Recently, the production workshop of Zongheng Machinery has reached a key milestone of mass delivery. The new generation high-efficiency screw squeezer, independently developed, iterated and fully upgraded by the company, has successfully passed standardized performance tests under all working conditions including precision complete machine assembly, no-load commissioning and material-carrying trial operation, with all core indicators meeting standards, and has officially rolled off the production line in batches.
This batch of brand-new squeezing equipment has undergone strict factory inspection and process verification. Compared with traditional models, it achieves all-round upgrades in operational stability, dewatering precision and energy efficiency. The equipment will be delivered to many major domestic partners engaged in plastic recycling, agricultural film recovery and chemical fiber waste treatment one after another, and put into core processes of renewable resource washing production lines.
The successful mass production and delivery of the new model marks that Zongheng Machinery has reached new heights in intelligent manufacturing capacity, core technology R&D strength and product iteration innovation in the field of solid-liquid separation and dewatering equipment. It provides high-performance and highly reliable core equipment support for the green and low-carbon transformation of China’s waste resource recycling industry.
In the waste plastic recycling industry, the screw squeezer serves as the core dewatering equipment for cleaning lines of soft and lightweight materials, including plastic films, ton bags, woven bags and chemical fiber fabrics. Its operating stability and dewatering performance directly determine the finished product quality, production capacity and overall operating cost of the entire recycling line, making it an indispensable key device for plastic resource utilization.
Traditional screw squeezing equipment features outdated structural design and prominent industry pain points, including uneven dewatering effect, high final moisture content, poor wear resistance of extrusion screws, easy deformation after long-term operation and high overall energy consumption. It is also prone to material winding, blocking and jamming when processing thin and soft materials.
In addition, conventional equipment has low integration and complicated disassembly and maintenance procedures. Frequent downtime seriously restricts continuous and large-scale production, and can no longer meet the automated, standardized and high-efficiency production demands of the modern renewable resource industry, creating an urgent market demand for new energy-saving, high-efficiency, stable and easy-to-maintain squeeze dewatering equipment.
To thoroughly address the shortcomings of conventional industry equipment and meet the actual production demands of end customers, this newly upgraded model has been developed by the professional R&D team of Zongheng Machinery through eight months of dedicated technical research, structural optimization and repeated on-site operational tests.
The core extrusion component adopts an integrally formed 304 stainless steel screw. Compared with ordinary welded screws, it delivers superior overall structural strength, wear resistance and corrosion resistance, effectively preventing deformation and abrasion during long-term high-pressure extrusion and greatly extending the service life of the machine.
Drawing on years of experience in solid waste dewatering treatment, the R&D team precisely reoptimized the screw pitch compression ratio and wedge screen structure to build a gradient pressurized dewatering system, enabling more sufficient and even extrusion and dewatering of materials. Meanwhile, the machine is equipped with an all-new intelligent variable-frequency pressure control system, which automatically adjusts extrusion rotation speed and pressure according to material moisture, feeding volume and material type to realize intelligent and precise dewatering. Multiple key performances have achieved breakthrough improvements, making the machine perfectly suitable for dewatering and processing all types of soft waste materials.
After multiple on-site batch working condition tests, the new-generation screw squeezer delivers excellent dewatering performance for commonly recycled materials such as PE agricultural films, PP woven bags and waste chemical fiber fabrics. The final material moisture content can be stably maintained within a high-quality range of 12%–18%, fully meeting the high-standard production requirements for plastic granulation and recycling processing.
Compared with traditional models, the equipment improves overall dewatering efficiency by 25% and reduces power consumption per unit material by 16%, achieving remarkable energy-saving and cost-reducing effects in large-scale production. The newly optimized anti-blocking feeding structure effectively solves the winding and blocking problems of thin and light materials, supporting 24-hour uninterrupted stable operation without jamming, blocking or material residue.
Adopting a scientific modular structure, the machine is convenient to disassemble, clean, inspect and maintain, greatly shortening downtime and improving overall production efficiency. It is perfectly adaptable to conventional production of small and medium-sized recycling plants as well as fully automated large-scale washing lines, covering all-scale renewable resource production scenarios.
According to the production director, all newly mass-produced screw squeezers are manufactured on the company’s upgraded modern production lines featuring intelligent sheet metal processing and precision machining.
Key shafts, pressure-bearing parts and core extrusion components are all processed by CNC precision machining, delivering higher dimensional accuracy, better fitting tolerance and superior operational stability.
Every unit undergoes rigorous high-standard quality inspection, including a 72-hour full-load continuous running test. Inspectors comprehensively check welding quality, sealing performance, transmission systems, electric control systems and other critical components. Strict control is implemented across all manufacturing procedures to prevent defective products from delivery, ensuring stable long-term continuous heavy-duty operation.
At present, this product line covers complete specifications including Model 200, Model 320 and Model 450. Customized integrated solutions of single machine or double linked squeezing units are available based on customers’ actual throughput, plant space and production line configuration, featuring outstanding adaptability for diverse production demands.
