Metso is strengthening its prominent position as a crushing solutions supplier with the launch of three new primary crushers — Metso Primarok™, Metso Optirok™, and Metso Durarok™.

Engineered to address the diverse needs of modern mining operations, these high-performance crushers offer superior capacity, safer maintenance, as well as the lowest capital expenditure and total cost of ownership across a wide range of primary crushing applications and ore types.

“Mining operations today require crushing solutions that are not only powerful, but predictable, safe, and optimized for the specific application. At the same time, primary crushing as the first stage in concentrate processing lays the foundation for overall recovery efficiency,” said Olli-Pekka Oksanen, senior vice president, Crushing at Metso.

“Built on proven technologies complemented with major new features, including, for example, data-driven services and performance solutions, the new crushers take performance, availability, and maintainability to a totally new level, resulting in lower total cost of ownership. Primarok offers the highest capacity of any gyratory on the market, while Optirok is designed to address high-capacity primary crushing in compact footprints. Durarok, on the other hand, is a robust solution for materials with variability and moisture constraints and demanding operating conditions,” added Oksanen.

• Metso Primarok™ – engineered for unmatched performance and highest
  availability
Built on more than a century of experience in gyratory crushing, the Metso Primarok can handle the most demanding primary crushing applications with ease. Its optimized kinematics, refined chamber design and ability to accept large feed sizes drive high efficiency and stable performance. On top of this, it allows for quick and secure shutdowns, as every maintenance task has been streamlined to maximize efficiency and safety.

• Metso Optirok™ – high capacity crushing in a compact footprint
As an evolution of the primary jaw crusher, Metso Optirok takes crushing to a completely new level in applications with limited space and height. It delivers unmatched productivity, integrated scalping and a high reduction ratio, efficiently processing large volumes of run of mine material while enduring hard rock and abrasive applications. Its innovative features simplify maintenance, improving safety and reducing downtime.

• Metso Durarok™ – robust, simplified sizer designed for maximum endurance
The Metso Durarok primary sizer combines a simplified, heavy duty design with high performance and durability. Its crushing rolls are engineered to withstand the heaviest loads and generate high crushing forces while maintaining low wear rates. Durarok enables higher utilization and uptime compared to conventional solutions, helping reduce operating costs and increase capacity. It is well suited for handling sticky materials, soft to medium hard ores, and demanding mining applications.

Metso has delivered thousands of crushers to mining and aggregates customers around the world, building a wide installed base across applications and commodities. The new primary crushers further strengthen Metso’s comprehensive crushing portfolio, which also includes well established jaw, cone, impact, and gyratory crushers, which are available as stationary, semi-mobile and mobile solutions. As a leading provider of minerals processing solutions and services, Metso’s offering also covers lifecycle services and upgrades, as well as data-driven services and performance based service models.

Metso is a frontrunner in sustainable technologies, end-to-end solutions and services for the aggregates, minerals processing and metals refining industries globally. They improve its customers’ energy and water efficiency, increase their productivity, and reduce environmental risks with their product and service expertise. Metso is headquartered in Espoo, Finland. At the end of 2025 Metso had close to 18,000 employees in around 50 countries.
