Dual Piston Hydraulic Non Stop Screen Changer
The double-column hydraulic non-stop screen changer is a core continuous filtration device specially designed for polymer extrusion production lines, widely applied in plastic granulation, film blowing, pipe extrusion, and recycled material processing industries. As a upgraded alternative to traditional single-station screen changers, it solves the pain points of production shutdowns, low efficiency and unstable product quality caused by frequent screen replacement, becoming an essential equipment for high-volume and high-stability extrusion production.
This screen changer adopts a dual-column and dual-station alternating working structure, equipped with an independent hydraulic drive system and sealed filtering channels. Its core working principle is simple and efficient: during continuous production, two filter columns operate in standby and working states alternately. When the filter screen of one column is blocked by impurities and needs replacement, the hydraulic system automatically switches the material flow to the other standby column. The screen replacement process is completed instantly without interrupting melt flow or halting the production line, realizing truly non-stop screen changing operation.
Featuring stable pressure output, precise hydraulic control and excellent sealing performance, the equipment effectively avoids melt leakage and pressure fluctuation during screen replacement. It supports long-term operation under high temperature and high pressure conditions, with strong adaptability to various polymer materials and impurity contents, especially suitable for recycled plastic extrusion with high impurity rates. Compared with ordinary screen changers, it greatly improves production efficiency, reduces material waste and labor costs, and ensures consistent finished product precision.
In modern extrusion industrial production, automated and continuous processing has become the mainstream trend. The double-column hydraulic non-stop screen changer perfectly matches intelligent production needs, helping enterprises reduce downtime loss, optimize production processes and improve overall economic benefits. It has become the preferred filtration equipment for medium and large-sized extrusion production lines worldwide.
