Crushing & Screening
The J1065T’s 30,000kg (66,139 lbs) weight is also a positive, as it makes transporting the machine easier, particularly when navigating narrow roads in rural areas such as West Cork, where Quarry Kit has several customers. Indeed, it is possible for the company to move the crusher using a three-axle trailer, whereas a five-axle unit is often required for their heavier machinery. The machine’s relative compactness and low weight also mean that road permits will not be required when moving from one location to another, in Ireland or elsewhere.
Finally, Niall praises the after sales support provided by Omega Crushing and Screening, who have proven to be responsive and helpful when needed. For example, when Niall requested that the machine’s feed hopper be widened so it could be fed by a larger excavator, this was promptly taken care of by means of a larger set of hopper doors.
Efficient design
The Omega J1065T is part of a range of crushers produced by the manufacturer, which also includes the wheeled J1065Mand static J1065S models. The ability of the machines to run on either mains or diesel power makes them a versatile option, suited equally to quarry, mining or recycling applications, and allows them to operate indoors or in areas with strict emissions
requirements.While hydraulic systems are prone to contamination, leakages& slowing down in high demand application during a day of operation,the electric components of the Omega range can run efficiently throughout a workday, ensuring fast and productive operation.
All of the models in the range use the J1065 single toggle jaw crusher unit. The J1065 has a large feed opening of 1,000 x 650 mm (39.4 x 25.6”). It is driven by a 90 kW (121 hp) electric motor and uses a simple drawback tensioning system. Some other noteworthy points are the reverse crush, jaw unblock feature, the large jaw ejector cylinder, and the bolted mainframe, which provides strength and durability.
Weighing in at 30,000 kg (66,139 lbs), the J1065T features a 3.8 m3 hydraulic folding, Hardox-lined hopper, a 900 mm (35.4”) discharge conveyor and a 600 mm (23.6”) fines conveyor. The main conveyor can be raised and lowered hydraulically for rebar clearance and can also be fitted with an overband magnet separator. The diesel engine is a six- cylinder Deutz TCD 7.8 L6, which reaches the latestStage V emissions standards using SCR and a DPF. Fuel burn while
working can be as low as 8 litres an hour, ranging up to 12 litres when crushing harder rock types.
