WithoutDust Encapsulation

Stockpiling is in most places done

without any dust encapsulation,

which is creating a big

environmental problem


3/29



Even coarse material contains dust


4/29



Stockpile Segregation

Traveling Material becomes

stratified when the conveyor beltis passing over the idlers


5/29




Traveling Material becomes stratified when the conveyor

belt is passing over the idlers

Discharge Difference in velocity will cause large particles to

travel faster (further)


6/29




Traveling Material becomes stratified when the conveyor

belt is passing over the idlers

Discharge Difference in velocity will cause

large particles to travel faster (further) Overrun Larger particles are rolling down

the side of the stockpile


7/29



Stockpile Segregation Degradation

A stock pile can be revitalized through mechanical work mixing using

a wheel loader or a bulldozer.

During this process the product becomes compacted

and degraded by the heavy machinery passing over it

Loading, transportation and discharging the product

Contamination

There is an increased risk that lubricants,

hydraulic oil or grease contaminate the product.

Costs

Penalties/fees Mixing cost

Higher fuel cost

Increased wear

Lost production

How does it work ?

The falling material stream is creating a

downward air flow vacuum


19/29


Customer benefits

Product features Application

Belts from 800 mm (30") to 1200 mm (48") wide.

Material size 0-32 mm (0 to 1-1/4").

Average wear life is at least one year with a feed containing 32 mm material.

Max. 15 cones gives a total chute length approx 17 meters Total weight of approx 2200 kg.

Normally you don't need a chute that extends all the way down to the ground.

You can can also deduct 1 m (3') for the attachment to the conveyor.

Check with the conveyor manufacturer that the conveyor can take the extra weight.
