In the process of recycling and regenerating plastics, filtration is a fundamental step: it allows impurities to be removed and high-quality granules to be obtained. Screenchangers are used to manage this phase, as they are essential devices for ensuring production continuity and efficiency.
Germanplast offers a range of automatic and semi-automatic screenchangers, designed to meet different production needs. But what is the difference between these two solutions and how do you choose the most suitable one?
What is a filter changer and what is it used for?
A filter changer is a system installed on the extruder that allows worn or clogged filter screens to be replaced without interrupting or excessively slowing down production. This allows for:
- Consistent plastic pellet quality.
- Protection of the extruder from impurities and contaminants.
- Greater production efficiency and less machine downtime.
Semi-automatic screenchanger
Semi-automatic models require operator intervention to replace the filter screen.
Features:
- Manual system with levers or mechanical controls.
- Requires machine shutdown during replacement.
- Greater direct control by the operator.
Advantages:
- Lower purchase costs.
- Simple construction and use.
- Ideal for small to medium-sized production or plants with non-continuous cycles.
Fully automatic screenchangers
Automatic screenchangers allow the mesh to be replaced without stopping production, ensuring process continuity.
Features:
- Automatic system with hydraulic or motorised control.
- No machine downtime: replacement takes place during processing.
- Can be integrated with electronic control systems.
Advantages:
- Increased productivity: no interruption to the cycle.
- Better granule quality thanks to constant filtration.
- Less intervention required by personnel.
- Ideal for large-scale production and high-efficiency plants.
Which one should you choose for your plant?
Semi-automatic: perfect for those looking for a lower initial investment and who do not need a continuous production cycle.
Automatic: the right choice for those who want to maximise productivity, reduce machine downtime and work on large volumes.
