Clay Sand Treatment Regeneration Equipment Set

The Clay Sand Processing Line is a fully automated sand reclamation system integrating spent sand recovery, crushing & screening, cooling & moisture adjustment, mixing, conveying, and storage. Designed for green sand casting processes, it is widely used in foundries producing automotive components, engine blocks, machine tool castings, valves, and agricultural machinery—where high-volume, continuous production is required. Utilizing a "thermal reclamation + moisture control + homogeneous mixing" process, the line enables efficient sand recycling, significantly reducing raw sand and bentonite consumption, improving sand property consistency, ensuring casting surface quality and dimensional accuracy, and supporting green and intelligent foundry development.

With a capacity range of 5–50 tons/hour, the line features a modular design, allowing flexible configuration based on customer plant layout, sand processing requirements (e.g., thermal reclamation), and production needs. It supports standalone operation or full-line integration, seamlessly connecting with molding machines, pouring lines, and shakeout systems to form a complete automated foundry line.

1. Spent Sand Recovery
Function: Collects hot spent sand from the shakeout, conveying it via vibratory conveyor or bucket elevator to the next stage.
Features: High-temperature resistant (≤600°C), wear-resistant, uniform feeding.

Fully Automated, Stable Operation
PLC + HMI + SCADA system enables automatic start/stop, parameter setting, fault alarms, data logging, and remote diagnostics—minimizing manual intervention.

Superior Sand Quality, High Casting Yield
Clean, temperature-stable, moisture-controlled reclaimed sand reduces blowholes, veining, penetration—improving surface finish and yield.

Energy-Saving, Eco-Friendly, Cost-Effective
Energy-efficient thermal reclaimer with waste heat recovery; enclosed structure with pulse dust collector (emission ≤10 mg/m³)—meets national environmental standards.

Modular Design, Easy Maintenance
Independent modules with good fault isolation; quick-change components (bearings, screens, rollers)—short maintenance time, low downtime.

Smart Upgrade Ready
Supports MES/ERP integration, energy monitoring, predictive maintenance, AI-based sand optimization—enabling smart factory transformation.

Safe & User-Friendly
Equipped with emergency stop, overload protection, interlocked doors, dust concentration monitoring—ergonomic design for operator safety.
