Jaw crusher becomes fifth Powerscreen machine delivered to Gromac

The mobile Powerscreen Premiertrak 600 provides flexibility and mobility to Gromac Quarries.

Lincom Group’s high-performance Powerscreen Premiertrak 600 crusher has attracted five orders in the past 18 months. Australian Mining writes.

Mobile equipment is the best suited to service the market of Gromac Quarries, for example, when North Queensland faced unprecedented flooding in February.

The Queensland Government was redeveloping a rail line between Townsville and Mount Isa, a project that covered more than 200 kilometres (according to Queensland Rail).

The railway project would ensure the state’s key freight routes efficiently connect mining regions to ports, airports and other transport hubs.

“Having a mobile plant gives them the versatility to move their plant to the busy locations in a short space of time, getting into high production and serving demand from customers like Queensland Rail to help deal with situations like the North Queensland flood,” Lincom Group sales manager – North Queensland, North Territory and Papua New Guinea Erwin Koch tells Australian Mining.

The 600-tonne-an-hour jaw crusher was chosen for its capacity for processing ores and minerals, overburden, or aggregates for use in railway ballast. Its portability also ticks off Gromac Quarries’ requirements for versatility.

The Powerscreen Premiertrak 600 has also demonstrated it can increase productivity by up to 30 per cent by removing bridged rock and breaking oversize material in the hopper without the need to stop a plant or reposition the equipment.

It runs on a direct drive Caterpillar C13 engine with 440 horsepower, which Lincom claims is the best transmission power available from an engine, while also being the most fuel efficient.

The Premiertrak 600 promotes aggressive crushing action with low noise emissions and a high swing jaw, which encourages material entry into the crushing chamber alongside a wide bypass chute.

One of Gromac Quarries’ purchasing decisions was driven by a working relationship between the company’s two brothers and Koch, who was personally involved in the commissioning of the machine.

Lincom flew its service technicians from the Brisbane head office for the commissioning and personal training of the equipment for the Gromac Quarries team.

Gromac Quarries has purchased machineries from other suppliers over the life of its business, but found they received the best service from Lincom over the past couple of years, according to Koch.

“We provide all of the training, servicing support and machine spare parts from our head office in Brisbane, so it suits their requirements in North Queensland very well,” he says.

“In the event of any breakdown, they can either get our technical support over the phone or have people come to the site at any given day.”

Lincom Group also boasts a variety of genuine spare parts for its brands, including Powerscreen, as well as a rapid response parts service area to get mining machines up and running with the least downtime.

“We treat every parts order as urgent and understand the potential costs associated with having a machine down,” Lincom Group chief executive Stephen Watterson says.

“Our national parts distribution centre located in Brisbane stocks an extensive range of parts to support the branches in Australia and New Zealand.”

Koch visited one of Gromac Quarries’ sites to discuss its requirements for high output, versatile equipment. He understands the different material processed in the company’s various locations and has tailored the machine’s optional features to Gromac’s specifications.

The remote-control rock hammer option, for example, aids with oversize material entering the chamber – an advanced, high performance 1200 millimetres by 820 millimetres Terex chamber with robust construction for tough applications.

The jaw crusher is driven by the efficient Caterpillar C13 engine.

 

Its users can also equip the crusher with a hydraulic unblock feature to help unclog any unexpected blockages in the crushing chamber.

“This option improves the safety of personnel as you no longer have to physically remove any of the rocks by hand from the machine,” Koch says. “The unblock feature can deal with whatever blockages it encounters.”

Lincom Group has also released a pan feeder and live pre-screen option that removes some of the lesser quality and clay-bound material from the main product to produce either concrete aggregate or high-quality road base.

The compact Premiertrak 600 has an extensive range of options that include remote monitoring telemetry pulse system, electric cabinet positive pressurisation, extended discharge conveyor, to name a few, along with the standard things Lincom fits like conveyor guarding, lanyard safety pull, fire extinguisher and other possible site-specific options.

The success of Gromac Quarries post-North Queensland’s flooding demonstrates Lincom Group’s expertise in the provision of screening and crushing equipment, according to the company.
