The new MB-HDS523 screener bucket is designed for a high productivity rate

The Italian manufacturer says the new 3.35 tonne shafts screener bucket is suitable for quarries and large construction sites, in addition to other applications.

It adds that the bucket is designed for sectors where power and sturdiness are essential and this includes quarries where there is a need to treat large quantities of material such as coal and phosphate.

It is also suitable for use where there is a requirement to move, sift, and aerate many tonnes of earth, such as excavating, earthmoving, and large trenching projects. MB Crusher says that the new bucket has "only has one goal: a high productivity rate".
The MB-HDS523 is the only unit in the MB-HDS range with five shafts positioned to ensure a greater production rate and processing speed. The “V Shaft System” is designed to create a simultaneous dual screening effect and increase production.
The bucket's concealed comb is designed to allow the material to enter and flow through the rotors without jamming.

The unit comes with a removable front upper casing to give the unit a greater closing angle and increase production.
The MB-HDS523 shafts screener is powered by two motors to ensure consistent and quick performance. The parts that are subject to wear are protected by reinforced Hardox steel slab, and the bracket and frame are also thicker.

The screener features a centralised greasing system designed to simplify and speed up maintenance operations.
The company comments: "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."
