Weir Minerals updates Trio live-shaft cone crusher range with TC84XR

Weir Minerals has upgraded its range of Trio® TC live-shaft cone crushers, incorporating the latest technology to ensure it remains integral to flowsheets long into the future, the OEM says.

The Trio® TC84XR features all the robust design elements that have made live-shaft crushers a fixture of the mining and sand and aggregate industries for generations, but updated it with new smarts, according to Weir Minerals.

Mark Utecht, Weir Minerals’ Director of Comminution Engineering, said: “The Trio TC cone crushers’ live-shaft design has been proven to perform in heavy-duty secondary and tertiary crushing applications. We wanted to build on this strong foundation. My team followed a comprehensive design process – we’ve reviewed and tested every inch of this crusher. While the TC84XR may seem familiar on the outside, we’ve upgraded its design and control functionality. The motor is larger and it has a much higher crushing capacity compared to equivalent sized crushers.

“The result: we now have an incredibly robust, powerful and technologically advanced crusher that is easy to operate, has a low wear rate and uses less energy, which ultimately lowers operating costs.”

While many OEMs have made the decision to discontinue their live-shaft cone crushers, Weir Minerals says it has resisted this trend, believing that, because every mining and sand and aggregate operation is different, there can’t be a one-size-fits all approach.

There are some applications and situations where pedestal (fixed-shaft) style crushers may be the more appropriate solution, which is why Weir Minerals continues to manufacture the premium Trio TP pedestal style machine, it said. Weir Minerals claims to be the only global equipment manufacturer offering both the TC live shaft and TP fixed shaft style machines.

“The combination of the Trio TP and TC fixed and live-shaft cone crushers ensures that Weir Minerals continue to offer their customers the right technology, regardless of their site structure, operating conditions or application,” Utecht said.

Trio live- and fixed-shaft cone crushers are made for modern mines and quarries with advanced hydraulics, wear resistant material and the latest technology, according to the company.

Ekkhart Matthies, Weir Minerals’ Global Application Director, said: “This is really exciting for our customers, as they now have a real choice. The combination of our TC and TP series allows us to have an honest conversation with our customers on the options available to them and make a technological recommendation which truly meets their needs.”

Replacing existing live-shaft style machines on site with the Trio TC84XR crusher is now a straightforward process because it has very similar dimensions and is a comparable weight to its live-shaft predecessors, Weir says. And because it produces the same product, downstream changes aren’t required, which isn’t the case when replacing a live-shaft style machine with a fixed-shaft style machine.

“In other words, there is no need to re-design existing circuits,” the company said.

Technology upgrades

The recent technology upgrades in the Trio TC84XR crusher have improved its safety, functionality and reliability, according to the OEM.

Matthies explained: “At Weir Minerals, we understand and appreciate the important role live-shaft cone crushers play in today’s challenging crushing applications. Combining decades of experience and first-hand customer feedback with innovative designs, the highest quality materials and latest in control technology, we believe that our new Trio TC84XR cone crusher is the most reliable and robust live-shaft cone in the market today.”

Engineered to perform in the most extreme applications, the Trio TC84XR crusher is robust and easy to maintain and operate, according to the company. It reliably delivers high crushing force and high horsepower in primary, crushed ore and quarry rock applications.

The ability of the TC84XR crusher to handle variable feed and crush pebbles is also partly a result of its large motor; it’s been designed with higher power capability than comparable cone crushers. Ultimately, this translates to a higher potential crushing force and, therefore, increase in production, Weir said.

Another feature that allows it to handle variable feed, as well as deal with tramp material safely, is the fully-automated tramp-release and setting recovery system. The tramp release hydraulics can also be used to safely clear the crushing chamber should a sudden disruption in plant power cause a shutdown of the cone crusher.

The socket assembly has been redesigned to improve sealing, which has optimised functionality and manufacturability by reducing the machining setups of the socket and seal rings, it said. The Weir comminution team has also redesigned the countershaft assembly to remove welding and machining, while simultaneously improving venting and the dust seal.

The Trio TC84XR crusher, like the range of TP series cone crushers, can be fitted with ESCO® wear parts, designed with superior ESCO alloys, which can be custom designed based on specific requirements.

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.”
