At KastRock, our goal is to bring the industry’s best washing and classification solutions to your operation. That’s why we’re proud to offer Eagle Iron Works Double Fine Material Screw Washers , engineered to deliver superior washing, dewatering, and classification for fine materials. Why Choose Double Screw Fine Material Washers? Dual-Screw Efficiency for Demanding Operations Eagle Iron Works designs its fine material washers in single or double screw configurations to handle varying throughput needs. The double screw design is ideal when you require extra washing power and higher capacities without overworking a single shaft. Integrated Functions: Wash, Dewater & Classify These washers perform three essential tasks simultaneously: • Washing: The rotating screws, paired with inflow water, create particle-on-particle motion that removes coatings and fines. • Dewatering: As material is carried upward by the screws, drained water escapes through designed clearance paths, delivering drier product discharge. • Classification: Adjustable weirs allow you to control overflow velocity and separate finer particles when needed. These combined capabilities reduce the need for separate equipment, streamline your plant layout, and simplify logistics. Technical Highlights & Design Features Heavy-Duty Gear Reducer Eagle’s washers incorporate a robust gear reducer with helical gearing and triple-reduction design. This configuration enables operators to fine-tune the shaft speed from full capacity down to as low as 16%, matching performance to feed or mesh demands. Durable Shaft & Wear Components The conveyor shaft is built from heavy one-piece tubing with spiral segments welded in submerged arc fashion. Wear shoes cover the full face of the spiral, protecting against abrasion. Optional urethane wear shoes are available for certain applications. Flexibility via Adjustable Weirs To classify material precisely, Eagle washers feature three adjustable weirs. Whether you need strong retention or a hydraulic split, you can tailor overflow velocity to suit your feed. Configurations & Capacities Eagle offers a range of sizes in both single and double screw designs. Models are available in diameters and lengths to match your output needs, perfect for sand, fines, and delicate aggregates. How KastRock Delivers Value with EIW Washers Reliable Inventory & Quick Turnaround We stock common models and work closely with Eagle’s network to reduce lead times. Our goal is to get your screw washer installed and running with minimal downtime. Installation Support & Best Practices Our service team guides each installation, ensuring proper alignment, weir settings, and startup procedures so your equipment performs at peak capacity from day one. Ongoing Support & Lifecycle Management KastRock doesn’t stop at delivery. We assist with wear-part replacement, performance monitoring, and preventative maintenance to keep your washer in top condition.

As the aggregate industry evolves, sustainability is no longer optional, it’s a competitive advantage. Across the sector, operators are shifting toward electric and hybrid equipment to lower emissions, reduce fuel costs, and build a reputation as environmentally responsible. At KastRock, we’re excited to bring you a used Eagle 1400-OC Electric Portable Plant , a machine that aligns productivity with sustainability goals. Why Sustainable Crushing Matters Today Modern regulations, community concerns, and corporate ESG (Environmental, Social, Governance) goals are pushing aggregate producers to rethink how they power their plants. Some of the drivers include: • Reduced carbon footprint: Electric motors, when powered by clean grids or renewable energy, emit far less CO₂ than diesel systems. • Lower operational costs: Electricity often costs less per horsepower-hour than diesel, and maintenance on electric drives is simpler (fewer fluids, fewer moving hydraulic parts). • Noise & emissions control: Electric plants tend to run quieter and produce fewer exhaust emissions — an advantage in urban or regulated areas. • Future-proofing your investment: As grid infrastructure and clean energy grow, electric plant options will only become more attractive. These themes echo what leading equipment companies are promoting today. For example, our partner Mellott recently published an article on how electric and hybrid crushing and screening machines help producers reduce fuel consumption and greenhouse gas emissions while maintaining performance. How the Eagle 1400-OC Electric Contributes to a Greener Footprint The Eagle 1400-OC (Open Circuit) has features and design elements that support a more sustainable operation without compromising on throughput or robustness. Some of the advantages include: Fully Electric or Hybrid Drive Options The 1400-OC platform can operate in an electric-powered mode (or hybrid) so you can reduce reliance on diesel engines. This directly translates to lower fuel burn and cleaner onsite operations. Efficient Material Handling & Pre-Screening With a 2-step grizzly deck before the impactor, the 1400-OC removes fines early, reducing over-processing and wasted energy. This makes the crushing process more efficient and less wasteful. Rapid Setup & Modularity Its hydraulic legs, well-designed layout, and prewired electrical panels help shrink installation time, which means less idle time and associated energy waste. Durable Design & Component Life The plant’s heavy rotor, replaceable wear components , and modular build help extend service intervals. Less frequent part replacement means fewer manufactured parts in circulation, which supports sustainability through reduced waste. These traits make the Eagle 1400-OC a smart option for operators looking to produce more responsibly, without sacrificing crushing power. Ready for a Smarter, Cleaner Plant? If you want to step into the future of crushing and combine performance, efficiency, and environmental responsibility this Eagle 1400-OC Electric Portable Plant is right for you. Contact us today !

