Metso's Three New Primary Crushers – How OCP Mechanical Provides Reliable Alternatives

Why Metso’s three new primary crushers represent a significant step forward in primary crushing technology – and how OCP Mechanical offers reliable alternatives for operators seeking proven performance and factory-direct value

On June 3, 2026, Metso announced the launch of three new primary crushers – Metso Primarok, Metso Optirok, and Metso Durarok – engineered to address the diverse needs of modern mining operations. According to Metso, 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. Primarok is built on more than a century of experience in gyratory crushing and offers the highest capacity of any gyratory on the market. Optirok is an evolution of the primary jaw crusher, designed for high-capacity crushing in compact footprints with limited space and height. Durarok is a robust primary sizer engineered for maximum endurance, well suited for handling sticky materials, soft to medium hard ores, and demanding mining applications. For quarry operators, mining companies, and aggregate producers, this launch signals a clear industry direction: primary crushing equipment is moving toward greater safety, higher availability, and optimized performance for specific applications. At OCP Mechanical Company, with over 40 years of manufacturing experience, we supply a comprehensive range of crushing and screening equipment – including PE Series jaw crushers, HST Series cone crushers, and VSI 6X sand making machines – designed to deliver reliable performance across primary, secondary, and tertiary applications, all at factory-direct prices.

Primarok – the gyratory solution for high-capacity, high-availability primary crushing

Metso Primarok is engineered for unmatched performance and the highest availability in its class. Built on more than a century of experience in gyratory crushing, the 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. Every maintenance task has been streamlined to maximize efficiency and safety, allowing for quick and secure shutdowns. For large-scale mining operations processing high volumes of hard rock, the Primarok represents a significant advancement in primary gyratory crushing technology. While gyratory crushers of this scale are typically used in the largest mining operations, OCP Mechanical offers a complete range of primary crushing solutions – including PE Series and PEW Series jaw crushers – engineered for reliable performance in quarry and aggregate applications. Our jaw crushers are designed with heavy-duty construction, hydraulic adjustment systems, and easy maintenance access, delivering consistent performance across a wide range of feed materials and operating conditions.

Optirok – high-capacity jaw crushing in a compact footprint

Metso Optirok is an evolution of the primary jaw crusher, designed for 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. For operators with space constraints or those looking to upgrade from older jaw crusher designs, the Optirok represents a significant step forward in jaw crusher technology. At OCP Mechanical, our PEW Series jaw crushers are engineered with many of the same performance-focused features now being highlighted as industry benchmarks – hydraulic wedge adjustment systems, synchronized retraction arrangements, and robust mechanical designs. These features enable faster setting changes, reduced downtime, and improved product quality, all at factory-direct prices.

Durarok – a robust sizer for demanding and variable materials

Metso Durarok is a robust, simplified sizer designed for maximum endurance. 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. For operations processing variable feed materials with moisture constraints, the Durarok offers a robust solution. While sizers are typically used in specific applications, OCP Mechanical offers a comprehensive range of primary, secondary, and tertiary crushing equipment designed to handle a wide variety of materials – from hard granite and basalt to softer limestone and recycled materials. Our equipment is engineered for versatility, enabling operators to process different feed materials without compromising performance or product quality.

What these launches mean for crushing equipment buyers – and how OCP Mechanical delivers value

Metso's launch of three new primary crushers reflects a broader industry trend: equipment manufacturers are moving toward more application-specific solutions that offer higher safety, greater availability, and lower total cost of ownership. For quarry operators and mining companies, this means that modern crushing equipment is designed to be more predictable, safer to maintain, and optimized for specific applications. The emphasis on safety, ease of maintenance, and uptime is a clear response to operator demands for equipment that reduces downtime and improves productivity. While these innovations from major manufacturers continue to raise the bar for the industry, OCP Mechanical Company, with over 40 years of manufacturing experience, supplies PE Series and PEW Series jaw crushers, HST Series cone crushers, and VSI 6X sand making machines that incorporate many of the same performance-focused features now being highlighted as industry benchmarks – robust mechanical designs, hydraulic adjustment systems, and automation-ready platforms – all at factory-direct prices. Our equipment is designed to deliver reliable performance, consistent product quality, and low operating costs, enabling operators to achieve their production targets efficiently. With a proven track record of serving customers across more than 180 countries and regions, OCP Mechanical offers a trusted alternative for operators who value both quality and value.
