A new series of shafts screens that can adapt to a range of different working environments and select different types of materials, has been introduced.
The shafts screeners select and crush excavation and demolition materials, asphalt, coal, organic materials, wood, bark and light plastics, and enables products to be re-purposed immediately. MB Crusher says that the most important and useful innovation of its MB-HDS Shafts Screener is that it can transform one material into another at any time.
The shaft screeners are designed to reduce waste and increase the profitability of a construction site. It allows for continuous work on site, obtaining high-quality materials that can be re-used or sold; saving transport, dismantling and maintenance costs.
In addition, the screening bucket allows the rotating shafts to be changed on site. The company’s patented system keeps the rotating supports in place, allowing the rotors to be removed and re-positioned, while the angular alignment is kept in place. The screening bucket is available in four models, with shafts suitable for the different material selection requirements and can be installed on excavators, diggers, mini diggers and loaders (from 5 to 35 t) in order to access and move around work sites, construction sites, areas containing large pipelines, towns or remote agricultural areas.
The rotary shafts have a centralised greasing system and all maintenance tools are located inside a compartment of the shafts screener. An engineered, automated, shock-absorbing hydraulic system reduces the discharge, preventing damage to the engine, transmission components and the machine boom.
“Compact, reliable, sturdy and safe - the MB-HDS units are designed to be multi-purpose and highly versatile as well as being quieter to operate. Making it possible for companies to use them in towns and historic centres, where there are different types of materials that need to be screened but both space and time are limited. The new system reduces noise levels by 40% when processing materials, in accordance with the regulations, thereby eliminating the need for exterior noise-control systems,” explains MB Crusher production director Diego Azzolin.
