MB Crusher's new five-shaft screener bucket delivers high productivity in earthmoving and quarry applications

MB Crusher has expanded its MB-HDS range with the MB-HDS523 shafts screener bucket for earthmoving and quarry applications. The unit is compatible with excavators with an operating weight ranging from 30 tons (60,000 pounds) to 45 tons (90,000 pounds) and features five shafts positioned to ensure a greater production rate and processing speed. 

The largest shafts screener in the range, the MB-HDS523 is specifically designed to maximize results. The V-shaft system design creates a simultaneous dual screening effect while the concealed comb allows the material to enter and flow through the rotors without jamming. The unit also comes with a removable front upper casing, giving it a greater closing angle and increased production. 
 
Maintenance is also a priority, and wear parts are protected by reinforced Hardox steel slab, with a thicker bracket and frame. The MB-HDS523 shafts screener comes with a centralized greasing system to simplify and speed up maintenance operations, and the shafts 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.
