Product Description
Our PE film washing line uses a wet plastic granulator to cut large pieces of PP / PE film into small, uniform shreds sized between 12-18mm. Our plastic granulator has the unique ability to cut plastic film quickly and efficiently using fast spinning open rotor mounted with heavy-duty knives in a double-scissor cut array. As the plastic film enter the granulator’s cutting chamber, the rotor knives come into contact with stationary knives effective cutting the film in a continuous fashion.
The size of the PE film shreds are controlled by a screen filter with holes that is mounted underneath the cutting chamber. The plastic film is held within the cutting chamber until it reaches the desired size and falls through this screen filter. Usually speaking, our standard screen filter hole size is 15mm.
To ensure reliability and dulling in the most demanding situations, all knives used in our granulator is made from high quality D2 high-carbon, high-chromium steel (equivalent to SDK11 steel). For the sake of usability, all 12 rotor knives and 3 stationary knives can be easily adjusted with hydraulic assisted access to the cutting chamber.
To further benefit from our already robust structural design, our PE film washing lines use a wet granulation process where water is sprayed into the cutting chamber via nozzles. This not only partially cleans the PP/PE films, it also adds a layer of lubrication to reduce friction and heat during long operations. Based on our testing and experimentation, our wet granulators require 2-3 times less knife sharpening compared to dry granulating.

For whole bales or bulky feedstock ahead of the granulator, our double-shaft shredder pre-cuts material to a size the granulator can handle efficiently.

Frequently Asked Questions
How does a wet plastic granulator work?
A fast-spinning open rotor mounted with heavy-duty knives in a double-scissor cut array rotates against stationary knives, cutting film continuously. Material stays in the cutting chamber until it is small enough to fall through the screen filter mounted underneath — producing uniform 12–18 mm shreds, with a standard 15 mm screen hole size.
What is wet granulation and why use it?
In wet granulation, water is sprayed into the cutting chamber via nozzles during cutting. This partially cleans the PP/PE films as they are cut and adds a layer of lubrication that reduces friction and heat during long operations. Based on testing, wet granulators require 2–3 times less knife sharpening than dry granulating.
What materials can the granulator process?
It cuts large pieces of PP/PE film into small, uniform shreds for the PE film washing line. The fast double-scissor cutting action handles film quickly and efficiently, delivering consistent 12–18 mm shreds that wash and separate evenly in downstream stages.
What models and capacities are available?
The standard range runs from the SWP630-1000 (630 mm rotor, 1000 kg/h, 55 KW) through the SWP700 series up to the SWP800-1200 (800 mm rotor, 1200 mm knife width, 2500 kg/h, 90 KW), all running at 470 rpm. Larger, more powerful granulators are available on request.
What are the granulator knives made of?
All knives use high-quality D2 high-carbon, high-chromium steel (equivalent to SKD11 steel) to resist dulling in demanding wet conditions. The 12 rotor knives and 3 stationary knives are easily adjusted via hydraulic assisted access to the cutting chamber, making service and knife changes straightforward.
What are the lead times for ordering?
The lead time for a single piece of equipment is 30 days from the signing of the purchase contract. For custom orders such as complete washing lines, the lead time is between 60–90 days. Actual lead times depend on the project’s complexity and factory availability.
