CSW-60 Screw Sand Washer ( Spiral Sand Washing ) 40-75 m3/h

CONSTMACH's CSW-60 screw sand washer stands as a robust solution for processing fine aggregates in demanding industrial environments. This spiral washing system efficiently handles materials ranging from 0-3 mm to 0-7 mm, making it particularly valuable for concrete production facilities and crushing plants where clean, quality sand is essential. The unit processes between 40 and 75 cubic meters per hour depending on material gradation, offering reliable throughput for medium to large-scale operations.

The CSW-60 features a substantial 600 mm diameter screw housed within a 6-meter-long washing chamber. This configuration provides adequate retention time for thorough cleaning while maintaining continuous material flow. The twin 5.5 kW motors drive the system at a controlled 20 rpm screw speed, ensuring gentle yet effective material handling. This rotational speed strikes a balance between washing efficiency and minimizing aggregate degradation, which is crucial when processing gravel, sand, or crushed stone contaminated with excessive clay and dirt.

Built from heavy-duty steel plate construction, the CSW-60 demonstrates exceptional durability in abrasive washing applications. The reinforced body withstands the constant friction of mineral-laden water and aggregate movement, extending operational lifespan significantly. CONSTMACH's engineering team designed the oil-lubricated gearbox specifically for this application, incorporating a large operating service factor that reduces mechanical stress during continuous operation. This design approach translates to fewer breakdowns and lower maintenance costs over the equipment's service life.

The replaceable rubber paddles represent a practical maintenance feature that directly impacts operational efficiency. These components handle the physical work of lifting and agitating material within the washing chamber. When wear occurs, operators can replace individual paddles without dismantling the entire unit, minimizing downtime. The CSW-60's configuration allows for both single and twin shaft setups, providing flexibility based on specific production requirements and available space.

Water consumption for the CSW-60 ranges from 35 to 55 cubic meters per hour, depending on material characteristics and desired cleanliness levels. This requirement must be factored into plant water management systems, particularly in operations where water recycling is implemented. The washing process separates clay, silt, and other fine contaminants from valuable aggregate, discharging clarified sand suitable for concrete mixing and other applications where material purity matters.

At 5,200 kilograms, the unit requires appropriate foundation support and installation planning. The substantial weight reflects the heavy-duty construction necessary for continuous industrial operation. Proper installation ensures optimal performance and prevents mechanical issues related to misalignment or inadequate support.

CONSTMACH Screw Washers address a common challenge in aggregate processing where raw materials contain excessive fines that compromise final product quality. By mechanically scrubbing and hydraulically separating unwanted particles, these systems upgrade lower-grade materials into specification-compliant aggregates. The CSW-60 model specifically targets operations requiring consistent mid-range capacity with straightforward maintenance protocols. Its accessible design allows maintenance teams to service critical components efficiently, keeping production schedules on track.
