PET Shredder - Polyethylene Terephthalate Size Reduction

A PET shredder can offer the ideal solution to the initial size reduction of post-consumer PET. With applications ranging from packaging and automotive parts to electronics and fabrics; PET has wide and varied uses across the market.

As one of the most commonly recycled polymers, PET has a number of advantageous properties that make it suitable for many consumer products, as well as being relatively simple to recycle. In order to achieve high-profit margins when it comes to PET, the end granulate produced should be of the highest possible quality.

One of the primary ways to ensure that the material is washed, dried, separated, and granulated to the best standard, is to process the infeed through a PET shredder towards the beginning of the recycling line.

By performing an initial size reduction of the infeed, the PET shredder reduces the surface area of the material; thereby preparing it for consistent and accurate processing later on in the recycling line. 

The final size reduction of the material can then be carried out later in the process by a PET granulator; making the material easy to store and transport.  

Due to the varied and far-reaching applications of PET, the material can often be heavily contaminated with various residues from its waste stream, including; plastics, glass, and metals, among others. Whilst Zerma shredders have been designed to manage almost any material and contaminant, regulating the flow of infeed into the PET shredder can be a necessary step to ensuring that the shredder doesn’t become overwhelmed with materials.

Using a feed hopper to discharge infeed at a steady rate can help to avoid bridging and blockages whilst also reducing the level of wear caused to the shredder blades. In addition to size reduction machinery, Rotajet also offers a full range of PET recycling equipment from washing and drying through to separation and bagging off, which can be fully integrated with your PET shredder.

With various options available to meet almost any throughput rate and cleaning requirement, we design and manufacture purpose-built machinery that is suitable for almost any application in the industry. No matter your specific operational requirements, get in touch with a member of our team today to discuss your PET recycling options or visit our dedicated webpage for more information on our full recycling lines.

PP Shredder - Polypropylene Size Reduction

The PP shredder plays a vital role in the size reduction of post-consumer and post-industrial PP. Processing infeed through a PP shredder means that the material can be easily managed in the next stages of recycling. As even-sized shreds with a smaller surface area, the PP can be accurately washed, dried, and granulated, to allow for consistent and high quality of out-feed.

A PP shredder is also a necessary stage in increasing the bulk density of the material, thereby making it easier to store and transport. With a wide range of advantageous properties, polypropylene is used widely across industries; for everything from automotive and pharmaceutical to food and textiles applications.

Due to its wide-reaching uses across the industries, post-consumer PP is generally heavily contaminated with everything from various plastics to food waste and oils. Designed to handle this level of contamination, Zerma shredders come fully equipped with a low speed, high torque rotor and four-sided cutting teeth that can process almost any infeed material.

Contaminants can then be accurately removed using separation equipment such as a sink float tank and zigzag separator. By regulating the flow of infeed through a feed hopper, materials can be fed to the PP shredder in a manageable and consistent way, whilst reducing the rate at which the blades become worn.

Its important to keep in mind that PP shredder blades need regular maintenance in order to stay in an optimized condition. With various factors from contaminants to infeed blockages effecting the performance of shredder blades, it is necessary to regularly check for signs of wear and clean them of any residues.

To get the best out of your shredder blades, Rotajet offers a range of spares and service contracts that can keep your operation working to its full potential. With regular site visits and actionable reports, you can have confidence that your equipment is repeatedly delivering the highest quality of outfeed.

Rotajet also offers a full range of recycling machinery that can turn your PP shredder into a fully integrated and automated PP recycling line. Managing the entire process from start to finish, our full plants have been designed to reduce labour, whilst delivering a high quality of PP granulate ready for resale.

PE Shredder - Polyethylene Size Reduction

A PE Shredder offers the ideal solution to the size reduction of post-industrial and post-consumer Polyethylene. Bypassing the material through a PE shredder, infeed can be reduced to even-sized shreds to allow for a consistent, all-round clean in the plastic washing stages before the further reduction in a plastic granulator. Material can also be dried and separated more accurately, leading to overall high quality of out-feed.

A Polyethylene shredder can also make the material easier to process in the next stages of recycling by reducing the air density in the material. This means that the infeed is reduced to small, manageable shreds that can be easily passed through each machine.  On top of this, the higher bulk density of the material means that it can be stored and transported much more easily.  

PE film often represents a challenge when it comes to plastic recycling – particularly during the size reduction stages. Due to the large surface area and high tensile structure of PE, the material is prone to causing build-up and blockages within machinery; resulting in machine downtime and operational costs.

Zerma’s series of ZSS, ZPS, and ZIS all-rounder shredders have been purpose-built with these complexities in mind, to offer the most fine-tuned solution to shredding PE products, such as; plastic films, bags, and packaging.

Post-industrial and post-consumer PE is commonly highly contaminated with everything from foodstuffs through to oils and dirt. Zerma shredders have been designed to manage these contaminants, with four-sided cutting teeth and a low speed, high torque motor that can process material in almost any application.

Due to the complex nature of PE recycling, the material has historically not been able to reach its full potential in the market; despite being one of the most commonly used polymers. However, with our purpose-built machinery and top-of-the-range Zerma shredders, PE can be managed in a way that is not only simple but highly profitable as well.

In addition to our range of size reduction equipment, we offer a full portfolio of machinery that can handle your entire PE recycling process from start to finish. From washing and drying machinery all the way up to full PE recycling plants, we manufacture recycling solutions that are built for purpose and suit your specific needs.

PVC Shredder - Polyvinyl Chloride Size Reduction

A PVC shredder can provide the ideal solution to the initial size reduction of post-industrial and post-consumer PVC. Unique for its dense, hard, and durable structure, PVC offers its own complexities when it comes to recycling. For this reason, PVC often goes widely unrecycled despite being the world’s third most produced plastic polymer and therefore offers a great deal of opportunity in the market.

With a built for purpose Zerma PVC shredder, PVC can be reduced to manageable shreds that can be accurately and easily processed in the later stages of the recycling line.

Due to the smaller surface area of the material, the shredded PVC can be cleaned, dried, and separated to a consistent standard, thereby resulting in a higher quality of product. 

Considering the unique properties of PVC, the PVC shredder is built with a high torque, low speed motor and four-sided cutting teeth that can process almost any infeed and its contaminants. 

Often highly contaminated with a wide variety of materials from its waste stream, PVC is generally mixed in with various metals, rubbers, foams, and glass that need to be removed from the infeed.

Once size reduced in the PVC shredder, these contaminants can be accurately removed in a sink float tank. For further size reduction, the PVC can be processed in a PVC granulator to turn the material into a pellet ready for resale, storage, and transportation.

In addition to the full range of Zerma size reduction equipment, Rotajet also offers a full portfolio of recycling machinery to manage the entire process from start to finish.

Including everything from washing and drying right through to fully integrated recycling plants, Rotajet can provide the right solution for almost any PET recycling application.
