As a trusted Eagle Iron Works dealer, KastRock regularly helps aggregate producers optimize their Fine Material Washer operations. One crucial aspect we focus on is classification—a process that, when properly managed, can significantly improve your material quality and operational efficiency. Understanding Classification in Fine Material Washers The classification process in an Eagle Iron Works Fine Material Washer is remarkably versatile. By adjusting three overflow weirs, you can precisely control the amount of fine material that exits with the water. Our customers often ask about achieving the perfect balance, and we typically recommend keeping the weirs level for retaining more product-size material. When you need to remove excess fines, simply lower the back weir while raising the side weirs. Water Management: The Key to Optimal Classification Water flow management is critical for achieving the desired classification results. The overflow depth at the weirs directly influences your hydraulic mesh split. Eagle Iron Works provides precision-engineered slide charts to help customers determine the exact water gallonage needed for their specific applications. Fine Material Washer Size Options Eagle Iron Works offers an extensive range of Fine Material Washers to suit various production needs: Single Shaft Models The single shaft lineup includes 22", 24", 30", 36", 40", 48", 50", 54", 66", and 72" options, perfect for standard applications. Double Shaft Models For higher-capacity operations, double shaft models are available in 36", 44", 48", 54", 66", and 72" sizes. Optimizing Your Weir Overflow Settings Achieving the perfect hydraulic mesh split requires precise weir overflow management. Here's our recommended process: 1. Use the provided ruler to measure your weir overflow depth 2. Calculate the washer overflow gallonage using Eagle Iron Works' slide chart 3. Verify your hydraulic mesh split using the reference chart For applications like asphalt, concrete, mason, and golf sand products, we recommend targeting the 150 mesh split point. Remember that proper operation requires at least 50 gallons per minute of fresh water per ton per hour of minus 200 mesh material in the washer feed. Screw Speed: Finding the Sweet Spot The screw shaft's rotational speed plays a crucial role in classification efficiency. Through our experience at KastRock, we've found that slower speeds generally allow finer material to settle in the tub, increasing your saleable product yield. Operating at speeds higher than recommended can create excessive turbulence, potentially causing valuable product-size material to overflow with wastewater. Rising Current Classification Technology Eagle Iron Works Fine Material Washers come equipped with Rising Current Classifiers to enhance material separation. However, if you're experiencing excessive loss of product-size fines in the overflow, they recommend either reducing the water flow to the pool area or temporarily disabling the Rising Current Classifier. Professional Support for Your Operation At KastRock, we understand that every operation is unique. We offer comprehensive support in calculating theoretical product gradations for new applications and can help you fine-tune your Fine Material Washer for optimal performance. Our team of experts works closely with Eagle Iron Works to ensure you receive the most current technical guidance and support. Expert Tips for Maximum Efficiency For optimal results with your Eagle Iron Works Fine Material Washer: • Regularly monitor and adjust weir heights based on product specifications • Maintain recommended water flow rates for your specific model • Keep screw speeds within manufacturer guidelines • Regularly calibrate your Rising Current Classifier settings With proper setup and maintenance, your Eagle Iron Works Fine Material Washer can consistently deliver high-quality products while maximizing operational efficiency.

As a trusted Eagle Iron Works distributor, KastRock has witnessed firsthand how proper sand classification transforms construction materials. Our decades of experience supporting concrete and asphalt producers has shown that achieving precise material specifications isn't just about having the right equipment—it's about optimizing every aspect of the classification process. Understanding Sand Classification Requirements Construction-grade sand demands precise specifications, particularly regarding fine material content. Most concrete and asphalt applications strictly limit the amount of minus-100 and minus-200 mesh materials. While many natural sand deposits and crushed stone sands contain excess fines, including silts, dust, and clay, Eagle Iron Works Classifying Tanks excel at removing these unwanted materials. How Eagle Iron Works Classifying Tanks Operate These advanced classification systems feature six to eleven valve stations, depending on the tank size. Each station incorporates sophisticated paddle sensing devices and hydraulically operated valves, controlled by a bridge-mounted system spanning the tank's length. The classification process follows a natural progression: when sand slurry enters the tank, larger particles settle in the initial stations, while progressively finer materials settle in subsequent sections. The system's intelligent design uses paddle sensors to detect optimal discharge timing, automatically triggering valves through PLC control when material levels reach predetermined points. Optimizing Your Classifying Tank Performance 1. Water Management Fundamentals Proper water flow is crucial for effective classification. Eagle Iron Works recommend following these established guidelines: • Calculate 100 U.S. GPM of water per STPH of silt feed • Plan for 10 U.S. GPM of water per STPH of sand solids feed Water integration occurs through three primary methods: • Initial slurry feed • Rising Current Classifier manifold • Recirculation systems (when necessary) 2. Rising Current Classification Enhancement The Rising Current Classifier (RCC) system represents a significant advancement in classification technology. When installed in the first three stations, RCCs dramatically improve separation efficiency by: • Maintaining smaller particles in suspension • Facilitating precise settling of larger particles • Enabling superior product gradation control For optimal performance, we recommend balancing water distribution between slurry feed and rising current, with approximately 25-33% of total water flow dedicated to rising current operation. 3. Weir Configuration for Peak Performance Proper weir adjustment is essential for achieving optimal classification and silt removal. Eagle Iron Works recommends: • Maintaining level adjustable weirs for balanced overflow • Strategic weir height adjustment for enhanced minus-200 mesh control • Regular inspection of weir settings for consistent performance 4. Paddle Sensor Optimization Based on our extensive field experience, Eagle Iron Works found that paddle height configuration significantly impacts classification efficiency: • Higher settings in the first three stations • Gradually lower settings in subsequent stations • Fine-tuned adjustments based on material characteristics 5. Preventive Maintenance Protocol To ensure continuous, reliable operation, Eagle Iron Works recommends implementing a comprehensive maintenance strategy: • Regular system inspections • Maintaining critical spare parts inventory • Following manufacturer-specified maintenance schedules • Immediate attention to any operational anomalies Ensuring Long-Term Success As your Eagle Iron Works distributor, KastRock is committed to helping you maximize the performance of your classification system. Our technical expertise and dedicated support ensure your Classifying Tank operates at peak efficiency, delivering precisely specified materials while minimizing operational disruptions.
