The new MB-HDS series selects and crushes excavation and demolition materials, asphalt, coal, organic materials, wood, bark and light plastics, and enables products to be re-purposed immediately. It is possible to transform one material into another effortlessly and any time. In fact, with the MB-HDS Screening Bucket one can easily change the rotating shafts onsite in complete safety: just one person can do this in a matter of minutes.
The patented system keeps the rotating supports in place, the rotors can easily be removed and re-positioned, while the angular alignment is kept in place. Until now, this has been a complex operation, particularly because it is difficult to position the rotating shafts correctly (they must be synchronized 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 the different material selection requirements and, as with all MB Crusher machines, they can be easily installed on excavators, diggers, mini diggers and loaders (from 5 to 35 tons) in order to easily access and move around work sites, construction sites, areas containing large pipelines, towns or remote agricultural areas. Changing of the rotary shafts can be carried out anywhere, they have a centralized greasing system, and all maintenance tools are located inside a compartment of the shafts screener.
