As a trusted Eagle Iron Works dealer, NorX has helped countless aggregate producers optimize their operations through advanced water scalping and classification solutions. Our experience with Water Scalping-Classifying Tanks has shown us firsthand how these sophisticated systems can transform production efficiency and product quality.
Core Benefits of Water Scalping-Classifying Technology
The beauty of these systems lies in their triple-function design. Each tank serves as a powerhouse for water removal, precise particle classification, and custom material blending. For aggregate producers seeking to enhance their output quality while streamlining operations, these capabilities prove invaluable.
Understanding the Water Removal Process
The primary function – water removal – sets the foundation for efficient processing. When material enters the system, excess water and fine silts naturally overflow the weirs, creating a more manageable product stream. This initial step proves particularly valuable for operations using Fine Material Washers, as it prevents the loss of valuable sand particles.
For operations running dredging or pump-fed sand plants, these tanks are particularly effective. Their ability to process low-density slurry makes them an ideal match for these challenging applications.
The Science of Hydraulic Classification
The tank’s innovative design features a specialized long, narrow configuration divided into distinct processing stations. As material enters through the feed box, the system creates a calculated upward movement that prevents premature settling of finer particles. This engineering allows for precise separation based on particle size:
• Coarse materials settle in the initial stations
• Medium-sized particles collect in the middle sections
• Fine materials travel to the furthest stations
Each station operates with multiple discharge valves – typically two to four – that respond to material accumulation. When rotating paddles detect sufficient buildup, the valves release a carefully calculated portion to the collecting flume.
Customizable Product Creation
The collecting flume system, featuring up to four distinct cells, enables remarkable blending flexibility:
• Two-cell configurations deliver one controlled and one residual product
• Three-cell setups produce two controlled products plus one residual
• Four-cell arrangements allow for three controlled products and one residual
Achieving Precise Material Specifications
One of the most valuable aspects of these tanks is their ability to create products that consistently meet exact specifications. The system achieves this through precise valve timing control, determining how long each station releases material to the collecting flumes. This level of control means excess material from any station can either contribute to a second specification-grade product or move to the residual stream.
Optimizing Fines Management
The tank’s expansive settling area excels at fines retention. The relationship between surface settling area and water volume determines which particle sizes remain in the product. This gives operators precise control over material composition – a crucial factor in meeting strict product specifications.
Essential Maintenance Guidelines
To maintain peak performance, we recommend:
• Regular inspection of valve operation
• Monitoring of hydraulic systems
• Annual system flush (or every 2,500 operating hours)
• Maintaining proper water volume and specific gravity (1.0-1.05)
Troubleshooting for Maximum Uptime
