The new generation of MB Crusher shafts screeners

“With this new machine, we pushed our boundaries.”

With those words, Diego Azzolin, production director at MB Crusher, introduced the company’s new generation of shafts screeners, which were recently launched at bauma 2019.

“The new MB-HDS series is radically different from all the other systems available on the market,” Azzolin said.

“It has been designed to be a real wild card. 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.”

The new MB-HDS shafts screener is able to adapt to different types of work and different materials. It’s the ideal solution, according to MB Crusher, for those who have to process different kind of waste, which can quickly be turned into re-usable and profitable material.

“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.

The new MB-HDS series selects and crushes excavation and demolition materials, asphalt, coal, organic materials, wood, bark and light plastics. As well, it enables products to be re-purposed immediately. 

With the MB-HDS screening bucket, operators may easily, and safely, change the rotating shafts on site with just one person in a matter of minutes.

As the MB Crusher system keeps the rotating supports in place, 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 companies, whether they are big or small, 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,” Azzolin said.

Previously, this was a complex operation, as it is difficult to position the rotating shafts correctly. The shafts must be synchronized with the power transmission systems and the rollers next to them, and the support bearings must be replaced as well.

The MB-HDS screening bucket is available in four models with shafts suitable for different material selection requirements. They can be easily installed on excavators and loaders from 5 to 35 tonnes.

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. 

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 the engine, transmission components and the machine boom do not suffer any damage. This in turn preserves machine life expectancy and reduces maintenance costs, according to MB Crusher.

“The MB-HDS units are designed to be multi-purpose and highly versatile as well as being quieter to operate,” Azzolin said. 

“We’re 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.”
