Sandvik Rock Processing has launched its latest generation CH442 and CH662 cone crushers, delivering significant advances in reliability, uptime, automation and maintenance efficiency for mining and quarrying operations worldwide – including across Africa’s demanding crushing environments.
The new models represent the next evolution of Sandvik’s well-established CH400 and CH600 series cone crushers, building on decades of engineering experience to deliver stronger mechanical design, simplified serviceability and enhanced digital connectivity.
“For more than a century, Sandvik has focused on engineering equipment that delivers reliability, safety and long-term performance,” Tarynn Yatras, Vice President – Sales Area Africa at Sandvik Rock Processing Solutions, says. “The new CH442 and CH662 build on that legacy by introducing stronger key components, faster and easier maintenance and intelligent automation that give operators clearer insight and better control of their production.”
The Sandvik CH662 was showcased at CONEXPO 2026, where visitors had the opportunity to see the strengthened design, upgraded automation capabilities and productivity-focused improvements first-hand.
Engineered for uptime and performance
Both crushers have been designed to deliver improved operational stability, higher availability and more efficient maintenance processes. A key innovation is the backing compound-free design, which eliminates the curing time typically required during liner changes – removing up to 24 hours of downtime and allowing maintenance to be completed more quickly.
According to PC Kruger, Business Line Manager – Crushing Solutions at Sandvik Rock Processing, the removal of backing compounds also improves safety and simplifies service procedures.
“By eliminating the need for backing compounds, liner changes become faster and safer while reducing operator exposure to bonding agents,” he explains. “This approach improves crusher availability while also making routine maintenance easier for site teams.”
The crushers are suited to high-capacity secondary crushing, high-reduction tertiary crushing and pebble crushing applications, allowing operators to adapt the machines to a wide range of mining and aggregate processing environments.
Strengthened mechanical design
A major focus of the redesign has been strengthening key components that directly influence uptime and operational reliability.
The top shell has been reinforced with approximately 10% additional weight and improved material distribution, increasing durability under demanding crushing conditions. This is complemented by a newly engineered main shaft designed to further enhance mechanical stability and long-term performance.
Kruger explains that these improvements are aimed at ensuring the crushers deliver predictable performance in high-duty applications.
“The strengthened top shell and upgraded main shaft improve the overall mechanical robustness of the crusher,” he says. “Together with the redesigned spider bushing, these upgrades help maintain consistent crushing performance while supporting longer service intervals.”
The new spider bushing also incorporates an integrated temperature sensor connected to the crusher’s automation system, enabling operators to monitor operating conditions and detect potential issues earlier.
Digital monitoring and smarter control
Both the CH442 and CH662 are equipped with Sandvik’s ACS-c 5 ASRi automation system which enables automated crusher setting regulation and provides role-based access for system monitoring, troubleshooting and performance optimisation.
The machines can also be connected to SAM digital services, Sandvik’s cloud-based platform that provides real-time and aggregated data on crusher performance, wear patterns, alarms and fleet status.
“This level of digital connectivity allows customers to gain deeper insight into crusher performance,” Kruger says. “Operators can monitor equipment condition more effectively, plan maintenance proactively and optimise the crushing process based on real operating data.”
Supporting customers across Africa
For African mining and aggregate producers, equipment reliability and lifecycle support remain critical factors in maintaining consistent production.
Yatras says Sandvik’s regional presence ensures customers receive the technical support and aftermarket services needed to maximise crusher performance over the long term.
“Across Africa, customers are looking for solutions that combine mechanical strength with digital intelligence and reliable aftermarket support,” she says. “Through Sandvik’s regional service footprint and technical expertise, we are well positioned to support customers in getting the best possible performance from these new crushers throughout their lifecycle.”
By combining strengthened mechanical design, simplified maintenance and advanced automation capabilities, the CH442 and CH662 demonstrate Sandvik’s ongoing commitment to delivering safer, smarter and more productive crushing solutions for the global mining and aggregates industries.
Reborn offering
Yatras explains that Sandvik’s Reborn solution allows customers to upgrade an existing Sandvik CH440 or CH660 crusher to the performance level of the new CH442 or CH662 models, while reusing the installed auxiliaries and existing infrastructure. This approach is designed to save time, reduce capital expenditure and extend asset life, while still delivering the key benefits of the next-generation crushers.
“Through the Reborn solution, an existing Sandvik cone crusher can effectively be transformed into a next-generation CH442 or CH662, providing higher uptime, safer maintenance and smarter operation with a lower capital investment,” Yatras concludes.
