SOYU Machinery is an industrial shredding and recycling equipment manufacturer based in Changshu, Jiangsu Province, China. The company designs and manufactures industrial shredders, crushers and recycling systems for a range of waste processing applications.
SOYU's product range includes single shaft shredders, twin shaft shredders, four shaft shredders and application-specific recycling equipment. Machine configurations can be selected according to the material to be processed, required capacity and downstream recycling requirements.
For project enquiries, buyers can provide material photos, sample dimensions, estimated daily throughput and target output size to help SOYU assess a suitable equipment configuration.
Certification requirements depend on the product, its configuration and the intended market. ISO 9001 relates to a quality management system, while CE documentation concerns applicable European product conformity requirements.
Buyers should confirm which certificates and conformity documents apply to the specific machine or recycling line they intend to purchase. The relevant documentation can be reviewed before ordering to help determine whether the equipment meets the project's requirements.
For available company credentials, patents and product conformity documents, visit the SOYU Certificate page.
Component brands and specifications may vary according to the machine model, configuration and project requirements. SOYU equipment configurations may include industrial control components, electrical components, bearings and drive systems selected for the intended operating conditions.
When comparing equipment, buyers should review the motor and gearbox specifications, control system, cutter materials, bearing arrangement and availability of replacement parts. These details help determine whether a machine is appropriate for the intended material and operating schedule.
For a project-specific quotation, request the component list and technical configuration for the proposed machine.
The most suitable shredder depends on the material properties, required output size, processing capacity and downstream process. The three designs have different operating characteristics.
Single shaft shredder: Commonly used for size reduction of plastics, wood waste and other suitable materials where a screen can help control output size. A hydraulic ram may be used to feed material toward the rotor, depending on the design.
Twin shaft shredder: Commonly used for primary size reduction of bulky materials such as metal drums, tires, large containers and selected mixed waste. Two counter-rotating shafts shear and tear the material; output characteristics depend on the cutter design and machine configuration.
Four shaft shredder: Uses four cutting shafts and, in screen-equipped designs, a sizing screen to help control the discharged material size. It can be considered for selected industrial waste streams requiring controlled size reduction.
These are general selection guidelines rather than fixed rules. Material testing and a review of the required output can help determine the appropriate machine.

Industrial shredders may encounter unexpected resistance when processing mixed or bulky materials. Excessive load can place stress on the drive system, gearbox, shafts and cutting components.
Depending on the machine design, overload protection may monitor operating conditions and initiate actions such as stopping or reversing the rotor to reduce the load. The specific protection method and response depend on the installed control and drive system.
Overload protection can help reduce the risk of damage, but it cannot prevent every failure. Correct machine selection, appropriate feeding practices, routine inspection and maintenance remain important for reliable operation.
When evaluating a machine, ask the supplier which overload protection functions are included in the proposed configuration.
A non-ferrous metal recycling line may combine shredding, screening, magnetic separation and non-ferrous metal separation. The equipment arrangement depends on the incoming scrap, the target material fractions and the required recovery quality.
A typical process may reduce the size of scrap material, remove ferrous metals with magnetic separation and use an eddy current separator to recover suitable non-ferrous metal pieces. Additional sorting equipment may be required when the feed contains mixed materials or when tighter separation specifications are needed.
The final material quality and recovery rate depend on feed composition, particle size, contamination, equipment configuration and operating conditions. A process assessment and representative material test can help establish realistic performance expectations.

Wind turbine blades commonly contain fiber-reinforced composite materials, including fiberglass-reinforced plastic (FRP or GFRP). These materials can be challenging to process because of their size, strength and abrasive characteristics.
A suitable recycling system may use staged size reduction and application-specific cutting components to reduce blade sections for downstream handling or recycling. The required process depends on blade dimensions, composite structure, target particle size and the intended end use of the recovered material.
Whether pre-cutting or other preparation is necessary must be assessed for the specific blade and equipment configuration. The proposed system should also account for dust collection, safe handling and the requirements of the downstream recycling process.

Used automotive oil filters may contain residual oil, steel housings, filter media and other components. A recycling line is designed around the filter types, residual oil conditions and the required separation results.
A typical process may involve size reduction to open the filter housing, followed by pressing or another suitable oil-removal stage. Subsequent separation equipment can help recover ferrous metal and separate other fractions where the system is designed to do so.
Actual oil recovery and material purity depend on the incoming filters, process design, operating parameters and maintenance. Any stated recovery percentage should be supported by test data under clearly defined conditions.
Because used oil filters may contain regulated residual oil and contaminants, the project should also include appropriate collection, handling, storage and waste management procedures.

To help evaluate a project, provide as much of the following information as possible:
Material type and representative photos or samples
Maximum material dimensions and composition
Required throughput, such as kilograms or tonnes per hour
Target output size and any separation requirements
Expected operating hours and feeding method
Destination of the processed material and downstream equipment
With these details, SOYU can review the application and recommend a machine configuration for further technical discussion.
