Product Description
Single-plate Hydraulic Screen Changer
FLEXIBILITY, ERGONOMICS, QUALITY: A PRODUCT SUITABLE FOR ANY PRODUCTION CHALLENGE, EVEN THE MOST DEMANDING.
AJK series screen changers are equipped with a pressure-adaptive sealing system as a standard. Thanks to this sealing system, the required sealing forces are adjusted to the actual melt pressure automatically. The narrow design is especially suited for being used in applications with thermally sensitive materials. Their solid and robust construction, available in all sizes and designs, ensures a reliable and leak-free filtration of molten polymers for many years. The hydraulically operated screen changer reliably guarantees the protection of melt pumps and mold gaps from damage and dirt.
Your benefits• Simple operation and uncomplicated screen changing• High operational reliability• Short material residence time• Leak-free mode of operation• Low pressure consumption• Flow channel geometry without any dead spotsOn the inlet side, the rheologically optimized flow channel directs the melt flow into the screen cavity, where the breaker plate is located. The molten plastic material flows through the breaker plate which is equipped with screen mesh selected according to the required filtration rate. Downstream of the screen, the cleaned melt stream leaves the filter housing through the flow channel.
To change the screen, the breaker plate is moved out of the housing and at the same time, the clean screen on the outside is moved into the production position. When using a hydraulic accumulator, the changeover takes only a fraction of a second. The melt flow will be interrupted during the traversing time of the slide plate.
Features:• Designed for high production or recycling extrusion lines, due to ongoing technical development, have reached a high degree of ergonomics.• The high reliability and durability testify to the quality of this product, which meets the diverse needs, with excellent results even in the most difficult and challenging situations.• Available with filtering areas from Ø 70 to Ø 400 mm. units are equipped with a new protection system which allows better access to the sliding plate during screen replacement, and a new wiring system that allows rapid intervention in case of maintenance.• With highly precise design, the screen has good abrasive resistance, good durability under high pressure, ensuring large effective filtration area and improving filtration performance.• It works well even under high temperature up to 300 ºC and high pressure up to 50 MPa.• Screen changing process completed in a period ≤ 2 seconds with pressure accumulator.Accessories

FAQ
What is screen changer?
Screen changer includes one or more filter devices. When the polymer fluid flow enters the filter device, the contaminants in the melt is blocked in one side of the filter. The filter is supported by a breaker plate, while the breaker plates are installed in the support carriage; support carriage parts can move, stay in the work place or non-working position.
Screen changer is available supporting the device as following: extruder, melt pump, reactor or other extrusion lines. It can be used to filter any type of polymer and thermoplastic.
Why you need melt filtration device?
As quality specifications become tighter and the need to use more recycled materials becomes more prominent, more and more extrusion processors are examining their options in melt-filtration technology. There are three basic reasons why you need melt filtration:
1. Product quality specifications mandate visual or mechanical properties that cannot be maintained without filtration.
2. Downstream equipment may become damaged by contaminants in the melt.
3. Additional melt pressure is needed to improve melt quality.
It is likely that most extrusion processors will fit into one of the above categories, and that they will find a simple breaker plate unsatisfactory due to the time required disassembling and reassembling the device. The alternatives considered here are various types of screen changers, though other types of filters may be used for special purposes, like high output rates and very tight filtration requirements.
Common uses for screen changers are:
Bulk polymer production from a reactor i.e. producing pellets.
Extrusion lines for compounding polymers, blown film, cast film, sheet, pipes, profiles, plastics recycling.
Different types of Screen Changers are available, to cater for different applications and process requirements. Manual type or slow speed screen changers require the production line to be stopped for a short time to enable the filter to be changed, other types, operating at high speed, can change filter without stopping or slowing down the extrusion process.
For the production of blow film, sheet, pipes, etc, continuous flow screen changers are the most suitable type as the melt continues to flow during a screen change.
Each type of Screen Changer is available in different sizes, to cater for different output requirements. Anji Screen Changers are available from 30mm diameter for polymer outputs of 100 kg/h to the massive Extended Area for outputs up to 60,000 kg/h. For new or existing lines, Anji can design and manufacture adaptors, which may be required to connect the Screen Changer to the rest of the line.
How to choose a suitable screen changer?
As for screen changer, we need to be told as follow:
1. What is the processed material, PP/PE/ABS/PET? Is it new material or reclaim material?
2. Is the extruder single screw or twin screw? What size is the screw diameter?
3. Production capacity (Kg/h)? Max operating pressure?
4. What is the finial products, plastic pipe or sheet, pellets?
5. Do you require continuous or discontinuous process?
According to the technical feedback, we will suggest that screen changer more suitable your processing requirement.
What are the benifits of screen changer on extruder?
1. Improve the quality of the final products
2. Greatly improve the plasticizing of the raw material
