HOT WASH SYSTEM FOR RECYCLING POLYOLEFINS

Drawing from its vast assortment of proven plastics recycling equipment, Herbold can custom configure Wash Plants for polyolefins capable of producing high-quality, food grade recyclates.

While each wash plant is designed around the user’s specific requirements and facility characteristics, all feature a multi-stage process usually consisting of pre-shredding, pre-washing / initial separation, granulation, high density separation, and drying.

Pre-shredding is typically done in a single-shaft shredder such as the Herbold 60/120. With a 23.5” diameter rotor and 60 individual knives, these rugged machines can accept entire bales of contaminated waste and process up to 13,000 lbs. per hour.

Washing takes place in a VWE-60 pre-washing unit which employees a 3-step process of sink/swim to remove heavy materials, intensive spray wash to loosen and remove embedded sediment and an additional sink/swim to further eliminate remaining sediment.

Further size reduction takes place in a wet granulator such as the Herbold 80/120. The wet operation provides additional separation of particles and contaminants from materials.

Additional high-density separation of contaminants and recyclate occurs in a Hydrocyclone. The extreme centrifugal force of the Hydrocylcone provides separation that exceeds conventional methods by a factor of 15 ensuring the level of purity necessary for food grade recyclate.

After final separation, materials are conveyed to either a mechanical or thermal dryer for removal of residual moisture prior to use or storage.

Five times more flakes from recycled PET bottles

Herbold Meckesheim GmbH obtained a new major order in December: it will supply a largescale plant for plastic recycling to Fantastic Plastic. Fantastic Plastic is considered to be the producer of the highest quality PET flakes in Russia. The first production line of the recyclate manufacturer was also supplied by the Meckesheim-based special machinery manufacturer Herbold.

In 2019, Fantastic Plastic's plant in Nizhny Novgorod, Russia, went into operation. Since then, together with Herbold Meckesheim and the downstream manufacturers, elaborate trials have been conducted to refine the process. The goal that has now been achieved is that the quality of the granules meets the strict regulations for food packaging and can be used bottle-to-bottle.

The fact that Herbold maintains a technical center at its headquarters in Meckesheim, which can be used for trials of all kinds, was of great benefit here.

Thanks to closely coordinated planning – the project is now starting in January – periods of downtime in main production are largely avoided during the installation of the machines. Fantastic Plastic aims to use the new recycling line to boost its granulate output to 35,000 metric tons per year, a fivefold increase. The Russian company has invested a good 10 million dollars in this project. It is expected to create around 180 new jobs at the site.

The recycling company INVEMA (www.invemagroup.com) commissioned a plant for the recycling of PET bottles in Honduras at the end of 2016 in order to produce bottle-to-bottle quality with FDA approval. In Honduras the collection rate of PET bottles amounts to 84 %. Today, 2000 tons of PET bottles per month are treated with the plant technology from Herbold Meckesheim, nevertheless, bottles have to be imported in order to use the plant to full capacity.

High regeneration quality

In a multi-stage process, the bottles are pre-sorted, size-reduced, washed cold and hot and after drying forwarded to a flake sorting step. After sorting, the PET bottles are size reduced with two Herbold granulators with a capacity of 1800 kg/h

The hot washing line for PET bottle flakes from Herbold Meckesheim guarantees a high regeneration quality at INVEMA. A secondary cleaning of the PO fraction is carried out in a hydrocyclone separation step. The plant was created in a second step for the treatment of the polyolefine fraction from the recycling process, i.e. the caps and labels of the bottles. A second expansion step is in preparation. Its aim is to produce Food Grade PET Pellets, produced from Herbold Washed Flakes.

Herbold Meckesheim is your specialist for granulators, shredders, pulverizers, plastcompactors (agglomerators) as well as for complete plants but also for single components for washing, separating and drying of contaminated plastics.

of HV Plastcompactor Densifiers used to agglomerate low bulk density material. The resulting agglomerate has a higher bulk density than the source material with improved flow characteristics.

While traditional gravity feeding is appropriate in some cases, it is not ideal for materials like carpet fiber, film or polystyrene.
The new force feeder mechanism uses an auger to convey material at a higher and more consistent feed rate to deliver increased throughput and reduced energy consumption.

Continuous material processing takes place between a rotating and a fixed compaction disc. Both discs are equipped with screw mounted, replaceable kneading rails. Pre-granulated material moves through the center of the fixed disc into the processing chamber where it is rapidly heated by the two discs.

