We have concrete experience dealing with:
- Dust and noise emissions
- Atex (Atmospheric explosions) => material
with self ignition
- Materials with high moisture content >15
%
- Freezing material (Minus temperatures
and bad weather conditions)
- Mega-Machines wether it is the size or the
capacity
- sophisticated designs and concepts

Part 3:
Scraper Reclaimer vs Bucketwheel Reclaimer
Presented by Khalid Bhihi Slide
Comparison between Reclaimers and
Bucketweel Reclaimers Mining operation as well as stockpile applications have different requirements:
Mining operation Stockpile operation
Undefined geometry of operating range Defined geometry of op. Range
Practically no space limitation Limited space available
Undefined material lump size Defined material lump size
Manual Operation Automatic operation
Very high output rate (>5.000 t/h) Medium output rate (< 5.000 t/h)
Presented by Khalid Bhihi Slide
High space consumption
in relation to the
stockpile size
Requires more space on
the stockyard (digging
element only at boom
end)
resulting in large unused
areas on the stockyard
Large counterweight,
high wheel loads
No economic way to
cover the stockyard
Presented by Khalid Bhihi Slide
Chaotic stockpile geometry
No chance to reclaim pile
completely
High dynamic loads on the steel
structure caused by periodic
digging action,
resulting in structural failures
later on.
High wear due to high digging
speed (>1,5 m/s)
Presented by Khalid Bhihi Slide
Compact design
No counterweight, less foundation required
Optimum use of available space
If required, stockpiles easy to cover
Presented by Khalid Bhihi Slide
- Smooth operation, as material is gently pushed by
the shovels at low speed
(less material degradation, less noise and
vibrations)
- Low wear due to low chain speed (<0,7 m/s)
- Full automatic operation
- Self-stabilizing design, practically undestructable

Stockpile Geometry Bucket Wheel Scraper Reclaimer
(chaotic) (systematic)
Presented by Khalid Bhihi Slide
Stockpile geometry
of a Bucket Wheel
• High quantities of unreclaimable material
• Trapezoidal shape required
Presented by Khalid Bhihi Slide
Stockpile geometry
of a Scraper Reclaimer
• Stockpile completely reclaimable
• Triangular cross section – best utilization of available area
