 LW Series:

Continuous type gravimetric dosing unit

(For Dosing and Line Control)

Applications:

    ● For extruder machines

    ● Extruder output supervision

     Gram per Meter control

     Precise layer control in a multi-layer extruder line

    ● Fast control during ramping using Cotex Control

Features:

     Stainless Steel construction

    ● Semi-automatic calibration

    ● No need for tuning or setup when replacing materials

    Weighing bucket sizes from 0.5 to 50 liters

    Capacity range from 10gr/h to 4000 kg/h per channel

    ● Standard Omron PLC control

    ● Single off center load cell per channel

     Additives feeding using screw and or belt feeders

(The belt feeders have the unique ability of 1:1500 feeding range)

Principle of Operation:

The main material is fed directly into the extruder using a loss in weight hoppers. The measured throughput is used to synchronize the additive feeders.A special MODELING type of control compensates and reacts accurately even during vast RPM changes.

The line speed is measured using digital or analog interface and the extruders are adjusted accordingly.

Precise layer control in multi-layer lines. Layers are distribution by either thickness or mass proportion. Product dimensions can be presented in either gram-per-meter or average thickness (microns).

 GraviMan ™

Continuous weighing unit

Applications:

    Extruder output supervision

     Gram per Meter control

    ● Precise layer control in a multi-layer extruder line

Features:

    Stainless Steel construction

    ● Semi-automatic calibration

     No need for tuning or setup when replacing materials

    ● Weighing bucket sizes from 3 to 50 liters

     Max capacity for 50 liter 2000 kg/h

    ● Standard Omron PLC control

     Single off center load cell

Principle of Operation :

Extruder output supervision – Receives the extruder RPM through digital or analog interface, presents the extruder output rate on a display panel

Gram per Meter control – Measures the extruder capacity, receives the line speed through digital or analog interface and adjusts the extruder’s RPM to maintain the correct gram/meter

Precise layer control in a multi-layer extruder line – The PLC receives the total desired output from the extruder’s operation control and each extruder’s RPM is then regulated according to the desired percentage while maintaining the total output of the line
