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).
