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


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)


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


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)


Compact design

No counterweight, less foundation required

Optimum use of available space

If required, stockpiles easy to cover


- 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)


Stockpile geometry

of a Bucket Wheel

• High quantities of unreclaimable material

• Trapezoidal shape required


Stockpile geometry

of a Scraper Reclaimer

• Stockpile completely reclaimable

• Triangular cross section – best utilization of available area
