Yuzhuo Machinery: Solving Tangling and Jamming Bottlenecks for Complex Solid Waste

Shredding and crushing serve as the critical first step in transforming solid waste into recycled resources. However, recycling companies frequently face severe bottlenecks when dealing with bulky, heavy plastic purgings and highly unpredictable industrial waste.

Materials often wrap around the cutter shaft, causing frequent downtime. Furthermore, oversized, rigid materials resist feeding, leading to rapid tool wear. These erratic, interrupted operations directly drag down the throughput and profitability of the entire recycling line.

While many machines can easily handle uniform materials, they routinely fail under real-world operating conditions characterized by mixed, chaotic, easily tangled, and ultra-hard waste.

Engineered from the Core

Many shredders on the market fail frequently, and the root cause usually comes down to flawed blade design, inadequate overload protection, and sub-par tool materials.

What sets Yuzhuo Machinery apart is the company’s dual capability: it handles both in-house blade manufacturing and complete machine design. Instead of simply assembling off-the-shelf parts, it optimizes the equipment from the cutter head up. This allows the company to directly solve real-world site issues like tangling, jamming, and the difficulty of crushing hard materials.

To solve the severe tangling issues caused by filaments and films, Yuzhuo Machinery’s self-developed, patented serrated blades are paired with a counter-helical structure. Operating at low speeds with high torque, this system shears through materials efficiently to eliminate tangling risks at the source. It is also equipped with a smart overload protection system; when encountering severe wrapping or rigid blockages, the machine automatically reverses and triggers an alarm, self-correcting within a short time to drastically reduce downtime.

When handling massive, high-hardness plastic purgings, the equipment utilizes current sensors to dynamically adjust its output torque, automatically boosting power the moment it hits exceptionally hard objects. This allows oversized materials to be fed directly without any pre-cutting, effectively extending the lifespan of the cutting tools.

Leveraging the localized tooling industry advantages, Yuzhuo Machinery offers highly wear-resistant blade materials such as Cr12MoV and SKD-11 to balance powerful crushing capabilities with low long-term operational costs. At the same time, the company supports non-standard custom engineering to adapt to diverse and complex working conditions, including plastics, chemical fibers, agricultural films, bulky waste, and hazardous materials.

Unlike generic equipment manufacturers, Yuzhuo Machinery can custom-match blade profiles, screen meshes, and torque parameters based on the specific characteristics of our clients' incoming waste. The company truly achieves the goal of delivering "machines customized for the material," ensuring that clients never have to force their waste streams to fit a standardized machine.

From Rigid Plastics to Tire Cord

The field performance of Yuzhuo Machinery’s equipment has been proven across numerous operational recycling lines. The following three projects showcase how the company’s customized shredding equipment solves three classic industrial bottlenecks: rigid plastics, high-tenacity tangling fibers, and municipal waste bag-ripping.

1.PC Materials

Bulk PC (polycarbonate) purgings are inherently pure, high-value, rigid waste materials generated during PC extrusion or injection molding. Sourced primarily from companies extruding PC boards, sheets, profiles, and pipes, as well as PC modification and compounding facilities, these materials are exceptionally hard, tough, and bulky. Shredding them has long been an industry pain point.

A plastics modification company in Qingdao previously relied on hydraulic shears to cut these massive purgings into smaller pieces before feeding them into a granulator. This process was highly hazardous, as flying debris during shearing could injure workers, and the overall efficiency was painfully low while putting excessive stress on the granulator. After integrating shredders from Yuzhuo Machinery, their processing efficiency increased significantly, and workplace safety was completely secured.

2.Tire Cord Fabrics

An enterprise in Guizhou was struggling with one of the most notoriously difficult materials in the recycling sector: waste tire cord fabrics. Tire cords possess extreme toughness, tear resistance, and tensile strength, while the remaining rubber is highly elastic and stretches under compression. During shredding, this combination easily wraps around the main shaft and cutting tools, making output size difficult to control and rendering the material impossible to feed directly into a pulverizer or granulator.

To address these material characteristics, Yuzhuo Machinery deployed proprietary anti-tangling cutters paired with a customized Model 1000 single-shaft shredder. The company linked this with an infeed belt conveyor, a Model 800 granulator, and an air separation system to build a complete processing line.

The anti-tangling design minimizes fiber wrapping at the source, while the granulator and air separator precisely control output size and purity. Delivering a throughput of up to 500 kg per hour, the system perfectly satisfies the client's pre-granulation requirements and earned their highest praise.

3.MSW Bag Ripping

A smart technology enterprise in Zhejiang focuses on municipal solid waste (MSW) sorting. MSW is typically collected and processed in bags; tearing these open manually is not only highly labor-intensive but also poses significant risks to workers' physical and mental health.

To meet the demands of MSW sorting, Yuzhuo Machinery utilized a detachable cutter head design. Through the ingenious interplay of the cutter tips, tools, counter knives, and rotary blades, the company achieved a "rip the bag, spare the waste" solution. The machine tears open the trash bags without damaging the recyclable items inside, making it much easier for downstream systems to sort out valuable target materials.

Equipped with the Model 1400 dual-shaft bag ripper, the system achieves a throughput of over 14.5 tons per hour. It efficiently replaces manual bag ripping and ensures a stable, continuous feed for the subsequent sorting line.

From Standalone Equipment to Customized Solutions

Rooted in Bowang, Ma'anshan, and backed by a comprehensive machining infrastructure, Yuzhuo Machinery boasts a complete product matrix that includes single-shaft, dual-shaft, and four-shaft shredders, integrated shredder-granulators, and film crushers.

Yuzhuo Machinery provides both standardized standalone machines and non-standard custom engineering for entire crushing sections. The company’s business spans numerous sectors, including plastics recycling, chemical fiber recovery, agricultural film processing, bulky waste management, industrial hazardous waste, and RDF preparation.

Exploring Breakthroughs in Solid Waste Pre-Treatment

To achieve high-value recycling of solid waste, the stability and reliability of the initial shredding and crushing stage are absolutely critical to the efficiency of the entire downstream process.

From November 25 to 27, 2026, Yuzhuo Machinery will showcase its comprehensive lineup of shredding and crushing equipment, along with its customized solid waste pre-treatment solutions, at the Suzhou International Expo Center. Together, the industry can explore equipment selection and production line optimization strategies.

Let us gather at the CRRE expo to bridge the entire chain—from crushing and sorting to high-value regeneration—and unlock the true circular value of solid waste resources.
