Century crushing technology

increase their flexibility and, more impor- tantly, reduce operating costs.

Trio Top Performance (TP) cone crushers The Trio TP cone crusher has been engi- neered with a unique combination of high crushing force, high throw and high pivot point; these characteristics facili- tate continuous performance and allow the operation to maximise its return on investment. The machine has a steep crushing chamber angle, a large crushing stroke, and operates at optimum speed to deliver a finer product. The high pivot point pro- vides a greater reduction ratio at the top of the head, resulting in greater flexibility in feed size and higher production. The large throw crushing action facilitates maximum throughput and increased interparticle breakage. “The crusher is 10% heavier than com- parable machines, allowing it to accom- modate an increased throw,” Sukdhoe says. The robust three-arm frame design, inside the one-piece cast high strength alloy steel mainframe of the Trio TP cone crusher, provides more discharging space for the crushed material. It also reduces material build up inside the machine. A number of integral self-protecting features provide high levels of mechan- ical reliability in the harshest operating conditions. One such feature is the unique anti-spin device which provides continu- ous proper alignment of bearings inside the crusher. Sukdhoe explains that this device ensures that the machine will instantly crush rock as it is introduced to the crusher. The advanced hydraulic system on the Trio TP cone crushers features pre-charged accumulators and relief valves. This ensures the safety of both operator and equipment. The fully-integrated hydraulic console is equipped with push buttons for moni- toring and controlling the crushing force, bowl thread clamping and crusher Closed Side Setting (CSS) adjustment.

The Trio TP cone crusher is equipped with temperature, flow and pressure sen- sors that are integrated into a cloud-based data management system.“This allows the creation of an individual crusher main- tenance and operating profile, further enhancing performance and reducing operational costs,” Sukdhoe says. Ease of maintenance and servicing has been addressed through the design of the machine. The compact counter- shaft box assembly with pinion gear can be easily removed without disassembly of the crusher. This also provides a more structurally stable machine. The Trio TP range of cone crushers can be installed as a single machine or combined with a full product line of Trio crushers, screens and conveyors to pro- vide total solutions for stationary, porta- ble or modular plants. Trio Vertical Shaft Impact (VSI) crusher Engineered for use in tertiary or quater- nary stage crushing, the Trio VSI crusher is suitable for a wide range of applications including the production of high quality manufactured sand and premium shaped aggregates.
