L12 Stationary Vibrating Sand Separator

The L12 Series Fixed Vibratory Shakeout Machine is a high-efficiency mold-breaking and sand-separation system designed for small-to-medium foundries, suitable for green sand, furan resin sand, alkaline phenolic sand, and other molding processes. Utilizing a dual-shaft inertial exciter + frame-type elastic support structure, the L12 delivers controlled directional vibration to rapidly break down cooled molds and efficiently separate castings from sand—ensuring smooth casting discharge and continuous sand flow, significantly improving cleaning efficiency.

Constructed with a fully welded Q345B high-strength steel frame, the machine offers excellent rigidity, fatigue resistance, and long service life. Equipped with replaceable wear-resistant screen plates (perforated or woven mesh), it effectively separates large sand clumps from fines while protecting castings. The L12 integrates seamlessly with apron conveyors, bucket elevators, magnetic separators, and cooling beds—forming a complete reclaimed sand recovery and casting handling system, widely used in automated shakeout operations for engine blocks, transmission housings, pumps, and valves.

Mold Feeding
Molds with castings are fed into the inlet zone via manual cart, robot arm, or roller conveyor, smoothly transitioning onto the vibrating screen surface, ready for shakeout.

Dual-Shaft Inertial Excitation, High Efficiency
Adjustable exciting force (20–60 kN), stable frequency, short shakeout time (30–90 sec/mold), sand removal rate ≥95%—reducing downstream manual cleaning workload.

Robust Structure, Wear-Resistant
Frame made of Q345B high-strength steel with stress-relief annealing; screens use NM400 wear-resistant steel or stainless woven mesh, lifespan ≥8,000 hours; overall design life ≥10 years.

Elastic Support, Smooth Operation, Low Noise
Rubber springs or composite isolators provide >90% vibration isolation, noise level ≤80 dB(A)—improving workshop environment and meeting national environmental standards.

Modular Design, Easy Maintenance
Quick-release screen panels—replacement in <30 minutes; external exciters for easy lubrication and inspection; standardized components with high interchangeability—reducing maintenance costs.

Smart Control, User-Friendly Operation
PLC + color touchscreen with manual/auto/test modes; self-diagnosis with Chinese-language fault alerts; expandable MODBUS RTU / PROFINET for seamless MES integration.

Eco-Friendly, Dust-Controlled
Optional top dust hood + pulse-jet collector captures dust during shakeout, emissions <15 mg/m³—compliant with GB 16297 "Comprehensive Emission Standards for Air Pollutants".