Three sizes of HV Plastcompactors are available offering throughputs as high as 2,600 – 3,000 lbs. per hour.

SMITHFIELD, RI — Herbold USA has announced the availability of a new force fed granulator for size reduction of PET bottles. The Model SMS 100/160-9-2 SB3 features a rotor that is 20% larger than current offerings. The additional size and mass of the rotor allows the granulator to operate at higher throughput rates (up to 7 tons per hour).

Material is fed into the destruction chamber via a screw fed mechanism that utilizes 3 vertically mounted feeding screws. This feeding method offers several advantages over gravity feeding including consistent, even feed rates, reduced power consumption, no material flyback, quieter operation, less wear on the cutting chamber, and reduced fines and dust.

The unique knife geometry which positions inclined rotor and stator knives at the same, but opposing angles provides a true double cross cutting action.

SMITHFIELD, RI — For plastic recycling plants, the Herbold Meckesheim Label Remover is more effective than any other machinery for the removal of wraparound polyvinyl chloride (PVC) labels from polyester (PET) bottles.

Until now, removing and separating wraparound labels has been impossible at the prewash stages of bottle recycling and difficult and costly at subsequent stages, but the Label Remover is a game changer. Now, these tightly clinging labels can be removed in a single step, early in the process and without the expense of generating extra steam. The new machine also separates bottles that are stuck together, reducing labor costs for manual separation.

By removing almost all wraparound labels early in the recycling process, the Label Remover also saves money in another way: Down the line at the size-reduction stage, cutting blades will stay sharp longer because they won’t be dulled by many label remnants stuck to bottles.

The Label Remover is available with two different capacities — 4,500 or 8,000 kilograms per hour. Inside each machine, the removal of labels and adhesives from bottles is accomplished through friction between exchangeable rip-off elements bolted to the rotor and exchangeable pins fitted to stator elements. All rip-off elements and pins are made of special wear-resistant steel. The design of the chamber ensures even loads and dwell times as bottles are advanced by the rotor. The chamber has no spaces where bottles might pass through the machine without undergoing full frictional contact, and likewise there are no surfaces to constrict the bottle flow, reducing the possibility of damage to the bottle.

In the fracture-proof, welded-steel housing of the Label Remover are a hinged cover and additional service openings to ensure access when worn parts need replacement. The rotor’s dual self-aligning roller bearings are mounted outside the housing to minimize contamination. Anti-vibration mounting pads are standard.

Herbold Meckesheim USA, a subsidiary of Herbold Meckesheim Germany, designs, manufactures, and installs size-reduction equipment (shredders, granulators, etc.) and wash-line equipment (debalers, separation tanks, friction washers, dryers, compactors, etc.) for the plastics industry, specializing in the recycling of industrial and post-consumer plastics. Components of the company’s systems are designed as modular “building blocks” so that a system can be extended or modified according to the customer’s requirements. As plastics recycling becomes more complicated due to increasing volumes, more contamination, new sorting procedures, automation, newly accepted types of plastic, etc., Herbold anticipates the needs of all plastics recycling facilities, whether they are processing soda bottles or car bumpers.

The newly founded Stricker PolyRec Company has recently launched a large-scale plant for size-reducing, agglomerating and refining engineering plastics waste.

Especially such materials that need a particularly inoffensive treatment such as PET, PA and PC films, nonwovens, filaments, fibres and other plastics can be recycled with this plant in an economic way and without any or with only the slightest thermal degradation or IV drop.

The end product is an agglomerate with excellent flow properties and a high bulk density, free from fines by sifting and screening. The granule size of the end product can vary according to the customer’s specification. (Fig. 1)

Stricker PolyRec opted for the plastcompactor concept developed by HERBOLD MECKESHEIM GmbH since it best met the high quality requirements. Due to the short residence time and the special slight sintering process preventing the material from melting, voluminous materials with poor flowing properties can be turned into a 100 % reusable resource.

One example among many is the treatment of PET bottles transformed into clean but badly flowing flat flakes after washing, separation and drying. With the help of the plastcompacting procedure used by Stricker PolyRec, these flakes are not only turned into a material with excellent flow properties, appropriate for a trouble-free gravimetrical dosing for film production lines. In one production step, PET is at the same time completely crystallized.

The heart core of the new plant at Stricker PolyRec is the HERBOLD-Plastcompactor HV 70 with a 250 kW main drive as well as a fully automatic system control in order to guarantee an unchanging quality.

