Product Overview
This single and double-deck dual-use vibrating screen provides an advanced mechanical classification solution designed to streamline granular separation and eliminate the inconsistencies of manual sieving. Built around a robust welded structural steel chassis and an eccentric vibration drive, the equipment delivers continuous, multi-stage material grading with high mechanical efficiency. By automating the screening process, this system reduces operator fatigue, significantly accelerates sample throughput, and ensures repeatable particle size distribution analysis in fast-paced operational environments.
Engineered primarily for geological exploration, metallurgical processing, chemical synthesis, and coal preparation, this unit easily transitions between pilot-scale laboratory testing and continuous on-site production duties. The adaptable mechanical frame accommodates both single-deck and double-deck screening modes, allowing operators to separate bulk materials into two or three distinct size fractions in a single pass. Whether processing raw geological core samples, crushed minerals, or industrial aggregates, the system maintains steady volumetric flow and sharp cut-point accuracy.
Reliability under demanding industrial conditions stands as the foundation of this equipment. Featuring a precision-angled deck, heavy-duty damping springs, and an adjustable eccentric counterweight mechanism, the unit absorbs high dynamic stresses while protecting surrounding equipment from vibration transfer. The rugged steel screening box resists abrasive wear from high-velocity particles, providing processing facilities with dependable, long-term performance and minimal maintenance downtime.
Key Features
- Dual-Deck Modular Sieve Architecture: Configured with a two-tier screening deck housing 600 x 300 mm sieve plates, the system achieves simultaneous three-fraction material grading while offering the flexibility to run single-deck classification whenever simplified sorting is required.
- Adjustable Eccentric Excitation System: Powered by an integrated vibration motor with twin adjustable eccentric flywheels, operators can fine-tune the excitation force and stroke amplitude between 2 mm and 4 mm to match material cohesion and density.
- Optimized 11.5° Gravitational Deck Incline: The engineered 11.5-degree forward slope utilizes gravity alongside high-frequency kinetic energy (1400 impacts per minute) to ensure uniform material conveyance without blinding or bed compaction.
- Interchangeable Wear-Resistant Screen Plates: Supplied standard with 25 x 25 mm upper and 10 x 10 mm intermediate square-mesh plates, complemented by 6 x 6 mm and 2 x 2 mm drop-in replacement plates for versatile size separation across varying material runs.
- Heavy-Duty Structural Steel Chassis: Fabricated entirely from welded structural section steel, the primary support frame delivers uncompromising torsional rigidity, preventing mechanical fatigue and frame distortion under continuous heavy loads.
- Integrated Multi-Spring Damping Isolation: High-tensile spring dampeners isolate the vibrating screen box from the base frame, absorbing destructive harmonic frequencies, decreasing mechanical stress, and maintaining a low operational noise profile.
- Continuous Uninterrupted Material Feeding: Built for continuous processing runs, the unit accepts bulk raw feeds up to 40 mm at rates from 4 to 200 kg/h, channeling separated fractions directly into dedicated discharge chutes for seamless workflow integration.
- Reliable Electrical Grounding and Operator Safety: Features robust protective flywheel covers, an accessible emergency cutoff pathway, and a comprehensive electrical grounding mechanism to ensure safe operation in conductive, dusty, or demanding industrial plant conditions.
