en.Wedoany.com Reported - Recently, Metso Corporation of Finland officially launched three new primary crushers for the global mining industry—Primarok™, Optirok™, and Durarok™. These three crushers utilize gyratory, jaw, and tooth-roll crushing technologies respectively, aiming to enhance the processing capacity, safety, and equipment availability of primary crushing operations while reducing total cost of ownership.
Metso is a global mineral processing and metal smelting technology company headquartered in Espoo, Finland, serving industries including mining, aggregates, energy, and metal recycling. As of the end of 2025, the company had nearly 18,000 employees in approximately 50 countries, with sales of about €5.3 billion in 2025, and is listed on Nasdaq Helsinki. Olli-Pekka Oksanen, Senior Vice President of Metso's Crushing business, stated that the primary crushing process, as the starting point of the beneficiation flow, lays a crucial foundation for the overall recovery efficiency of the mine. The new crushers are based on proven technologies and integrate data-driven services and performance optimization solutions, elevating performance, availability, and maintainability to new levels.
The three crushers each feature distinct technical characteristics. Primarok leverages Metso's century-long experience in gyratory crusher development, employing optimized kinematic design and an improved crushing chamber to handle large feed sizes, achieving high efficiency and stable performance. All maintenance procedures for this model have been streamlined, allowing for quick and safe shutdowns. Metso claims its capacity exceeds that of any other gyratory crusher on the market. Optirok is an evolution of the jaw crusher, specifically designed for space- and height-constrained applications, offering high capacity, integrated pre-screening, and a high reduction ratio, capable of handling large volumes of run-of-mine material and withstanding hard rock and highly abrasive materials. Its innovative design simplifies maintenance. Durarok is a robust tooth-roll crusher featuring a heavy-duty structural design with reinforced crushing rolls that can withstand extreme loads while maintaining low wear rates. This model is suitable for sticky materials and soft to medium-hard ores, achieving higher utilization and uptime compared to traditional solutions.
The global mining industry is facing pressures from declining ore grades and rising operational costs. Metso's new crushers are expected to help mining companies optimize the economics of the primary crushing stage by improving equipment utilization and reducing maintenance costs. The company will host a webinar on June 17 to further detail the product features.
