The new MB-HDS523 shaft screener is here.

Like the unit’s younger sisters, it’s designed and built to be a real wild card on the job site: the unit adapts to different application areas and selects numerous materials without needing specialized personnel or special training.

TECHNICAL LEVEL ADVANTAGES
✓ It’s the only unit with five shafts positioned to ensure a greater production and processing speed. The “V Shaft System”’s designed to create a simultaneous dual screening effect and increase production
✓ The concealed comb allows the material to flow and enter the shats without blocking or jamming the unit
✓ The shafts screener’s front upper casing can be removed to give the machine a greater closing angle and increase production
✓ It’s powered by two motors to ensure consistent and fast performance

WHAT EXCAVATORS IS THE UNIT COMPATIBLE WITH
The new MB-HDS523 shafts screener bucket is compatible with excavators that have an operating weight of 60,000 to 90,000 pounds.

WHAT JOB SITES CAN IT BE USED ON
The unit is designed for sites where having stronger and tougher equipment is necessary, for example, quarries that treat large quantities of materials such as coal and phosphate. The unit can move, sift, and aerate huge quantities of soil in excavation, earthmoving, large pipeline and road work projects.

WHAT IS THE UNIT MADE OUT OF
The parts subjected to wear are protected by additional Hardox steel slabs; the bracket and frame are also thicker to ensure greater efficiency.

MAINTENANCE EASY
More than easy — it’s effortless!
✓ The greasing system is centralized to simplify and speed up maintenance operations
✓ In a few minutes, the shafts can be changed and replaced directly on site. The patented system keeps the rotating supports firm; the shafts are extracted and repositioned easily

THE SOIL WE LIVE ON IS A NON- RENEWABLE RESOURCE AND MUST BE PRESERVED
Where does soil used on different construction sites around the world come from
✓ From earthworks, to foundations, to trenches
✓ From drilling and consolidation works
✓ From infrastructural work such as tunnels
✓ From removing and leveling earthworks

Different origins but all with one thing in common: they are limited resources. The resource’s constant collecting and consequent deter-ioration make it difficult for the materials to regenerate naturally, needs to be safeguarded.

And the first form of protection is reusing the soil itself, which is a fundamental aspect to avoid altering the environment’s quality.

With the right machinery you:

  • Reduce environmental impact
  • Speed up processing times
  • Improve profitability

Several companies did this by installing one of MB Crusher’s units on their excavator. Their decision to protect the environment and carefully manage excavated materials also allows them to multiple the requests to continue their work on numerous projects.

SAND
Quillagua, a small Chilean town in the Antofagasta province, is considered the driest location in the world, making it inhospitable. They used an MB-S18 screening bucket to screen sand and reuse it to cover the solar panels’ cables. Now, the citizens of the town can communicate with the rest of the world.

Reusing the sand made it possible to:

  • Avoid polluting the construction site with materials from other areas
  • Save money by repurchasing new material

ROCKS
In Croatia, a company that has several working construction sites solved their problem regarding separating rocks from soil using an MB-S18 screening bucket, which can be transported with the excavator and used on any construction site.

By separating rocks from soil, you can:

  • Maintain the soil’s quality and functionality
  • Recover the rock and soil

Before the solution, the company took the excavated soil to another site and dealt with the expensive management and transportation costs.

POLLUTED SOIL
In China, a company used an MB-HDS320 shaft screener and obtained excellent quality soil, which they immediately reused on site.

Moving polluted soil lets you:

  • Mix it with other products and neutralize the pollution
  • Save a lot of money regarding disposal costs
