In today’s competitive aggregates market, maximizing product quality while controlling costs and water use is more important than ever. One powerful solution gaining traction across quarries, sand & gravel operations, and mobile processing sites is the Fisher Industries Air Separator—a versatile machine designed to clean and classify material with dry processing technology.
At Mellott, we’re proud to offer both the Fisher 13′ Portable Air Separator and the Fisher Model 76 Portable Air Separator as part of a complete aggregate processing solution.
What Is an Air Separator?
An air separator uses high-velocity air to separate fines from a feed stream of aggregate material. Unlike water-based wash systems, this dry separation approach lets producers remove unnecessary fine particles without water, mud, or settling ponds. The result? cleaner, higher-value products that meet specifications and less reliance on water and wash plants.
Fisher 13′ Portable Air Separator: Heavy-Duty Performance
The Fisher 13′ Portable Air Separator is engineered for high-capacity performance—making it ideal for larger quarries and production operations.
Key benefits include:
- High Throughput & Efficiency
- Designed to handle up to 150 tons per hour of material, the 13′ unit boosts processing capacity without adding water or wash infrastructure.
- Dry Processing Means Water Savings
- By “dry” processing material, you reduce or eliminate your dependence on wash plants which is an advantage in regions where water is restricted or costly.
- Superior Product Quality
- Excess fines are removed efficiently, delivering cleaner material that meets spec and reduces rejected stockpiles.
- Versatility & Portability
- Mobile on wheels and easy to position, the 13′ separator can move where you need it making it ideal for staged jobs or multi-site contractors.
Fisher Model 76 Portable Air Separator: Compact & Cost-Effective
For smaller operations, contract crushing, or localized projects, the Fisher Model 76 Portable Air Separator delivers many of the same advantages in a more economical package.
Why operators love the Model 76:
-
Right-Sized for Smaller Tonnages
Built to effectively separate fines at capacities around 40–60 TPH, this model is perfect for sand, gravel, and small rock operations.
-
Easy Setup & Mobility
Engineered for fast on-site deployment, the Model 76 can be leveled and operational within hours—minimizing downtime and labor costs.
-
Lower Entry Cost
For contractors and smaller sites, its size and price point make it a smart investment for improving product quality without overcapitalizing.
-
Clean, Dry Aggregate Without Water
Like its larger counterpart, the Model 76 excels in dry processing—preserving your water resources and eliminating the need for expensive wash systems.
Benefits That Impact Your Bottom Line
Across both models, operators see measurable value:
🧑🔧 Reduced Operating Costs
Dry air separation lowers water usage, reduces reliance on wash crews, and trims plant energy costs—especially when compared to traditional wash plants.
📈 More Sellable Product
Unwanted fines that previously detracted from your product can now be removed and marketed correctly, increasing revenue potential.
🚚 Portable Flexibility
Whether you’re shifting jobs or adjusting for seasonal workloads, having a mobile air separator means more uptime and less setup hassle.
🌍 Environmentally Responsible
Dry processing helps companies comply with water restrictions, reduce environmental footprint, and avoid silt ponds and runoff challenges.
Is an Air Separator Right for Your Operation?
If your operation deals with fines, needs to produce cleaner aggregate products, or wants to cut water use and processing costs, adding a Fisher Air Separator can be a game changer, especially when matched to your tonnage needs with the 13′ or Model 76 portable units, now IN STOCK at Mellott.
