(PRESS RELEASE) ESPOO, 20-Nov-2025 — /EuropaWire/ — Metso has introduced the SCDH4500, the company’s largest split geared ring model to date, marking a significant advancement in the modernization of thickener maintenance for the mining industry. The new solution reinforces Metso’s commitment to enhancing equipment reliability, improving operational safety, and supporting more sustainable mining practices. With this latest development, customers can expect shorter maintenance shutdowns, safer working conditions, and reduced overall service costs.

The SCDH4500 was engineered to overcome the well-known challenges associated with replacing traditional full slew bearings. Its innovative two-piece split configuration allows installation times to be reduced by as much as 50%, and importantly, eliminates the need for large-scale system disassembly. By removing the requirement for major crane lifts and suspended loads, the design significantly enhances safety while delivering cost savings across labour, equipment rental, and lost production.

This launch also aligns with Metso’s broader strategy to strengthen its thickener technology portfolio and expand its aftermarket solutions. With a design that integrates seamlessly with existing SCD drive geometries, the SCDH4500 provides a scalable solution that delivers consistent, reliable performance in high-torque, heavy-duty environments. It supports customers seeking efficiency improvements across the entire lifecycle of their thickening equipment.

Andrew McIntosh, Product Director for Thickening Services at Metso, emphasized the practical benefits of the new model. He noted that the two-piece split design not only accelerates installation and reduces disruption but also significantly improves safety outcomes by avoiding the risks associated with large cranes and suspended components. He added that compatibility with current SCD drive geometries ensures robust performance in demanding applications.
