Double Shaft-Based Solar Cell Crushing Unit
As photovoltaic modules enter a concentrated phase of end-of-life disposal, efficient and safe pre-processing of solar panels has become a critical step in recycling production lines. Due to the complex structure of solar panels—which incorporate multiple materials including glass, aluminum frames, plastic backsheets, and silicon wafers—direct crushing is not only inefficient but also prone to causing equipment damage. Addressing this practical need, SUNY GROUP's dual-shaft shredder is widely deployed in the front-end crushing stage of solar panel recycling, fulfilling the core functions of “reducing size and ensuring stable feeding.”
I. Operational Logic
The dual-shaft shredder primarily handles pre-crushing of solar panels. Entire panels or frames removed from photovoltaic modules can be fed directly into the shredding chamber. Two low-speed, high-torque cutting shafts rotate in opposite directions, actively gripping materials. Through a combined action of shearing, tearing, and squeezing, large solar panels are shredded into uniform chunks.
This process prioritizes addressing the challenges of “large volume, high strength, and rigid structure” over achieving fine fragmentation in a single pass. It ensures the material size is better suited for subsequent crushing, sorting, or pulverizing stages. Post-pre-shredding, not only does the processing capacity of downstream equipment significantly increase, but blade wear is also substantially reduced, leading to more stable overall line operation.
II. Core Structure
This dual-shaft shredder features heavy-duty industrial construction. Its frame is welded from thick steel plates and profiles, delivering exceptional rigidity to withstand prolonged high-load operation. Cutting blades are crafted from premium alloy steel through specialized heat treatment, offering outstanding wear resistance and impact toughness—ideal for shredding solar panels containing glass and composite materials.
The equipment is equipped with a Siemens PLC intelligent control system for real-time monitoring of operational status. Upon encountering metallic foreign objects, material jams, or transient overloads, the system automatically shuts down and reverses the cutter shafts. Normal operation resumes after obstacle clearance, effectively preventing equipment damage. The transmission system utilizes planetary gear reducers, offering advantages over traditional gearboxes, including high efficiency, compact size, high torque density, and stable operation—making it highly suitable for low-speed, high-torque applications.
III. Application Advantages
Within photovoltaic recycling lines, the dual-shaft solar panel shredder serves either as primary crushing equipment or as a secondary pre-treatment unit. Its large feed chamber accommodates direct forklift loading, demonstrating strong adaptability to varying panel sizes and configurations while reducing reliance on manual disassembly. The modular blade design ensures safer, more convenient maintenance and replacement, minimizing downtime.
From an overall operational perspective, the integration of dual-shaft shredders clarifies and enhances control over the solar panel recycling process. This creates stable conditions for subsequent crushing, sorting, and material recovery, making it an indispensable key component in building efficient, sustainable photovoltaic recycling systems.
