When densifying certain materials, gravity can fall short of what’s needed to feed low-density bulk plastics into the equipment. That’s why Herbold Meckesheim USA has developed a force-feed mechanism for its line of HV Plastcompactor Densifiers.
“While traditional gravity feeding is appropriate in some cases, it is not ideal for materials like carpet fiber, film or polystyrene,” according to a company press release. “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.” PE PP pelletizer machine
Plastcompactor Densifiers are use to convert low-density bulk plastics into agglomerates with good flow characteristics and high bulk densities. Doing this with sensitive thermoplastics requires gentle processing.
With the Plastcompactor Densifiers, material processing takes place between rotating and fixed compaction discs, both of which are equipped with screw-mounted, replaceable kneading rails. Granulated material moves through the center of the fixed disc into the processing chamber, where it is rapidly heated by the two discs. The material is heated and dried, but thermal decomposition is minimized because the plastic remains between the heated plates for only a short time.
In contrast to standard batch-type agglomerators or compactors, the HV agglomerators carry out a continuous process without adding water to the product, according to the company.
Herbold makes its HV Plastcompactors in three sizes, depending on the throughput that’s needed. The throughput also depends on the source materials. As examples, the largest machine, the HV 70, can process up to 3,000 pounds per hour of polyethylene film, 2,600 pounds per hour of hard PS foam or 2,200 pounds per hour of PA 6 or PA 6,6 fibers, according to a product line brochure.

Plastics policy development – at both the global and state levels – drew readers last month, along with a major packaging firm’s acknowledgement it will miss its target deadline for recycling goals.
Closed Loop Partners has provided funding to more than 80 companies and municipalities over its decade in existence, a period of significant turbulence in the U.S. recycling sector.
The U.S. Plastics Pact this week unveiled the goals its signatories will strive for during the next five years. Most of the goals build on the efforts over the past five years, and the group’s target date to hit 30% average recycled content has been extended from 2025 to 2030.
Collaboration between all parts of the plastic value chain is necessary to advance sustainability goals, and four companies at the 2024 Plastics Recycling Conference showed how they’re embodying that idea.
Color HDPE dropped 10% in value this month, while other plastic grades remained steady or saw slight increases.
2023 was a record-breaking collection year for Canadian ag recycling nonprofit Cleanfarms.
French manufacturer Bic used 62% recycled content in its plastic packaging last year, moving it closer to a 2025 goal. But the company has a ways to go to meet its goal for recycled content in its actual products, which include lighters, pens, razors and other consumer goods.
