DUSTZEN®
STOCKPILE
Water-dilutable polymer-emulsion technology designed to form a flexible protective crust over open mineral piles—helping resist wind erosion, limit airborne fines and reduce valuable material loss.
Seal the surface while keeping the pile workable.
Open stockpiles are continuously exposed to wind, dry weather, handling and rainfall. DUSTZEN Stockpile wets the surface fines and develops a cohesive polymer network as water evaporates, creating a protective crust without converting the entire pile into a rigid mass.
Wind-Erosion Resistance
Helps prevent loose surface fines from becoming airborne.
Flexible Film Formation
Designed to tolerate normal settling and limited pile movement.
Reduced Material Loss
Helps retain valuable coal, ore, mineral and aggregate fines.
Targeted Surface Treatment
Concentrates treatment on the exposed outer layer of the pile.
Every exposed surface can become a dust source.
Dry fines migrate under wind and handling. Conventional water spraying may provide only short wetting, while repeated oversaturation can create runoff and handling problems.
Surface Erosion
Wind removes the lightest fraction first and spreads dust beyond the storage area.
Material Loss
Loss of fines can reduce saleable yield and change material consistency.
Repeated Wetting
Plain water may evaporate rapidly and require frequent reapplication.
Off-Site Dust
Visible emissions can affect site housekeeping, neighbours and environmental performance.
Four stages from wetting to protective crust
Dilute
Prepare the selected concentration in clean water under gentle agitation.
Cover
Spray the complete exposed surface using overlapping passes and adequate reach.
Bind
The polymer distributes around loose fines and builds inter-particle cohesion.
Crust
As water evaporates, a flexible protective layer develops over the pile.
Match treatment strength to pile duty.
The optimum concentration and application volume depend on material particle size, moisture, slope, porosity, wind exposure, rainfall and the required protection period.
Use the stronger end of the range for fine, dry material, severe wind exposure or longer protection. Higher dilution may suit short-duration control or maintenance coats. Finalise by a controlled site trial.
Active
Stockpile
For piles accessed frequently, apply targeted coats to exposed or newly formed surfaces and renew after material movement.
Seasonal
Storage
Apply a continuous crust over the final pile profile, including crest, slopes and wind-facing surfaces.
Long-Term /
High-Wind
Evaluate a stronger concentration, multiple light coats or increased coverage after confirming drainage and crust integrity.
Build a continuous, inspectable surface crust.
Uniform coverage is more important than heavy local wetting. Treat every exposed face and minimise shadowed or inaccessible areas.
Profile the Pile
Stabilise the pile shape, reduce loose overhangs and identify high-wind faces.
Prepare Solution
Charge clean water first, add DUSTZEN Stockpile slowly and mix gently.
Spray in Passes
Use a cannon, boom or hose to apply overlapping passes from crest to toe.
Allow Drying
Permit film formation without disturbing the treated surface or causing runoff.
Inspect & Repair
Check for gaps, cracks, handling damage and weathered zones; spot-treat as needed.
Confirm crust performance on the actual material.
Recommended Site-Trial Checks
- Complete wetting of crest, slopes and toe
- Crust continuity after drying
- Resistance to wind and natural pile settling
- Behaviour after rainfall and drying cycles
- Runoff, drainage and ponding
- Ease of reclaiming or breaking the treated surface
- Time until spot repair or reapplication is needed
Confirm environmental suitability, downstream process compatibility and material quality requirements before full-scale adoption.
Flexible protection for multiple bulk materials.
Coal & Coke
Open yards, power-plant storage and export-terminal stockpiles.
Ore & Mineral Fines
Iron ore, mineral concentrates, limestone and other exposed fines.
Aggregates & Overburden
Sand, crushed stone, quarry products, soil and overburden mounds.
