Zhengzhou Anji (China) Plastic Machinery

Types of Screen Changer

The screen changer is a fundamental device because it filters the material coming out of the extruder before the granulation stage and guarantees the total purity and quality of the end product.
We provide back flush screen changers and continuous screen changers depending on the application, contamination, level of filtration required and customer preference.
The continuous improvement of product quality and the development of new sources of raw material demand high requirements in regard to melt filtration.

Anji’s melt filter was developed for the filtration of plastic melt with both a low as well as a high degree of contamination.

For melt filtration we offer one- and two piston screen changer. The filter diameter is available from 58 mm up to 360 mm. The screen changers are developed as continuous ones, so that a filter change can be done during running production without a production interruption. The pistons are equipped with a hydraulic unit to do the filter change.
The screen changers are developed in that way that integration in an existing line is possible. Appropriate adapter flanges make an adjustment possible to all usual extrusions.

Describe us your application and we will design a suitable screen changer.

Hydraulic Screen Changers:

The hydraulic Screen Changer is suitable for reprocess kind of extrusions like RP Plants, Filler and Master batch Plants, Compounding Plants etc…, where highly contaminated kind of materials are processed.

Features:
Our Screen Changers are very precisely made for guaranteed leakage frees Performance.
Comes with energy efficient and most power full Power Pack. By this Screen / Station change is possible within less than 3 seconds.
Once the Hydraulic system started, hole-to-hole screen changing can be quickly accomplished without wasting production.
Built-in Heaters gives fast heating and superior temperature retainment.
Ensures Quality processing, high product quality and reduced waste materials.
Our Screen Changers are very compact, Operator friendly & easy to install with Low Maintenance and low cost spare parts.
It is most reliable and durable, as it is made by a steel body for long life.

Manual Screen Changers:

The Manual Screen Changer is suitable for virtually any extrusion process that can afford a momentary shutdown to change screens and offers the most cost effective method of filtration available. We have two types of Manual Screen Changers:

Features:
Our manual Screen Changers was designed and precisely made using special Seals, insuring leak-free operation.
Built-in Heaters gives fast heating and superior temperature retainment.
Ensures Quality processing, high product quality and reduced waste materials.

Continuous Screen Changer:

Advantages :

Filters can be cleaned and replaced without stopping the plant. It gives guaranteed continuity in processing and maximum utilization of the plant.

More production because zero shut down for screen change. Production will Increase by Saving Production Hour. (We can save minimum 1 Hour/day on a/c of Screen changing.)
Very less Wastage (as good as zero) while Screen Changing. Save Money on Wastage of Raw Material by up to 20 kg/day during Screen Changing, Plant Start-up, Plant Shut-down etc… Normally, in today’s competitive environment, processors are using 10 – 40 % Filler (Caco3) and in such condition, Frequency of Screen/Filter changing is approx 40 – 50 times in a Month. Means lose of 1000kg. Of material per month.
Save Power of up to 60 Hours/month on a/c of Heat Loss during Screen Changing, Plant Start-up, Plant Shut-down etc… Normally, in today’s competitive environment, processors are using 10 – 40 % Filler (Caco3) and in such condition, Frequency of Screen/Filter changing is approx 40 – 50 times in a Month.
