Extruder screen changer is a core part of recycled plastic production

The extruder screen changer is an indispensable equipment in the production of recycled plastics, which can be said to be the core part of the recycled plastics. The non-stop screen changer of the extruder can not only filter various impurities through the filter screen, but more importantly, after installing the screen changer for plastic extrusion, the filter screen can be replaced without stopping the production of the extruder and dismantling the mold. The specific screen changer The filter can also be replaced without affecting the normal production of the product, which reduces energy consumption, waste, cost and labor intensity of workers, and improves production capacity and economic benefits.

The basic configuration of the extruder screen changer is composed of the screen changer main body and the hydraulic power system, and an optional power distribution control system can be used to control the screen changing time. The screen changer of the extruder must be able to switch freely between the filter stations under normal working pressure, and it must also ensure no leakage, which puts forward high requirements for the quality and manufacture of the screen changer. Only qualified screen changers will leak. A qualified screen changer must first be reasonable in structural design, secondly guaranteed in material (high-quality alloy steel), again in processing technology and accuracy, and experience in post-assembly and debugging to ensure extruder replacement. Under the condition of high temperature and high pressure, the mesh device will not deform, always maintain precise matching accuracy, and will not leak material for a long time.

In the production of recycled plastic recycling, recycling and granulation are generally carried out. After the recycled plastic is crushed, it is cleaned, dehydrated and dried, and then granulated. The configuration of the granulation unit is generally composed of a feeder, a feeding device, a granulator, a hydraulic screen changer for an extruder, a granulation die, and a granulator. In the granulation process, it is divided into water-drawn strip granulation, water-ring granulation, and eager cutting. Different granulation processes and different production requirements have different types of extruder screen changers. The extruder screen changer provided by Zhengzhou Batte is divided into single plate double station screen changer, double plate double station screen changer, double column double station screen changer, mesh belt type automatic screen changer, all applicable For granulation production, different screen changers can be selected according to different working conditions and production requirements. info@battemachinery.com
