Crushing & Screening
Omega’s dual-power jaw crushes fuel costs
Omega Crushing and Screening’splug-in, dual power, electric-drive jaw crusherhas proven to be a fuel-efficient, practical and refined choice fora crushing and screening contractor from Tipperary, Ireland.
Based in Cahir, Co. Tipperary, Quarry Kit Ltd provides contract crushing, screening and heavy haulage services across the province of Munster and further afield. Among the machines on the company’s fleet is an Omega J1065T tracked jaw crusher.Designed with both productivity and simplicity in mind, the J1065T has the distinction of using an electrically- driven crusher unit, feeder and discharge conveyor as opposed to the more common hydraulic design.In addition, the crusher unit’s single drawback rod tensioning system, combined with hydraulic wedge adjustment, make the jaw simple and reliable. While the machine comes equipped with a Stage V/Tier 4-compliant Deutz diesel powerpack, it can also be connected to the power grid and operate without producing any emissions on site.
Impressive fuel savings
The nature of the sites where Quarry Kit Ltd have been using the J1065T has meant that the diesel engineis required for power, rather than the plug-in mains capability. However, even while operating this way, impressive fuel economy has been achieved. Quarry Kit Managing Director Niall Lenihan
explains,“It’s burning between 10 and 12 litres of diesel an hour, compared to other machines I have which burn between 35 and 40 litres an hour. A customer who is using a screener with a four-cylinder engine has told me that the screener is using more fuel than the six-cylinder engine in the Omega”, he says.
This fuel saving does not come at the cost of productivity, however. Niall praises the aggressiveness of the crusher and reports that, working in a limestone quarry, the machine is producing 100mm down at a rate of 240 tonnes per hour. This figure is impressive considering that, according to Niall, other crushers he has operated in the same size class have only achieved figures closer to 180 tonnes per hour. Omega’s principle of simplicity continues with the design of features such as the control panel, and Niall confirms that ease of use is a strength of the J1065T.“It’s a very easy machine to operate–it can be set up, moved, or folded up quickly, then you just press the buttons and away it goes”, he says.
While crushers generally produce quite high levels of noise, Niall mentions that the Omega J1065T impresses in this area. “Compared to other machines, it is very quiet. The engine runs at lower revs, and you can actually talk to someone while standing beside it”, he explains.