HERBOLD Meckesheim GmbH designed, developed and delivered this turn-key plant. Special emphasis was given to a universal application of the machine and a quick material change due to an easy access for cleaning. (Fig. 2; Fig. 3)

Egbert Schmidt, the managing director of Stricker PolyRec, was quoted as saying:
"HERBOLD MECKESHEIM presented a convincing concept with a good price-performance ratio. In close cooperation with the manufacturer we succeeded in developing the optimal plant configuration, so we are well prepared for forthcoming recycling problems in accordance with market requirements.”

Agglomeration is also a toll service Stricker PolyRec offers to companies wishing to reuse their plastic waste for their own production.

Their staff is highly experienced in the agglomeration of all kinds of plastics. The company started their production with this new plant at Schwerte-Westhofen, near Dortmund, in October.

When your motto is “Scrap everything you think you know about unusable plastic,” you had better be able to tackle the hard recycling jobs. Plastics recycler Butler-MacDonald Inc. (Indianapolis, IN) says recent machinery investments are helping it do just that. Last year, in fact, was the 65-employee-strong company’s most profitable in its 27-year history. Its customers include plastics compounders, telecommunications companies, and producers of CDs and DVDs, aeronautical and automotive parts, vinyl siding and windows, PET bottles, and pharmaceuticals. Some customers buy back the purified polymers from their own recycled waste.

“If something plastic-based is hard to recycle, that’s where we come in,” says J. Scott Johnson, Butler-MacDonald’s president, CEO, and chief system designer. “If something is easy to recycle, people don’t usually think of us.  

Butler-MacDonald's new SMS 80/120 granulator from Herbold
Meckesheim has helped it increase itsavailable capacity and drop
its labor costs.

But that, too, is changing. As people do more and more recycling, digging deeper into the pile, if you will, they’re ending up with more difficult things to recycle. So that’s where some of our growth has come from—difficult work is our forte.”

For example, a company that sells thermoplastic olefins had an 80,000-lb batch rejected by its customer because it was contaminated with nylon and thermoplastic polyurethane (TPU). Butler-MacDonald showed that the nylon and TPU could be removed economically. It saved the client from a damaged reputation and a significant loss by delivering a 91% yield of TPO at a purity level acceptable to the client’s customer at the original sale price. The client kept its customer and still made a profit on the batch.

When Johnson saw that his company’s increasing business was going to require another large granulator, he spent more than a year shopping for a new one. “We put things in a granulator that other folks don’t want to put in a granulator,” he explains. “Because we are trying to take plastic recycling to new levels, we’ve made sort of a science out of understanding how granulators work.” He settled on an SMS 80/120 granulator from Herbold Meckesheim Gmbh, which designs, manufactures, and installs size-reduction equipment and wash line systems for the plastics industry, specializing in equipment for the recycling of industrial and post-consumer plastics.

The German manufacturer was not well represented in the U.S. Midwest until 2007, when Dave Cortner of Jeda Equipment Services in Indianapolis picked up regional representation of the Herbold product line. Cortner arranged meetings for Johnson first with David LeFrancois, head of Herbold’s North American operations, and then also with Karlheinz Herbold, co-owner of the company. Herbold had his company design the new granulator to Johnson’s specifications, which included adding a special metal-detecting feed conveyor, and at a price tag that reportedly was lower than domestic manufacturers. Installation was completed in mid-2008. The new unit’s fast evacuation of granulated plastic helps output of 8500-9000 lb/hr, higher than another similarly sized granulator already installed at the facility. Johnson says, “We base our pricing on hours, so our labor cost has dropped to about 60% of what it used to be, across the board. And now we have time to take on more business.”

The rotor and bed knives of the SMS 80/120 reportedly can be removed easily and adjusted quickly in a fixture outside the granulator. Interchangeable screens are available to help control the size of particles coming out of the granulator. And whereas an older granulator in the Butler-MacDonald plant requires up to four knife changes (and sharpening of the knives) per week when running near capacity and processing abrasive materials—which can translate to as much as 800 hours of downtime per year—the new unit’s knives are made of a more durable alloy and are ground at a different angle, so that they usually require only one change per week, for an annual total of about 200 hours of downtime.

The recession also has hit his firm, and Johnson says he cannot expect 2009 to be another record year; indeed, the company has had to fire some of its customers for nonpayment. However, new markets are developing, due in part to the recession-induced shutdown of some Chinese facilities to which some U.S. producers used to sell plastics waste.

Butler-MacDonald uses its new equipment to recover
plastic from various mixed-waste streams, including
this post-production scrap from a window manufacturing
plant.
