The unit is compatible with excavators with an operating weight ranging from 30 tons (60,000 pounds) to 45 tons (90,000 pounds) and meant for sectors such as in quarries, where you need to treat large quantities of material like coal and phosphate.

Or to move, sift, and aerate tons and tons of earth, such as excavating, earthmoving, and large trenching projects.

But it’s not limited to just these application areas because regardless of the construction site or material, the new MB-HDS523 shafts screener is well-equipped

The MB-HDS523 is an HDS unit with five shafts positioned to ensure a greater production rate and processing speed. The “V Shaft System”’s design creates a simultaneous dual screening effect and increases production.

The concealed comb allows the material to enter and flow through the rotors without jamming.

The unit comes with a removable front upper casing, giving the unit a greater closing angle and increase production.


The largest in the range is also the most powerful: the MB-HDS523 shafts screener is powered by two motors, ensuring consistent and quick performance.

But, power is nothing without adequate durability: the MB-HDS523 screener is solid, durable, and suitable for demanding construction sites and heavy workloads. The parts that are subject to wear are protected by reinforced Hardox steel slab, and the bracket and frame are also thicker.

You might think that equipment of this caliber is demanding to maintain, requiring special maintenance, expensive machine downtime, or that the shafts need to be changed in a workshop. But you would be wrong.

MB Crusher wants to facilitate work on the job site in every aspect, especially when it comes to maintenance. A construction site that’s always functioning is a construction site where the job finishes earlier, saving time and money. The MB-HDS523 shafts screener comes with a centralised greasing system to simplify and speed up maintenance operations.

Much like the others in the range, the shafts are easily switched out: they can be replaced on-site and in a few minutes. The patented system firmly holds the rotating system, and the rotors can be easily extracted and repositioned.
