Italian mobile crushing specialist MB Crusher unveiled its new generation of shaft screeners at Bauma yesterday, presenting the new MB-HDS as a solution for those who have to process different kinds of waste rubble, which can quickly be turned into re-usable and profitable material.
Launching the new shaft screener at a preview to an exclusive selection of the global press, Diego Azzolin, production director at MB Crusher, told this publication that the speciality of the new range was its ability to adapt to different types of work and different materials.
The new MB-HDS series is radically different from all the other systems available on the market. It can adapt to a range of different working environments and can select different types of materials with unprecedented simplicity and speed, without the need for a specialist or special training. Since 2001, when we patented our first crusher bucket, MB Crusher has evolved while remaining true to its purpose which is: to facilitate the work on site and to make it competitive, self-contained and profitable, Azzolin said.
What users want is a unit that is able to work continuously, without interruptions for maintenance and to facilitate the processing of materials, which can be very expensive. Over the years we have fulfilled these fundamental requirements, with innovative machines which turn waste materials into opportunities, a key element for many companies nowadays.
The new MB-HDS series of shaft screeners are machines that help in overcoming the challenges involved in earth removal, excavation, demolition, recycling, agricultural activities and landscaping, he added. The machines select and crush excavation and demolition materials, asphalt, coal, organic materials, wood, bark and light plastics, enabling products to be re-purposed immediately.
The rotating shafts of the MB-HDS can be easily changed on site in complete safety by just one person in a matter of minutes, Azzolin explained.
“Our patented system keeps the rotating supports in place and the rotors can easily be removed and re-positioned, while the angular alignment is kept in place. For us, having developed this new system represents a breakthrough, and for (users) it means having a construction site that is always working and obtaining high-quality materials that can be re-used or sold, saving transport, dismantling and maintenance costs.
Until now this has been a complex operation, particularly because it is difficult to position the rotating shafts correctly – they must be synchronised with the power transmission systems and the rollers next to them – and because the support bearings must be replaced as well.”
The innovative MB-HDS Screening Bucket is available in four models with shafts suitable for different material selection requirements. The attachments can be installed on excavators, diggers, mini diggers and loaders (from 5-35t)
Also, they have a centralised greasing system and all maintenance tools are located inside a compartment of the screener. However, these are not the only innovations, because the new generation MB-HDS also takes care of the machine on which it is installed. An engineered automated shock-absorbing hydraulic system reduces the discharge so that the engine, transmission components and the machine boom do not suffer any damage, preserving machinery life expectancy and reducing maintenance costs, said Azzolin.
