CDS-1225 Dewatering Screen and Hydrocyclone 60-80 T/H

The CDS-1225 represents CONSTMACH's advanced approach to fine material washing, combining a dewatering screen with a hydrocyclone system to deliver exceptional results in processing materials up to 7 mm. This integrated unit addresses one of the most challenging aspects of aggregate production: retaining valuable micronized particles that would otherwise be lost during the washing process.

What sets this system apart is its ability to recover particles as fine as 90 microns from the wash water. Traditional washing equipment like screw washers or wheel systems simply cannot match this level of efficiency. They allow these microscopic particles to escape with the wastewater, resulting in material loss and inconsistent product quality. The CDS-1225 changes this dynamic entirely. By utilizing hydrocyclone technology, the system creates a centrifugal force that separates fine particles from dirty water before they're lost. These recovered particles are then directed to the dewatering screen, where they're reunited with the washed sand.

The dewatering screen measures 1,200 × 2,500 mm and operates with dual 4.5 kW vibrator motors that generate the precise motion needed to drain water efficiently while retaining the fine fraction. The screen surface features high-grade polyurethane mesh panels that resist wear significantly better than traditional wire screens. This durability translates to lower maintenance costs and fewer production interruptions. When screen panels eventually need replacement, the process is straightforward and doesn't require specialized tools or extensive downtime.

Working in tandem with the screen, the 20-inch diameter hydrocyclone handles the initial separation stage. A powerful 37 kW slurry pump maintains the pressure necessary to create the cyclonic action within the hydrocyclone body. This pressure forces heavier particles toward the outer walls while lighter water moves toward the center and exits through the overflow. The underflow, rich in fine materials, feeds directly onto the dewatering screen.

The production capacity of 60 to 80 tons per hour makes the CDS-1225 suitable for medium to large-scale operations. This throughput range fits well with many concrete and aggregate production facilities where consistent quality matters as much as volume. Projects with strict gradation requirements particularly benefit from this system's ability to maintain specific particle size distributions. When specifications call for particular percentages of material passing certain sieve sizes, having control over the fine fraction becomes critical.

Another practical advantage lies in the moisture content of the final product. Material leaving the dewatering screen contains significantly less water compared to output from conventional washing systems. This drier sand can be stockpiled immediately without the pooling and runoff issues that plague wetter materials. Storage becomes simpler, material handling improves, and the product reaches a usable state faster.

The system's compact footprint and relatively simple maintenance requirements make it an attractive option for operations looking to upgrade their washing capabilities without major infrastructure changes. Regular maintenance focuses primarily on checking pump seals, inspecting the screen mesh for wear, and monitoring vibrator motor bearings. These are routine tasks that plant maintenance crews can handle without specialized training.

For producers aiming to meet demanding project specifications while maximizing material recovery, the CDS-1225 offers a practical solution that balances performance with operational simplicity.
