Product Overview

Vibrating Screens are versatile screening solutions designed for precise classification and separation of bulk materials across industries such as mining, aggregates, recycling, and chemical processing. Built to handle dry, wet, or semi-solid substances, these screens deliver consistent performance in sorting materials by size, density, or composition. With robust construction and customizable configurations, they serve as a cornerstone for efficient material handling systems, aligning with GB/T standards for reliability and safety.

Key Features & Benefits

1. Adaptable Screening Performance
   • Accommodates materials ranging from fine powders (<0.1 mm) to coarse aggregates (up to 300 mm).
   • Adjustable vibration amplitude (2–10 mm) and frequency (700–1500 RPM) for optimized separation accuracy.
2. Durable Structural Design
   • Screen decks fabricated from high-tensile steel plates compliant with GB/T 24857, ensuring resistance to deformation under dynamic loads.
   • Welded joints adhere to GB/T 36865-2018 Section 6.2.8 standards for strength and fatigue resistance.
3. Low-Maintenance Operation
   • Grease-lubricated, sealed bearings (IP65 rating) minimize downtime in dusty or humid environments.
   • Modular screen panels allow rapid replacement without disassembling the entire frame.
4. Energy Efficiency
   • Drive power calculated per GB/T 36865-2018 Appendix B.2 principles, with motors ranging from 1.5–22 kW based on screen size and load.

  • Length: 1.5–6.0 m, customizable for specific throughput needs.
• Frame Construction:
  • Sideplate thickness: 6–20 mm (selected per material impact severity).
  • Dynamic load capacity: Up to 15 t/h per m² of screening area.
• Deck Inclination: Adjustable between 15°–25° to balance processing speed and separation precision.

Vibration System

• Exciter Type: Dual eccentric shaft (standard) or electromagnetic drive (for fine-tuning).
• Amplitude & Frequency:
  • Amplitude range: 2–10 mm (mechanical adjustment via counterweights).
  • Operational frequency: 700–1500 RPM, synchronized for minimal harmonic distortion.
• G-Force: 4.5–7.0 g, optimized to prevent material blinding or screen clogging.

Screening Media Options
