Cover Story
Manufactured in Northern Ireland, the Finlay range of products is steadily expanding with fuel efficiencies and productivity gains being the main focus of the business. It is one of the latest designs that has joined the Skene fleet and is already making a huge difference in the quarry’s productivity.
The Finlay train consists of a jaw crusher, feeding into a cone crusher which exits onto a tracked stacker. The first machine in the train is a tried and tested J-1480 jaw crusher. This is one of the largest jaw crushers in the Finlay range with an operating weight touching 80 tonnes. The J-1480 is constructed around a heavy-duty chassis incorporating long track frames to provide the machine with a sturdy and steady platform. The rear of the
machine holds a standard 10m3 hopper which can be increased in capacity by a further 2m3 using the hydraulically actuated side extensions. The vibrating pan feeder steadily moves the material over the independently driven pre-screen giving optimum separation of dirt, fines, and difficult materials before the rock enters the 1415mm x 800mm mouth of the crusher. The crusher itself is a Jaques JW55 single toggle unit which is capable of a 750t tonnes per hour throughput in the right material. Thanks to the hydraulic closed size settings (CSS) on the jaw, a consistent material size can be achieved with any alterations in size requirements
instigated quickly and safely.
