Mobile equipment expands business

A small quarry at Mount Winton, 22km from Tamworth in northern NSW, is poised to substantially boost its markets after an investment in new mobile equipment.

BMR Quarries? Brian Crowe said the equipment has enabled the business to move from its static plant operation to tender for work in other parts of the region.

 ?We can go out and crush now for other people,? Brian said. ?There?s 150 different council and shire pits in our region and we are tendering for a number of different jobs.?

In August last year, Brian Crowe approached Finlay Screening and Crushing, based on the northern outskirts of Brisbane, for solutions on how to upgrade his quarry production and make different products needed to meet tight specifications.
?Brian sent me tests from his quarry rock and I advised him he would need five additional machines to supplement his vertical shaft impactor,? Finlay?s Ronnie Bustard said.

?The machines we supplied to BMR were a primary jaw crusher (Terex Finlay J-1175), a secondary cone crusher with on board screen (Terex Finlay C-1540RS), a triple-deck screening plant (Terex Finlay 694), a two-deck screening plant (Terex Finlay 683) and a stacker (Terex Finlay 532),? Ronnie added.

?We also supplied an agg flow, showing how the machines should be set up and tonnage rates for each of them.

?Brian gave the green light for the project in late December and the machines were up and running for the new year. I believe they are producing more than expected quantities of in-spec material.?

As per Finlay?s recommendations, the Mount Winton quarry now features a mobile fleet lead by a J-1175 jaw crusher, fitted with a Jaques 42 x 30 jaw crushing chamber and heavy duty undercarriage. It has an output of 500 tph, a maximum feed size of 700mm, a hopper size of 9m3 and is powered by a 261kW Caterpillar C9 engine. The J-1175 is complemented by the C-1540RS Automax 1000 cone crusher, with an output of 300 tph, a maximum feed size of 195mm and a hopper size of 5m3. It comprises a 6ft x 4ft pre-screen and a 12ft x 5ft recirculating screen. The remainder of the mobile plant comprises the 532 stacker and the 683 and 694 Supertraks, with outputs of between 400 to 600 tph. The 683 Supertrak features a 12ft x 5ft twin-deck screen, a high capacity 7m3 belt feed hopper with a 1050mm 3-ply conveyor belt, while the 694 features a 20ft x 5ft triple-deck screen with an innovative four-way split. The oversize plus product can be fed into a secondary crusher before re-screening or a fourth product can be stockpiled, which eliminates the need for an additional screen. Brian Crowe said the machines were all ?good gear?.

?We?ve had no problems with them. And dealing with the Finlay guys has been bloody fantastic!? he said.
