Continuing from yesterday’s post on Bauma (April 19-25 in Munich), International Mining has even more lined up for its special April article on the event. This includes Tenova Takraf’s new generation of mobile crushing systems, ITT Water & Wastewater’s two-stage Flygt pump, SSAB’s free welding handbook, Grindex’s new Master SH pump, Pilot Crushtec’s Twister VSI crushers, Derrick Corp’s Stack SizerTM and Cummins’ V-18 configuration QSK78 engine.
Takraf’s latest technical developments of mobile crushing plants have been manufactured with large scale open-pit mining projects in mind. They are of particular use in coal mines where seams can be extracted along straight and extended benches. The company recently supplied and commissioned a 12,000 t/h mobile crushing plant for a coal mine in northern Queensland, Australia. The unit has a slewable superstructure and discharge boom conveyor that can be positioned at different angles to the mining face, providing operational flexibility.
ITT’s new two-stage 2600 series Flygt pump, the 2660 ST, is the seventh-biggest model of the series and can be used in a broad range of applications within mining. The pump is based on the design of the 2600 series and has a zero leakage ‘Active Seal’, which contributes to longer intervals between oil changes and longer maintenance intervals.
The first edition of the SSAB welding handbook was so popular that several reprints were required to satisfy demand. A great deal has happened in the field of materials in the meantime, including the introduction of new steel types. So SSAB has taken the opportunity to revise and expand the manual. Daniel Stemne has compiled the new revised edition of the classic SSAB welding handbook, which will be available at the company’s booth during the show.
Grindex’s new drainage pump has been designed to deliver water up to over 80 m in one single step, made possible due to the double stage impellers and design. The Master SH pump can be used in deep excavations where high head pumping is common. It comprises all the features known from other Grindex dewatering pumps, with tripled wear resistance compared to earlier pump generations.
Over 50 of Pilot Crushtec’s tracked TwisterTrac VSI crushers and over 500 static Twister VSI crushers are in operation around the world. The crushers use two variations of crushing. The first involves vertical shaft impact crushing, with rock being fed into a table type rotor which then accelerates and discharges the rock at high speed, against steel anvils in the crushing chamber. The impact of the rock hitting the steel anvils induces fractures, causing the rocks to break apart. The second variation called vertical shaft autogenous (VSA) crushing sees the rock being fed into a multi-port rotor which accelerates and discharges the rock at high speed against a rock filled crushing chamber. The impact of the rock on rock fractures, breaks and shapes the rock.
Derrick’s Stack Sizer is used for fine particle wet screening. It consists of up to five individual screen decks positioned one above the other and operating in parallel. The sizer can also be fitted with urethane screen surfaces.
The QSK78 engine will lead the Cummins line up at Bauma. The V-18 configuration QSK78 was the first engine to bring a 2,610 kW power capability to mining haul trucks operating at high altitudes. It was also the first engine of its size to feature a full-authority electronic management system, enabling engine parameters to be customised to precisely match the duty cycle of the equipment. The company’s display will also feature the EliminatorTM self-filtration system (featured in IM’s upcoming Maintenance feature in March).
