Exhibiting at SteinExpo 2008 in Nieder-Ofleiden, Germany from 3 to 6 September 2008 for the first time since both companies became part of the Sandvik group, the joint display will feature eight individual machines divided into a pair of fullyfunctioning crushing and screening trains operating in what is Europe’s largest basalt quarry.
The highlight of the joint display will be through crusher trains comprises an Extec E-7 pre-screen feeding to a Fintec 1440 trackmounted mobile impact crusher that in turn feeds an Extec S-5 screen producing three product fractions. The largest model in Extec’s formidable S-Series, the S-7 sets new standards in screening productivity. With a transport weight of 38.2 tonnes, the Extec S-7 is powered by a Deutz BF4M 2012 diesel engine developing 74.9kw. The Extec S-7 will act as a pre-screen coupled to a Fintec 1440 track-mounted impactor. The Fintec 1440 is carried on a manoeuvrable tracked undercarriage and incorporates a Sandvik PR301D impactor with a fluid clutch drive.
This crusher train will be completed by an Extec S-5, the track-mounted mobile machine that redefined screening efficiency with a patented Doublescreen box design, and a range of innovative features that have established theunit as the foremost product in its class. Developed to bring the huge screen throughputs of a static plant to a compact mobile plant, the Doublescreen design employs two independently-adjustable screen boxes to provide a huge screening area that delivers precise material grading control together with massive production levels.
The second of the two joint displays will comprise a Fintec 640 pre-screen feeding an Extec C-12+ track-mounted mobile crusher that precedes a Fintec 542 mobile screen. Working alongside these is a Fintec 1080 track-mounted cone operating in tertiary crushing mode, together with a second Extec S-7 screen configured to produce four precise and high quality product fractions.
The Fintec 542 track-mounted mobile screen is a robust, highly durable machine that is designed specifically for the recycling and contractor markets. It is carried on a heavy-duty tracked undercarriage and incorporates a large capacity two-bearing screenbox with increased screening angle built into the bottom deck. Together with a large screening surface area and long throw on the screenbox, this delivers enhanced screening efficiency and throughout.
