Product Description
Product Description
Product Description of Clay Sand Processing Line
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.
System Components & Process Flow
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.

Features: High-temperature resistant (≤600°C), wear-resistant, uniform feeding.
2. Crushing & Screening
Equipment: Roll crusher + drum screen/inertial screen
Function: Crushes lumps to ≤3mm and removes cores, metal fines, sintered clinkers—ensuring clean sand grains..
Efficiency: Screening efficiency ≥95%, impurity removal >98%.
3. Thermal Reclamation System (Optional)
Equipment: Triple/Four-drum thermal reclaimer
Function: Indirectly heats sand to 600–700°C (gas/electric) to burn off residual resin, carbon, and organics—restoring sand activity and improving reuse quality.
Benefits: Burn-off loss ≤0.5%, replaces 30–70% new sand—significantly reducing material costs.
4. Cooling & Moisture Adjustment
Equipment: Twin-disk cooler + mist humidification system
Function: Cools hot sand (≤120°C) to 40–50°C and precisely controls moisture (2.5–3.5%) via multi-point mist spraying—preventing casting defects caused by overheated sand.
Control: PLC monitors sand temperature and humidity in real-time, automatically adjusting cooling air and water flow.
5. Sand Mixing System
Equipment: High-speed twin-roll muller or continuous mixer
Function: Blends reclaimed sand, new sand, bentonite, coal dust in precise ratios to produce stable green sand.
Uniformity: Mixing homogeneity ≥98%, meeting high strength and permeability requirements.
6. Sand Conveying & Storage
Equipment: Belt conveyor, bucket elevator, sand silo, pneumatic conveying (optional)
Function: Transports mixed sand to molding station hoppers or intermediate silos for continuous feeding.
Layout: Customizable "straight", "U-shape", or "tower" configurations based on plant height and workflow.
Key Features
Fully Automated, Stable Operation
PLC + HMI + SCADA system enables automatic start/stop, parameter setting, fault alarms, data logging, and remote diagnostics—minimizing manual intervention.
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.
