Plate type continuous screen changer for foam plate extrusion mahcine
Overview
This kind of screen changer consists of the main body of the screen changer and four unique screen packs, and equipped with leading material- feed and exhaust system.
Before screen changing, it can lead to feed material, and the exhaust system begins to work, then the standby location screen pack move to the working position. The impurities and the air in the raw material then can be removed, thus reduce the scrap.
The whole screen changing time is a continuousness and stability process, the melt pressure without fluctuation.
This kind of screen changer help the extruder make a high performance
The working principle
This series of screen changer consists of four independent breaker plates, each with openings of same
Diameter and screen pattern. The rotation of these specially treated alloy metal plates gives superior
Sealing ability and durability. This type of screen changer has slight flow fluctuation during screen changing.
It can guarantee a continuous and stable extrusion production.
. Features
Breaker plates move in the same direction one by one, improved filtration performance,
Equipped with preheating and ventilation design to minimize the effect of possible
Temperature, pressure, melt flow fluctuation on final product during screen changing process.
Guaranteedno rupture on film and filament production, and changing the screen without stopping the production.
