MB Crusher introduces the MB-HDS523 shafts screener

The unit is compatible with excavators with an operating weight ranging from 60,000 to 90,000 pounds.


MB Crusher, Reno, Nevada, has introduced the MB-HDS523 shafts screener to its MB-HDS line, which the company says is designed to increase productivity on the job site.

According to the company, 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 where power and sturdiness are essential, such as in quarries, where you need to treat large quantities of material like coal and phosphate.

The MB-HDS523 can also be used to move, sift, and aerate soil in excavating, earthmoving and large trenching projects. Described by MB Crusher as “the only HDS unit with five shafts positioned to ensure a greater production rate and processing speed,” the MB-HDS523’s contains a V Shaft System that is designed to create a simultaneous dual screening effect and increases production.

The unit features a concealed comb that allows the material to enter and flow through the rotors without jamming. It also comes with a removable front upper casing, giving the unit a greater closing angle and increase production.

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

In addition to power, the company says the unit is also durable. Suitable for demanding construction sites and heavy workloads, the parts of the MB-HDS523 that are subject to wear are protected by reinforced Hardox steel slab, and the bracket and frame are also thicker, making it a well-performing machine.

To facilitate work on the job site in every aspect, especially when it comes to maintenance, the company says the shaft screener comes with a centralized greasing system to simplify and speed up maintenance operations. Much like other units in the range, the shafts are easily switched out and can be replaced on-site and in a few minutes.
