Visitors to the SteinExpo 2008 exhibition in Nieder-Ofleiden, Germany, Sept. 3-6, 2008, will be treated to a joint demonstration by Extec Screens & Crushers Ltd. and Fintec Crushing & Screening Ltd. highlighting the synergy between the product lines of the two companies, both now part of the Sandvik group. Exhibiting at SteinExpo for the first time since joining the Sandvik group, the companies’ display will feature eight individual machines divided into a pair of fully functioning crushing and screening trains operating in what is Europe’s largest basalt quarry.
Crusher Train
The first of these crusher trains consists of an Extec E-7 pre-screen feeding to a Fintec 1440 track-mounted mobile impact crusher that in turn feeds an Extec S-5 screen producing three product fractions.
The largest model in Extec’s S-Series, the S-7 sets new standards in screening productivity, according to the company. The machine features the same Doublescreen design as the smaller S-4, S-5 and S-6, but boasts a triple-deck configuration together with an additional side conveyor. The Extec S-7 also features a large feed hopper with optional double-deck vibrating grid and a set of extended conveyors.
With a transport weight of 38.2 metric tons, the Extec S-7 is powered by a Deutz BF4M 2012 diesel engine developing 74.9 kilowatts that meet or exceed all known emissions regulations.
The Extec S-7 acts as a pre-screen when coupled with a Fintec 1440 track-mounted impactor. Powered by a fuel-efficient 330 kilowatts Cat C-13 Tier 3-compliant diesel engine, the Fintec 1440 is carried on a manoeuvrable tracked undercarriage and incorporates a Sandvik PR301D impactor with a fluid clutch drive. Fed via a two-deck pre-screen, the crusher features a four hammer open-style rotor with a diameter of 46 inches and a width of 53.2 inches and discharges onto a secondary pan feeder. The plant is also equipped with a primary feeder and a separate two-deck pre-screen.
Featuring a relatively low weight and compact dimensions, the unit has an operating weight of 49.8 metric tons and is 15.5 meters in length in transport configuration - the Fintec 1440 is transportable in a single load, allowing it to be readily moved and redeployed for maximum use. Optional equipment includes a remote diesel and water pump, an over-band magnet for recycling and demolition applications and a dolly chassis for ease of transport.
This crusher train is completed by an Extec S-5, the track-mounted mobile machine with a patented Doublescreen box design and a range of innovative features. 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 is designed to deliver precise material grading control together with massive production levels.
Other S-5 innovations include a low operating height for ease of transportation, hydraulic raising and lowering of the main conveyor and independent drive and control of the two screening decks for optimum control of angle and precise grading.
Quarrying Demonstration
The second of the two joint displays comprises 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 640 is a heavy-duty mobile scalping screen that is designed for optimum maneuverability and ease of transportation. It is powered by a reliable and fuel-efficient Cat diesel engine that meets all known emissions standards. The Fintec 640 features a Hardox steel apron feeder that directly feeds a variable angle, high-amplitude screenbox- designed for maximum screening efficiency in even the most troublesome materials, including boulder clay, mineral ores and concrete and scrap products.
The C-12+ uses Extec’s design and manufacturing expertise to build upon the success of the track-mounted mobile jaw crusher, the Extec C-12. Compact and mobile, the C-12+ is powered by a Cat C-9 engine that meets all known emissions standards and boasts a large feed opening and unique high crushing speed that deliver high outputs and excellent product size reduction for maximum productivity and profitability.
The Fintec 542 track-mounted mobile screen 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, it is designed to deliver enhanced screening efficiency and throughput.
The Fintec 1080 track-mounted mobile cone crusher is the plant of choice for aggregates producers seeking optimum product cubicity and quality, according to the company. Powered by a fuel efficient Cat C-13 diesel engine that meets all known emissions standards, the compact Fintec 1080 incorporates a proven, hydraulically driven C3 cone crusher and employs the CSC (cubical shape crushing) principles developed by Sandvik designed to deliver excellent product shape. A heavy-duty hydraulic cylinder supports the main shaft, facilitating adjustment. A semi-automatic setting regulation system optimizes production while allowing for liner wear, allowing liner changes to be scheduled for reduced downtime.
