Weir Minerals introduce the Trio TC84XR

Trio TC84XR cone crusher

New and upgraded live-shaft cone crusher design improves safety, functionality, and reliability

WEIR Minerals have upgraded their Trio TC live-shaft cone crusher range with the introduction of the new Trio TC84XR model, which features all the robust design elements that have made live-shaft crushers a fixture of the sand and aggregate industries for generations, whilst also incorporating the latest technology.

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, and 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 with 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 have resisted this trend, believing that because every operation is different, there cannot be a one-size-fits-all approach.

They say there are some applications and situations where pedestal (fixed-shaft) style crushers may be the more appropriate solution, which is why they continue to manufacture the premium Trio TP pedestal style machine, making them the only global equipment manufacturer to offer both TC live-shaft and TP fixed-shaft 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,’ said Mr Utecht.

Trio live-shaft and fixed-shaft cone crushers are made for modern mine and quarry operations with advanced hydraulics, wear-resistant material, and the latest technology.

‘This is really exciting for our customers, as they now have a real choice,’ said Ekkhart Matthies, Weir Minerals’ global application director. ‘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 a straightforward process because it has very similar dimensions and is of comparable weight to its live-shaft predecessors. Moreover, because it produces the same product, downstream changes are not required, which is not the case when replacing a live-shaft style machine with a fixed-shaft style machine. In other words, there is no need to redesign existing circuits.

Moreover, the recent technology upgrades in the Trio TC84XR crusher are said to have improved its safety, functionality, and reliability.

‘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 the 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,’ said Mr Matthies.

Engineered to perform in the most extreme applications, the Trio TC84XR crusher is said to be robust and easy to maintain and operate, and reliably delivers high crushing force and high horsepower.

The ability of the TC84XR crusher to handle variable feed and crush pebbles is also partly a result of its large motor, giving it a higher power capability than comparable cone crushers.

Another feature that allows it to handle variable feed, as well as deal with tramp material safely, is its 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.

In addition, the socket assembly has been redesigned to improve sealing, and the countershaft assembly has been redesigned to remove welding and machining, whilst simultaneously improving venting and the dust seal.

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