Volvo Construction Equipment( Volvo CE) reported that net sales in Q2 2017 increased by 36 % compared to the same period in 2016. Net sales in Q2 increased to SEK18 511-million( 2016: SEK13.63-million), while operating income was also strongly up, at SEK2 460-million, more than three times the SEK810-million reported in Q2 2016, equating to an operating margin of 13.3 %( compared to 5.9 %). The second quarter of 2017 saw increased demand in most major markets, while order intake increased by 54 % in Q2 2017 and deliveries were up 49 %, at 17 472 machines. Order intake in China was particularly strong, rising by 221 %, driven by increased demand for SDLG wheel loaders as well as SDLG and Volvo excavators.“ Demand for construction equipment continues to improve in Europe and China, and also a clear recovery in the mining segment in many parts of the world,” said Volvo CE president, Martin Weissburg.
Actom Turbo Machines installed 150MW turbo gensets for a new large open-pit copper mine in Panama’ s Donoso District. This is the company’ s first international contract, secured against tough international competition. Actom Turbo Machines was contracted for the mechanical installation of two Skoda Doosan( Czech Republic) 150MW turbo gensets, each comprising an integrated high- and intermediate-pressure turbine, a low-pressure turbine, a Siemens generator, a radial condenser, and auxiliaries. As the OEM only supplied an Installation Quality Controller, Actom Turbo Machines’ installation crew installed the centreline of the turbo generator sets, starting with the inspection of the civil works, followed by the systematic assembly of the turbo generators in the form of transportable components and sub-assemblies.

Minerals students study processing at Haver & Boecker

Haver & Boecker recently hosted 22 University of Toronto minerals students, giving them a first-hand look at the industry. Haver & Boecker engineers presented on various aspects of vibrating screens and the screening process, and hosted a plant tour to reinforce what students have learnt in class. It is the second year that the company has opened its doors to enhance students’ learning.
Professor Erin Bobicki wanted to give the students a chance to learn from industry experts and to see a full-scale vibrating screen, which cannot be done in a classroom.“ The students now have a much
greater appreciation for screening equipment and the science and engineering that goes into it,” she said.
Dieter Takev, Haver & Boecker’ s vice-president of engineering and technology, and Duncan High, processing equipment technology division manager, walked students through the basics of screening, material sizing, and vibrating screen mechanical performance. Students learnt about types of material and screening equipment, calculations for determining optimum performance, and the mechanical design of different components.
Takev also showed the group how mining and aggregates operations use Haver & Boecker’ s Pulse vibration analysis software, developed by Haver & Boecker specifically to monitor the health of vibrating screens and detect irregularities that would prevent optimum performance.
“ Learning the process through which the screens are made was valuable, as was the opportunity to work with the vibration analysis system,” Bobicki said.“ Probably most of the students would think of vibration analysis as a mechanical engineering task, but the truth is that mining and mineral processing are
very interdisciplinary and you end up touching a variety of functions within the industry.”
One of last year’ s participants was hired by Haver & Boecker, joining their processing equipment technology team after graduation.
“ Our team takes pride in the innovation and testing that goes into each product design,” said Peter Kilmurray, Haver & Boecker vice-president of sales, adding that the company will open the same opportunities to other interested educational institutions.“ We’ re more than willing to spend time introducing future industry leaders to ways they can make a difference in the industry.”
