Aggregate contractor chooses jaw for demanding applications

Quarry Solutions also has a significant mobile crushing and screening capability, with a large fleet of tracked equipment.

The company owns and operates its own equipment at these quarry sites. It has the capability and experience to produce a full range of high quality quarry products to its clients’ specifications, at high daily production rates. Quarry Solutions’ clients include Transport and Main Roads Queensland, NSW Roads and Maritime Services, local councils and the general public.

It also has the capability to undertake dredging works and hydro-transportation to provide the total “quarry solution”.

The company recently supplied large volumes of high quality quarry materials to Pacific Complete for the Woolgoolga to Ballina section of the Pacific Highway Upgrade.

{{quote-A:R-W:300-Q:"The machine is robust and very well engineered, as people come to expect from Metso,"}}To cater for this major infrastructure project and the underlying demand for construction materials in the Northern Rivers region, Quarry Solutions established that its business could benefit from a large, reliable mobile jaw crusher to transport between its quarries and mobile project sites.

Quarry Solutions’ plant and asset manager Alan Lippiatt made approaches to the few mobile crusher suppliers he knew could meet his quality and processing specifications. He required a large, very reliable jaw crusher with efficient pre-scalping at the feeder.

Lippiatt has been involved in the crushing industry for more than 15 years in various roles, so he had a very clear idea what was required.

Tutt Bryant Equipment (TBE), the Metso Lokotrack distributor for Australia, was fortunate enough to have an LT120 jaw crusher on a ship about to sail past Brisbane for its intended port of Perth.

The guys at TBE decided to take a punt and offload the unit so the Quarry Solutions team could inspect it within their time frame.

During the decision-making process, Lippiatt contacted other LT120 owners for their opinions on the machine’s performance. Shortly after an inspection, Quarry Solutions purchased the LT120 jaw crusher and put it straight into operation at its Petersen’s Quarry at Coraki.

The LT120 was put to work in the first week of August and is exceeding expectations.

{{image2-a:r-w:200}}“The machine is robust and very well engineered, as people come to expect from Metso,” Lippiatt said. “Our operational guys are trying to put it through its paces, but probably need a bigger excavator to do that!”

Quarry Solutions’ LT120 is fitted with Metso’s ICr (wireless information and control) system, to allow the excavator operator to change parameters on the machine without leaving the confines of his cab.

It is also connected with Metso’s Metrics Services system, which allows the owners to monitor the machine’s performance remotely and assist the operational staff with any issues. The TBE service team also has access to this data, so they can work with the operators to clarify any process changes they need to make.

Metso has engineered an aggressive throw in the scalper and matched it with a large side conveyor that can be fixed to either side of the machine. This ensures that the fines selected for scalping can be removed quickly. The C120 jaw has an excellent nip angle, variable stroke and superior crusher kinematics to provide high crushing power throughout the entire cavity.

With a jaw 400mm deeper than its LT3054 predecessor, the enhanced kinematics and high flywheel inertia allow the LT120 jaw crusher to have fewer power peaks, reducing engine load, which can provide less than 30 litres per hour (<30lt/hr) fuel usage.

Tutt Bryant Equipment continues to support Quarry Solutions with parts and service support as required.
