Product Summary
The Doebritz Horizontal Vibrating Screen delivers exceptional bulk material classification for heavy-duty industrial processes. Engineered for 200 tons per hour (TPH) capacity, this screener features a dual-motor vibration drive system with adjustable amplitude (5-9mm) and frequency (750-1000 RPM). Certified for ATEX Zone 22 explosive dust atmospheres, the unit handles powders (10-200 mesh), pellets, flakes, and abrasive minerals. An isolation frame reduces dynamic load transmission by up to 92%, protecting downstream equipment and plant structures. Suitable for headroom-limited installations where traditional inclined screens cannot fit.
Why Source Doebritz Horizontal Vibrating Screen
- Superior Screening Efficiency: Linear motion vibration pattern ensures material stratification and throughput maximization, reducing carryover and blinding.
- Heavy-Duty Durability: The screen deck uses abrasion-resistant Hardox 400 plate or PU modular panels, rated for 30,000+ hours of continuous operation.
- Minimal Maintenance & Downtime: Quick-release tensioning system for screen media replacement in under 15 minutes. Outboard bearings use a labyrinth seal and grease purging for contaminant exclusion.
- ATEX Certified Compliance: All electrical motors and grounding systems meet ATEX II 2D Ex tb IIIC Db standards, safe for dust explosion hazards.
- Global OEM Supply Capabilities: Doebritz provides full CAD integration support, custom flange patterns, and modular screening decks (single, double, or triple decks).
Housing & Vibration Engineering
The Doebritz Horizontal Vibrating Screen housing is fabricated from 6-12mm structural steel (S355J2+N) with fully welded stress-relieved side plates. The vibration mechanism uses two contra-rotating eccentric shaft exciters, precision-balanced to ISO 1940 G6.3. Screen body connection points feature high-strength M30 10.9 grade bolts with Nord-Lock anti-vibration washers. The screen deck support crossbeams are tubular design (100mm diameter, 8mm wall thickness) to resist bending fatigue. Vibration isolation springs are progressive-rate rubber-metal compound units, providing 18mm static deflection and transmissibility below 0.15 at operating frequency. Standard models include dust-tight covers with 2.5mm neoprene gaskets and inspection doors.

Heavy-Duty Application Scenarios
Aggregate & Mineral Processing
Sizing of crushed stone, sand, gravel, and ores before storage or washing circuits. The horizontal design allows low-profile integration under crushers or ahead of tertiary screens.
Chemical & Powder Coating Classification
Dedusting of polymer pellets, separating oversize agglomerates from calcium carbonate, titanium dioxide, or pigment powders. ATEX-certified models handle organic dust risks.
Recycling & Waste Processing
Screening of shredded plastics (PET, HDPE), e-waste, or glass cullet. Replaceable wear liners and adjustable amplitude prevent screen damage from irregular shapes.
Food & Feed Grading
Stainless steel 304/316L contact parts for corn, soybean meal, or grain cleaning. Sanitary design with radiused corners and quick-deck tensioning.
Frequently Asked Questions
- What is the maximum feed size this horizontal vibrating screen can handle?
- Doebritz screens accept feed material up to 200mm (8 inches) lump size, depending on deck construction. For larger feed sizes, we recommend a scalping deck above the main screen.
- Can you customize flange dimensions or screen deck configuration?
- Absolutely. As an OEM supplier, Doebritz supports custom inlet/outlet flanges to match your existing ductwork, plus single, double, or triple deck designs with varied mesh openings. Minimum order quantity for custom configurations is 2 units.
- Is the Doebritz screen ATEX certified for gas or dust environments?
- Yes, our standard ATEX offering is II 2D Ex tb IIIC Db for dust atmospheres. For gas explosion risks (Ex e or Ex d), we provide explosion-proof electric motors and spark-resistant coatings. Certification documentation included per unit.
- What is the typical lead time for a heavy-duty horizontal vibrating screen?
- Stock units of single-deck, 1500x3000mm model ship in 4 weeks. Custom engineered units (double-deck, special alloys, or oversized) require 6-8 weeks from order confirmation, including factory load testing.
- How do you ensure dynamic loads do not damage my plant structure?
- Doebritz provides a full dynamic foundation calculation report with each screen. We specify isolation springs, seismic stops, and reaction force data for structural engineers. For suspended installations, we offer reaction bars and cable isolators.
