Robotic Zinc Cathode Stripping Machine (Dual Station)
The PRS Robotic Zinc Cathode Stripping Machine (Dual Station) is purpose-built by our in-house engineering team to solve long-standing pain points in large-scale zinc hydrometallurgical operations: low stripping throughput, high cathode plate damage rates, and elevated maintenance costs. This fully automated system handles the complete zinc cathode processing workflow — from pre-opening and pure zinc layer removal to plate brushing and final stacking — with minimal manual intervention, ensuring consistent, reliable performance even in continuous 24/7 plant operations.

Core Design & Performance Features
Every feature of the PRS Robotic Zinc Cathode Stripping Machine (Dual Station) is engineered around the real-world needs of zinc electrowinning plants, balancing high throughput with low operational risk and long-term reliability:
- Modular, plant-friendly design: PRS’s modular structural design simplifies on-site installation and routine maintenance access, with an intuitive operator interface that requires minimal training for in-plant staff to operate and troubleshoot.
- Steady high-throughput operation: The dual-station configuration delivers a consistent 700 plates per hour throughput under normal process conditions, outperforming traditional single-station mechanical and manual stripping setups by up to 75%.
- Broad plate compatibility: The system is engineered to work with all standard industry zinc cathode plate specifications, with flexible program adjustments to accommodate minor plate dimension variations without reconfiguration.
- Precise automatic plate tracking & alignment: The robotic system uses real-time plate tracking to ensure micron-level precise motion alignment during every step of the stripping process, eliminating misalignment-related cathode plate damage and reducing scrap rates.
- Integrated automatic defect detection & protection: Built-in defect detection identifies abnormal plates (such as burnt, warped, or uneven plates) in real time, with closed-loop torque control that stops the stripping process immediately to protect both the cathode plate and the equipment from damage.
