Sizing a sieve separator comes down to matching screen diameter and power to your actual throughput, and mesh size to your material's particle size distribution — treating "a sieve is a sieve" is a common way a screening station ends up undersized for the volume it's actually asked to handle.
DY Series Model Range
| Model | Screen Diameter (mm) | Effective Screening Area (m²) | Power (kW) |
|---|---|---|---|
| DY-400 | 400 | 0.10 | 0.25 |
| DY-600 | 600 | 0.25 | 0.55 |
| DY-800 | 800 | 0.45 | 0.75 |
| DY-1000 | 970 | 0.68 | 1.1 |
| DY-1200 | 1170 | 1.00 | 1.5 |
| DY-1500 | 1470 | 1.60 | 2.2 |
| DY-1800 | 1770 | 2.35 | 3.0 |
| DY-2000 | 1950 | 2.85 | 3.7 |
Effective screening area — not screen diameter alone — is what actually determines throughput capacity. Two screens with similar outer diameters can have meaningfully different effective areas depending on deck construction, which is why sizing off diameter alone can under-provision a line.
Mesh Range and Deck Configuration
- Mesh range: 0.075mm–10mm across the DY series
- Deck layers: 1 to 3, depending on whether you need a single accept/reject cut or classification into multiple size fractions
- Vibration speed: 1,450 RPM
- Screen change time: under 5 minutes
A single-deck configuration suits a simple oversize-removal application. Multi-deck configurations (2–3 layers) suit applications needing classification into distinct particle size fractions in one pass, rather than running material through multiple separate screening steps.
Screening Principle Options
Beyond the standard rotary vibrating configuration (DY), the range includes ultrasonic screening (DYC, 25–38kHz, for fine powders below 100 microns or oily/sticky materials), tumbler screening (DYB, 90–95% accuracy), and linear vibrating screening (DZSF, for larger-area, multi-grade applications). The model number and screening principle need to be specified together — a DY-1200 rotary screen and a DYC-1200 ultrasonic screen serve very different materials despite similar frame sizing.
Power and Utility Requirements
Power ratings scale from 0.25kW on the smallest DY-400 to 3.7kW on the largest DY-2000 — a straightforward function of screen size and vibration mass. Confirm your available power supply and any area classification requirements (for combustible dust environments) against the specific model before finalising.
What to Send With Your Enquiry
A complete sieve separator specification starts with: material characteristics (particle size distribution, moisture content, oiliness or stickiness, bulk density), required throughput rate, target mesh size or cut-point, whether single or multi-fraction classification is needed, and any contamination or oversize risk specific to your upstream process. Review the full Sieve Separator range before finalising your screening station.
