The role and composition of the center feeding system of the extruder

The center feeding system is a part of the raw material system of the film production line and is responsible for the feeding of the main extruder. The main extruder has a production capacity of 3.5t/h. During the production process, the main material, recycled material, and additives are precisely dosed by the loss-in-weight metering feeder, sent to the mixing hopper by the pneumatic conveying system, mixed with the crushed trimmings recovered online, and then fed to the extruder by the loss-in-weight metering feeder which is synchronized with the extruder capacity. This article briefly introduces the role and composition of the center feeding system.

Here is the list of contents

• Usage of center feeding system

Composition of the center feeding system of the extruder

• Roots fan: provides power for the pneumatic conveying of the raw material to the mixing hopper.

• Loss-in-weight metering: a loss-in-weight metering feeder for main material, loss-in-weight metering feeder for recycled material, loss-in-weight metering feeder for additives.

• Rotary valve: effectively realize the continuous and batch supply of raw materials to the pneumatic conveying system to ensure the normal operation of the system.

• Vacuum feeder: The additive is automatically transported to the storage hopper above the loss-in-weight metering feeder.

• Cyclone separator: This device separates the raw materials, flaky crushed side materials, and high-pressure airflow from the pneumatic conveying to the mixing hopper.

• Dust collector: The high-pressure airflow separated by the cyclone separator also carries dust, which is removed by the dust collector.

• Metal separator: The raw material and flake crushing trimmings are removed from the metal material that may be carried into the melt chamber to protect the screw from damage.

• Mixing hopper: Mix raw materials, additives and flake crushed trimmings evenly and prevent the crushed trimmings from bridging and not feeding smoothly.

• Dosing loss-in-weight metering feeder: feeds the main extruder with precise dosing.

Usage of center feeding system

• Achieves 24-hour unmanned continuous forming operation

• Changeable forming machine with multi-species and multi-color material as required

• Fully automatic regeneration and use of cold material in the injection port

• Automation of the coloring process

• Centralized control of all mold temperatures

• Prevention of blockage in the storage bin

• Labor-saving through the installation of a central monitoring station

• Centralized transport of pellets in this system