At KastRock, we know that in the aggregate industry, downtime is costly. Every minute a crusher sits idle means lost productivity, delayed schedules, and increased expenses. One of the best ways to minimize downtime is by investing in high-quality crusher parts that are built to last. While lower-cost alternatives may seem appealing in the short term, they often lead to faster wear, more frequent replacements, and greater overall costs. Here’s why quality parts are the smarter investment for your operation. 1. Longer Lifespan and Better Performance Premium wear parts such as jaw plates, liners, and blow bars, are engineered from durable alloys that withstand extreme wear and tear. This means fewer part replacements and consistent crusher performance over time. 2. Reduced Maintenance Costs Cheap parts often require more frequent maintenance and unexpected repairs. By choosing high-quality replacements from a trusted supplier, you’ll save money on labor, reduce the need for emergency service calls, and keep your equipment running smoothly. 3. Improved Productivity and Uptime The reliability of your crusher parts directly impacts your operation’s efficiency. Investing in premium parts reduces the risk of sudden breakdowns, keeping your team focused on production instead of troubleshooting equipment failures. 4. Safety and Peace of Mind Worn-out or poorly manufactured parts can compromise not only your crusher’s performance but also operator safety. With quality components, you minimize equipment stress and create a safer, more predictable working environment. 5. Long-Term Cost Savings While high-quality parts may cost more upfront, they pay off in the long run by lasting longer, reducing downtime, and boosting overall productivity. Think of it as an investment in the success and sustainability of your operation. Partner with KastRock for Reliable Crusher Parts At KastRock, we’re committed to helping aggregate producers maximize uptime and reduce long-term costs with durable equipment and quality parts.

Florida’s sunny skies are famous — but so are its sudden downpours. Between June and October, the Sunshine State enters its rainy season, bringing heavy, daily thunderstorms that can wreak havoc on aggregate production. If you’re in the aggregates, mining, or construction industry, you know how critical it is to keep production moving, rain or shine. At KastRock, we’re dedicated to helping operations like yours stay efficient and profitable — even when the weather doesn’t cooperate. Here’s what you need to know about the challenges of Florida’s wet season and how you can protect your equipment, your product quality, and your bottom line. Florida’s Rainy Season: A Challenge for Aggregate Producers Rainy season in Florida typically runs from June through October, delivering over half the state’s annual rainfall in just a few months. While this is great for tropical plants, it’s not so great for: • Material Handling and Stockpiles Excess moisture increases stockpile weights, impacts flowability, and can cause materials to bind together. Wet aggregates can bridge in hoppers, cause blockages in chutes, and overload conveyors . • Production Downtime Equipment exposed to constant moisture faces higher risks of corrosion , electrical faults, and mechanical failures. Unplanned downtime costs time, money, and lost production. • Product Quality Concerns Too much moisture in aggregates can affect product specifications, create inconsistencies in gradation, and increase drying costs for asphalt and concrete applications. 4 Ways to Protect Your Aggregate Operation in the Rainy Season Here’s how smart producers can stay ahead of Florida’s rainy season: 1. Upgrade to Moisture-Resistant Equipment Modern crushers, screens, and conveyor systems often feature protective coatings and components designed for wet conditions. Equipment with sealed bearings, corrosion-resistant surfaces, and advanced electrical enclosures can help reduce weather-related failures. 2. Implement Proper Stockpile Management • Maintain high, steep-sided stockpiles to promote water runoff. • Use tarps or covers where feasible to limit water infiltration. • Install drainage systems around storage areas. 3. Schedule Preventive Maintenance Routine inspections and maintenance during rainy months can prevent small issues from escalating. Key tasks include: • Checking belts and pulleys for slippage • Inspecting seals and bearings for water intrusion • Testing electrical connections and control panels for moisture damage 4. Monitor Moisture Content Invest in moisture measurement systems to keep tabs on your product. Monitoring allows you to adjust your processing, ensuring product specs remain consistent and compliant.
