The L32 Series Sand Reclamation Drum is a high-efficiency non-vibrating shakeout machine designed for complex-shaped, thick-walled castings and high-bond-strength molds (e.g., resin sand, sodium silicate sand). Utilizing a rotating drum + internal breaker lugs + continuous conveying system, the L32 achieves gradual mold breakdown through free tumbling and casting-to-casting impact—ideal for large, irregular, or fragile castings that are difficult to clean via vibratory methods.

Constructed from a cylindrical drum rolled from Q345B high-strength steel, externally reinforced with wear-resistant rings and rubber damping layers, and supported by four sets of idler rollers for smooth operation. Internally, replaceable high-wear-resistant breaker lugs are evenly arranged to enhance lump crushing. Spent sand exits through perforated drum walls into a belt conveyor or bucket elevator, while castings discharge continuously at the outlet for cooling or cleaning. The L32 is widely used in shakeout for valves, pumps, marine castings, heat-resistant alloy parts, and other complex or vibration-sensitive components.

Casting Feeding
Castings with sand are fed into the drum inlet via apron conveyor, forklift, or robot arm, smoothly entering the drum through a feeding chute.

Non-Vibrating Design, Protects Casting Surface
Eliminates risk of cracks or deformation from high-frequency vibration—ideal for thin-walled, fragile, or precision castings requiring gentle shakeout.

High Adaptability, Handles Complex Castings
Capable of processing irregular castings up to 3 m long and 5 t in weight; excellent performance on high-bond sands like resin and water glass, sand removal rate ≥90%.

Continuous Operation, High Automation
Continuous feeding, tumbling, and discharging—capacity 10–25 molds/hour; integrates seamlessly with conveyors, elevators, and cooling beds for full automation.

Modular Design, Easy Maintenance
Bolt-on breaker lugs—replacement in <2 hours; removable roller assemblies for easy service; standardized fasteners, high part interchangeability.

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

Eco-Friendly, Low Noise, Dust-Controlled
Fully enclosed structure with sealed inlets/outlets and top dust port; connects to pulse-jet collector, emissions <15 mg/m³—compliant with GB 16297.
