Single-deck Vibration Sifter, Doebritz Screening Classifier, Stainless Steel 304 / 2-100 Mesh / ATEX Certified
Doebritz supplies heavy-duty Single-deck Vibration Sifters for powders, granules & flakes. Stainless steel 304, ATEX certified, CNC precision screening from 2 to 100 mesh. OEM ready.
Product Summary
Doebritz Single-deck Vibration Sifter delivers high-capacity separation for bulk solids: from coarse granules (≥2 mesh) to fine powders (≤100 mesh). Built with a robust stainless steel 304 contact part, ATEX certified for explosive dust atmospheres (Zone 21/22). Features a unique bouncing ball anti-blinding system, ensuring continuous throughput up to 15 t/h (depending on mesh size and material density). Ideal for industrial powder coating, food ingredients, chemical additives, and mineral powders.
Why Source Doebritz Single-deck Vibration Sifter
- Superior Screening Efficiency: Patented eccentric vibration motor generates 3D elliptical movement, achieving >95% separation accuracy with minimal peaking or blocking.
- Global OEM Supply & Customization: Doebritz supports non-standard flange drilling, inlet/outlet orientation, and sanitary grade polishing (Ra ≤ 0.4μm) for food/pharma applications.
- ATEX Certified & Explosion-Proof: Full Ex II 2D T4 certification, with antistastic screen cloth and grounded housing – safe for combustible dusts like aluminum powder, sulfur, or organic pigments.
- 5-Year Structural Warranty: All welds and housing frames are CNC laser-cut and robot-welded, eliminating stress points. Quick-release clamps allow <15 min screen changeover.
- Just-in-Time Delivery: Doebritz stocks standard units (450mm, 600mm, 900mm, 1200mm diameter) with 15-day lead time. Custom orders ship within 4 weeks.
Housing & Rotor Engineering
The Doebritz Single-deck Vibration Sifter features a fully welded stainless steel 304 (or 316L) housing, polished internally to avoid material retention. The single-deck design integrates a tapered frame with a silicone gasket seal – prevents dust leakage even under positive pressure up to 0.5 bar. Screen tensioning is achieved via circumferential toggle clamps with torque indicators, ensuring uniform mesh stretching. The vibration motor (customizable from 0.2kW to 3.7kW) is flange-mounted with outboard bearings, isolated by heavy-duty rubber springs. An optional inspection window with LED light allows real-time monitoring of the screening surface without stopping production.

Heavy-Duty Application Scenarios
Pneumatic Conveying Systems (Dilute & Dense Phase)
Installed downstream of rotary airlocks or mixers, the Doebritz sifter removes oversize contaminants or agglomerates from material flow without interrupting pressure differential. The reinforced deck handles pressure spikes up to 0.7 bar – ideal for closed-loop conveying.
Silo Discharging & Pre-Screening
Positioned under storage silos or hoppers, the single-deck sifter protects downstream milling, blending, or packing equipment. It handles direct gravity-fed loads up to 3 tons per hour per 600mm diameter, with optional quick-change cartridges for grade switching.
Dust Filter Collectors & Product Recovery
In recycling loops (e.g., powder coating overspray, plastic regrind), the Doebritz vibration sifter separates reusable fines from foreign particles (metal chips, paper labels). The low-profile design fits under 1.8m ceilings.
Frequently Asked Questions
- What is the standard lead time for a Doebritz Single-deck Vibration Sifter?
- Standard models (450mm/600mm/900mm diameter) ship within 15 working days after order confirmation. Customized specifications (316L, FDA-grade seals, special mesh) require 20-25 days.
- Can I order a sifter with non-standard inlet/outlet flange drilling?
- Yes – Doebritz provides custom drilling patterns (ANSI #150, DIN PN10, JIS 10K, or customer drawings). Minimum order quantity for custom flanges is 2 units.
- Is this sifter ATEX certified for dust explosive environments?
- Absolutely. The Doebritz Single-deck Sifter carries ATEX II 2D T4 certification (certificate number: DZB-ATEX-2422). All components including motor, seal, and screen are antistatic and spark-resistant.
- What is the maximum operating temperature?
- Standard silicone seals allow continuous operation from -20°C to +120°C. For hot materials (up to 220°C), we supply a high-temp version with Viton seals and a thermally decoupled motor mount.
- Does Doebritz offer OEM manufacturing with my brand?
- Yes – we are a professional OEM partner for global valve & processing brands. We offer housing color customization, laser-engraved brand plates, and dedicated production lines for batch orders over 50 pcs/year.
