The user’s guide to choosing a screening bucket or shafts screeners

19-08-2020
  • To separate the fine from coarse material?
  • To process wet material?
  • To clean sandy beaches?
  • To screen material to specific sizes?

There’s a piece of equipment suitable for every step of the operation, one that gets the job done in less time and doesn’t waste money.

So, what do you need to know to choose the best option for you?

Understand:

  • What kind of job is it?
  • What is the desired goal and do you need it?
  • What type of material do you need to process?

​We compared the MB-S screening bucket and the MB-HDS shaft screener to understand the uses and strengths of each unit on job sites with different materials.

SAND

MB-HDS320

Separating sand from rocks during a trench excavation job. This unit was chosen because:

  • The fine material is screened directly into the trench
  • It can process large amounts of material

MB-S14

Separating trash from the sand on a beach. Why should you use this screener?

  • Precision. By choosing the right size sieve, you will have clean material, while all of the larger material will remain in the basket. 

DIRT / TOPSOIL

MB-HDS

How to extend a utility line from a preexisting prison to a new building?  By digging a trench and using a shafts screener. Why did they choose this unit?

  • For the rapidly rotating shafts.
  • To break apart clumps of dirt. 
  • To process humid or wet soil.

MB-S

Before laying a grass layer on a soccer field, you need to create a fine dirt base. The screening bucket makes any job easier; the only requirement is choosing the right size sieve, which allows you to attain:

  • Consistent material.
  • High quality sifted material

STONES / INERT MATERIAL

MB-HDS

Recycling demolition waste material. In this example they used a shafts screener because they needed:

  • a high production rate
  • to finish the job quickly.

MB-S

Separating fine from the coarse material to build a new railroad network. In this scenario the trommel screening bucket worked because: 

  • They needed homogenous material, and this was obtainable only by using the MB-S screening bucket.

There are also materials that can only be processed by a specific unit.

COMPOST AND BRANCHES

The MB-HDS shafts screener easily aerates and breaks up the material, even if the it is wet or compacted. The same goes for twigs and scrubs that are crushed down and processed.

ABRASIVE MATERIAL

Abrasive material can excessively wear out the shafts of a MB-HDS shafts screener. This is why an MB-S screening bucket would be better suited to separate iron scraps, because the material stays in the basket, while the dirt / dust / flakes fall through.
