General Description

In post-consumer or post-industrial plastic wastes, like LDPE, LLDPE, HDPE, PP, CPP, BOPP, PS, EPS, XPS, ABS, POM, PA etc, many contamination type can be found such as iron/steel, wood, paper, textile fibers, Un-melted plastics, aluminium, sand, copper, stones, almost others. By the contaminates are constantly increasing and the traditional (manual) screen changers are not able to deliver a good quality of the final product. For this reason, it is necessary to switch to an automatic and continuous system.

Kitech Laser Filter is the most suitable filter to recycle contaminated plastics. It filters high levels of contaminates and can resist high pressures. The operator can therefore dedicate more time to an efficient feeding of the extruder, and does not to have to change filter screens before the pressure reaches the set point. It reduces the operational and labour costs. The Laser filter adapts to your material: depending on the MFI (from 0,124 to 200 g/10’). It improves your quality results and any level of filtration fineness is available, from 150 to 850 micron (100 to 20 mesh).

Application
Structure
The laser Filter is composed of a reducer, front and back filter chambers, scraper, filter screen plate, discharge screw, etc.

Laser sieve disk:The circular shape of the disc screen holes enables a constant quality of the material during the whole process.
Disc screens are not made with wire mesh but a solid metal with punched or laser holes. so the holes do not enlarge with pressure, Filtration 150/200/250/300 /400/500 micron.
Two screens normally allow min. three months operation (in consideration of 4 times cleaning in vacuum cleaning oven)

Scrape blades: The Scrape blades are installed on scraper base, 6pcs/set(3 blades are required at every disc screen), made by DC53 hard alloy, Sharpened either on front or back side (depending on contamination type).
Advantage

1. Non wire-mesh required, long using life of disc screen plate.

2. Reliable continuous filtration with stable pressure, realize non-stop production, improve the production efficiency.

3. Double screen design with high throughput.

4. Reduce the operational costs to less than half, thanks to the screens( either punched or laser) as well as scraping blades.

5. Automatically wiping action to assure constant self-cleaning of screen plate.

6. Replace the disc screen easily.

7. It can resist high pressures more than 30mpa.
