Walthmac gravimetric pellets feeder widely used on the PPR pipe production line. It can real-time monitor the raw material feeding quality and control each layer thickness.
The Gravimetric Pellets Feeder by WalthMac is a revolutionary system that can significantly improve the quality level and machine stability of plastic pipe and film extrusion lines. It is an in-and-out closed loop control system that can control the raw materials extrusion inlet and the finished product haul-off speed simultaneously in real-time.
This system is designed to strictly control the meter weight and pipeline/film thickness, resulting in better quality control and more stable production. The Gravimetric Pellets Feeder can be used for all kinds of pipe extrusion machines, making it a versatile and must-have system for any manufacturer.
With its advanced technology and efficient design, this feeding system provides a reliable and accurate solution that can help manufacturers meet their production goals while ensuring optimal quality levels. It is a positive solution for anyone looking to improve their production process and streamline their operations.
System application field
Gravimetric Control System keeps the meter weight of products in uniform within the range of set value via measurement and automatic control for the extrusion line. It Widely used in kinds of pipe production lines. Like the PE pipeline and PPR pipeline and so on.

Part of the feeding system
Gravimetric Pellets Feeder isystem comprises several components that work together to ensure smooth and accurate operation.
①Data Acquisition Control Unit：Collecting data of meter weight in any time
②Screw Speed Acquisition Unit：Adopting the extruder's screw speed
③Display Control Unit：Inputting and providing changes of data to oprator to check
④Acquisition Unit for Linear Speed：Adopting the haul off speed
（1）The Data Acquisition Control Unit is the brain behind the system. It constantly collects data on the weight of the material being fed into the extruder and displays it on the control panel. This data is crucial in ensuring that the required material is being dispensed accurately.
（2）The Screw Speed Acquisition Unit is responsible for measuring the speed of the extruder's screw. This information is also displayed on the control panel and is used to ensure that the material is being fed into the extruder at the correct rate.
（3）The Display Control Unit is the interface that the operator uses to input and monitor the data. It provides a real-time display of the data collected by the Data Acquisition Control Unit and allows for adjustments to be made if necessary.
（4）The Acquisition Unit for Linear Speed measures the speed of the haul-off device, which is responsible for pulling the plastic material out of the extruder. This information is used to ensure that the material is being pulled out at the correct speed.
