Metso Launches New Primary Crushers

Metso has launched 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, according to Metso.

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

"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," added Oksanen. "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."

Primary Crushing Solutions for Every Application

The Primarok is built on more than a century of experience in gyratory crushing and can handle the most demanding primary crushing applications with ease, according to Metso. Its optimized kinematics, refined chamber design and ability to accept large feed sizes drive high efficiency and stable performance. The Primarok also allows for quick and secure shutdowns, as every maintenance task has been streamlined to maximize efficiency and safety, added Metso.

The Metso Optirok "takes crushing to a completely new level in applications with limited space and height," said Metso. "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."

The Metso Durarok primary sizer combines a simplified, heavy-duty design with high performance and durability, according to Metso.

"Its crushing rolls are engineered to withstand the heaviest loads and generate high crushing forces while maintaining low wear rates," the company added. "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."
