What are the factors that affect screen changer lifetime

Screen changer is widely used in polyester and spinning production line. Its main purpose is to remove solid impurities such as organic melt, carbonized particles and metal oxides in melt, improve product quality, provide qualified raw materials for downstream process and ensure normal production of downstream process. Therefore, the factors affecting the service life of the screen chqnger filter element are analyzed and the device is technically reformed, which prolongs the service life of the

Casting sheet for non-stop screen changers

The special non-stop screen changer for casting, sheet and sheet material adopts multi-network reciprocating filtering technology, single channel or multi-channel screen changer filtering at the same time, with self-contained voltage stabilization and mobile automatic exhaust mechanism, which has better sealing and wear resistance than the ordinary fast screen changer. When changing the screen, it does not stop the machine, keep feeding and affect normal production. Common fast switching device

Prevention of adverse effects of mesh screen changer on extrusion molding

The screen changer (filter) is an automatic switching device consisting of one or more filters, which is used to filter out the particles and impurities contained in the plasticized material flow filter. The filter screen is supported by an alloy porous plate or wire mesh. The porous plate or wire mesh is installed on the carrier of the filter. The carrier is driven by hydraulic cylinder to switch between the working position of a system and the off-line non-working position. The filter screen o

Mesh screen changer for plastic production line

Application area of screen changer It is used for melt filter screen changer in plastics, rubber, chemical fiber and ceramics extrusion production line. These switchers - from low-cost manual switchers to highly complex non-stop voltage regulated automatic switchers, are suitable for extruders with screw diameters of 35 mm to 300 mm. The net changer is often used in the following production lines: 1. from plastic resin synthesis reaction device to bulk granular extrusion granulating production l

The structure of the screen changer and the choice of control system

Structure of screen changer In order to ensure the filtering effect, the screen changer is generally composed of three parts: support plate (shunt plate), auxiliary plate and filter screen, and the filter screen is generally made of metal woven mesh. But sometimes for special needs, silk screen and sand filtration are used as polyester. Nylon is coated with sand to remove gel and impurities. In order to increase filtering face and improve filtering capacity, plug-in filters have been developed b
