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. 

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.

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. 

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. 

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. 

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. 

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.

Our service team guides each installation, ensuring proper alignment, weir settings, and startup procedures so your equipment performs at peak capacity from day one.

KastRock doesn’t stop at delivery. We assist with wear-part replacement, performance monitoring, and preventative maintenance to keep your washer in top condition.
