Sandvik cone crushers go circular with recycled wear parts

Sandvik Group is encouraging circularity in the mining industry through the recycling of steel from used cone crusher parts to make new crushing equipment.

While extractive industries such as mining are responsible for 50% of global carbon dioxide (CO2) emissions, recycling steel from mining equipment could make all the difference, according to Anders Åkesson, QM EHS Manager, Crushing & Screening at Sandvik Mining & Rock Technology (SMRT).

Circularity is becoming vital in the reduction of CO2 emissions, and can help improve the environmental position of many industries. With the mining industry contributing a large percentage of global CO2 emissions, implementing circularity could help it make vital reductions, Åkesson says.

To produce equipment, the mining industry predominantly uses manganese steel, which is renowned for its work-hardening properties and resistance to abrasion. This means the material becomes harder with the more impact it receives, creating a low friction surface suited to crushing. For this reason, manganese steel has been used in high impact applications for over 100 years, making it an ideal material for cone crushers.

Cone crushers are used to grind down rocks, which are fed into the top of the crusher and pressed between the mantle and the cone. This breaks the rock down into smaller fragments, which are then passed through lower levels of the crusher where they are broken down further.

“It’s vital that cone crushers are made from a material that provides the necessary force to grind the rocks, while withstanding the abrasive nature of the process,” Åkesson said.

Using recycled steel from used cone crusher parts to make new cone crushers, Sandvik SMRT has demonstrated and improved circularity of steel production for mining equipment, he explained. The division was nominated for Sandvik’s first sustainability award in April 2020, which recognises sustainable innovations from its employees.

Sourcing manganese steel from one of the world’s most sustainable manganese foundries, based in Sweden, was the first step SMRT took towards its sustainable innovation. A total of 91% circular steel was used to manufacture wear parts, such as the cone and mantle of a cone crusher. These wear parts are reused to produce new wear parts for the cone crushers – creating a continuous cycle, Åkesson said.

Moving away from a linear model, Sandvik increased the circularity and sustainability of its products and eliminated 79% of production emissions, according to Åkesson. “In addition, Sandvik cone crushers help SMRT’s customers to lower their environmental impact as they are buying from the circular economy – contributing to their own sustainability goals,” he said.

Åkesson concluded: “With mining contributing towards CO2 emissions in more ways than one, it’s essential that the industry uses methods that reduce emissions. Reusing and recycling steel to manufacture mining equipment has demonstrated an opportunity that helps meet the sustainability goals of both equipment suppliers and their customers. If the industry wants to become circular, taking a look at equipment a good place to start.”

Sandvik bolts on three more “connected crushers” to 800i series

Sandvik says it is expanding its 800i series of cone crushers to include three new models that come equipped, as standard, with an Automation and Connectivity System (ACS).

The new Sandvik 800i series of cone crushers feature mechanical upgrades, connectivity, advanced automation and rebuild possibilities to predict performance, maximise uptime and offer the best in sustainability at the lowest possible cost, Sandvik says.

Sandvik launched the series of “connected crushers” in July 2018.

The three new models – CH830i, CH840i and CS840i – means the 800i crusher series has been improved and extended to offer reliable, intelligent crushing to any mining or aggregate application, according to the company. Connected to My Sandvik, the crushers enable managers and operators to “make decisions based on facts, and see areas for improvement directly, increasing uptime and availability”, Sandvik said.

The ACS continuously monitors and optimises crusher performance and controls the complete lubrication system, increasing uptime and reliability, according to the mining OEM. It replaces the ASRi™ system that was previously in use for the 800i series of cone crushers.

The 800i series has been “toughened and improved to offer greater reliability, higher availability and a low risk of critical failure”, Sandvik says. This sees the crushers have bolted rather than welded top and bottom shell liners making a changeout 90% faster, according to the company.

The over-pressure system keeps dust out, and the standard offline filter keeps oil cleaner, extending oil life by, the company says, up to five times.

“More power output from less energy and more uptime through intelligent crushing make the 800i series a safer, more sustainable choice,” Sandvik said.

The 800i crusher series can be purchased as a completely new crusher, or as a Sandvik REBORN solution, replacing an existing crusher and reusing existing auxiliaries and infrastructure, according to the company. “This plug and play installation minimises disruption and maximises productivity, while offering up to 40% cost savings compared to a complete crusher system,” Sandvik said.

Such a solution was recently installed at the Mantos Blancos copper mine in Chile.

These new crushers also come with Sandvik’s service agreement, which, it says, provides customers with safer operations, low operating costs and long service life. This can increase productivity by up to 10%, according to the company.

Mats Dahlberg, Vice President Lifecycle Service, Stationary Crushing and Screening, said new, digital technologies will transform the way mines and quarries work.

“My Sandvik is the first major step in gaining insights into productivity and predictive maintenance that will drive our industry forward,” he said. “It’s great to offer our customers a service that will truly make a difference to their profitability.”

Metso to keep its crushers working for longer with O-Series liners

Metso says it is expanding its crusher wear part offering by launching a new range of OEM crusher liners.

Available for selected markets from September, the new Metso O-Series offers the right balance between performance, affordability and reliability, the company said.

Olli Heinonen, Head of O-Series development at Metso, said: “The Metso O-Series offers a value-priced alternative that is ideal when you need to focus on optimising daily operations, while our premium crusher wears range ensures additional durability, performance and maximum return on investment.”

The Metso O-Series range is now available for Metso Nordberg® HP Series™ and GP Series™ cone crushers as well as C Series™ jaw crushers, Metso said. In the first phase, the new range will be sold through Metso sales offices, and the accredited Metso distributors in China, Mexico, Central America, and Asia Pacific.

Heinonen concluded: “The Metso O-Series was created in close cooperation and dialogue with our customers to especially meet the business requirements in rapidly developing markets. We are excited about this new range and the new opportunities to help our customers get better control of their operations without compromising on quality. Going forward, we’re looking into bringing further crusher models to the range as well as introducing it to additional markets.”
