The S457 Linear Vibrating Screen is a high-efficiency dry screening machine designed for foundry, mining, metallurgy, and building materials industries, suitable for classification, dewatering, dedusting, and cooling of molding sand, reclaimed sand, and granular materials. Utilizing a dual-shaft inertial exciter + wear-resistant screen body + elastic isolation structure, the S457 delivers directional linear vibration for rapid, uniform material distribution and efficient separation—ensuring high throughput, low clogging, and long service life.

Constructed with a Q345B high-strength steel welded frame, stress-relieved by full annealing, the machine offers excellent rigidity and durability. Screen panels are available in perforated plate, woven mesh, or composite types—adaptable to various particle size ranges. The S457 integrates seamlessly with bucket elevators, cooling beds, belt conveyors, and dust collectors, widely used in resin sand reclamation lines, sand recycling systems, pre-storage classification, and auxiliary foundry equipment—making it a key component in automated and intelligent sand handling systems.

Material Feeding
Feed material is evenly introduced via vibratory feeder, bucket elevator, or screw conveyor. Upon entering the screen box, it rapidly spreads under vibration.

High-Efficiency Linear Vibration, High Screening Accuracy
Frequency 45–60 Hz, adjustable exciting force (15–50 kN), screening efficiency ≥90%, capacity 30–80 t/h—suitable for dry and damp materials, anti-clogging, non-sticking.

Low Noise & Low Vibration Transmission
Rubber or air spring isolation system provides >92% vibration isolation, noise level ≤78 dB(A)—minimizing impact on plant structure.

Modular Quick-Change Design, Easy Maintenance
Quick-clamp or hydraulic tensioned screens—replacement in <25 minutes; external exciters for easy access; standardized fasteners and high part interchangeability.

Smart Control, User-Friendly Operation
PLC + 7" color HMI with manual/auto/test modes; self-diagnosis with Chinese fault alerts; expandable MODBUS RTU/PROFINET for integration with central control systems.

Eco-Friendly Sealed Design, Dust-Controlled
Fully enclosed screen box with sealed covers and viewing windows; optional top dust port for connection to pulse-jet collector, emissions <10 mg/m³—compliant with GB 16297.
