Innovative Installation of Fixed Tooth Plate Enhances Performance of CH420 Cone Crusher at Shanghai Zhuyan Facility
Shanghai, China
March 27,2025
In a significant advancement aimed at optimizing operational efficiency, Shanghai Zhuyan has successfully completed the installation of a new fixed tooth plate on its CH420 Bottom Single Cylinder Cone Crusher. The upgrade, carried out by a team of seasoned engineers, marks a critical step in ensuring prolonged equipment durability and enhanced crushing performance for the facility’s aggregate production line.
Installation of the Tooth Plate Process and Technical Precision
The CH420 Bottom Single Cylinder Cone Crusher, renowned for its robust design in secondary and tertiary crushing stages, underwent a meticulous installation process to replace its worn fixed tooth plate—a component vital for material fragmentation. Prior to the installation, the CH420 Bottom Single Cylinder Cone Crusher was safely decommissioned, followed by a thorough inspection of the crushing chamber to assess wear patterns and structural integrity.
Engineers utilized specialized lifting equipment to remove the outdated fixed tooth plate, taking care to preserve the CH420 Bottom Single Cylinder Cone Crusher’s alignment. The new high-manganese steel fixed tooth plate, engineered for exceptional abrasion resistance, was then precision-fitted to ensure seamless integration with the CH420 Bottom Single Cylinder Cone Crusher’s mantle and concave surfaces. Torque specifications were strictly adhered to during bolting, guaranteeing optimal tension and minimizing vibration risks. Post-installation, the team conducted rigorous testing, including a trial run with minimal load to verify alignment and operational smoothness.
Expert Insights and Operational Benefits
A Senior Maintenance Engineer at Shanghai Zhuyan, emphasized the importance of the upgrade:
“The fixed tooth plate is a linchpin in maintaining crushing efficiency. Proper installation reduces downtime and extends the CH420 Bottom Single Cylinder Cone Crusher’s service life, directly impacting productivity.”
The new fixed tooth plate is expected to improve material flow, reduce energy consumption, and deliver a more consistent output size—critical for meeting high-quality aggregate standards.
The project also underscored Shanghai Zhuyan’s commitment to proactive maintenance.
“Regular component upgrades are integral to our operational philosophy. This installation of fixed tooth plate not only addresses wear but also aligns with our safety protocols, reducing the risk of unplanned breakdowns.”
Future-Focused Maintenance Strategy
The successful installation reflects Shanghai Zhuyan’s investment in cutting-edge crushing technology and precision-driven maintenance practices. With the CH420 Bottom Single Cylinder Cone Crusher now operating at peak capacity, the facility anticipates a 15-20% boost in crushing efficiency, alongside reduced maintenance costs over the next fiscal year.
Looking ahead, the company plans to integrate IoT-enabled monitoring systems to track wear in real-time, further revolutionizing its approach to equipment management.
