-metre by controlling the linear speed.

ï¹¥Statistical function

Count the consumption of raw material and the length.
