Product DescriptionProduct DescriptionProduct Description of Clay Sand Reclamation LineThe Clay Sand Reclamation Line is a highly automated spent sand processing system designed to reclaim used green sand—high-temperature, lumpy, and contaminated—through crushing, screening, cooling, and thermal/mechanical reclamation. It produces clean, temperature-stable, high-performance reclaimed sand for efficient reuse. Widely used in automotive, engine, heavy machinery, valves, pumps, and machine tool foundries, this system is a key component in building green and intelligent foundry operations.Compared to traditional disposal or inefficient reclamation methods, this line achieves over 90% sand reuse rate, significantly reducing raw sand and bentonite consumption, lowering waste disposal costs, improving sand consistency, and minimizing casting surface defects—helping enterprises achieve cost reduction, quality improvement, and environmental compliance.With a modular design and capacity range of 5–60 tons/hour, the system can be flexibly configured based on customer production volume, plant layout, and process needs. It seamlessly integrates with shakeout systems, mullers, and molding lines to form a closed-loop automated sand handling system.Process Flow1. Spent Sand Reception & ConveyingHot spent sand from the shakeout is conveyed via high-temperature resistant vibratory conveyor or bucket elevator to the first stage.A buffer hopper ensures continuous and stable feeding.2. Crushing & Primary ScreeningCrushing: Large sand clumps are broken down by double-roll or jaw crusher.Screening: Coarse impurities (cores, metal fines, clinkers) are removed by drum or inertial screen.3. Fine ScreeningMulti-deck vibrating screens grade sand particles, ensuring uniform size (≤3mm).Oversize material is recirculated or discharged as waste.4. Thermal Reclamation (Core Process)Optional triple/four-drum thermal reclaimer uses indirect heating (gas/electric) to heat sand to 600–700°C, burning off residual organics (resin, carbon, moisture).Reclaimed sand is clean and reactive, with burn-off loss (LOI) ≤0.5%.5. Cooling & Moisture ConditioningHot reclaimed sand is cooled to 40–50°C in a twin-disk or fluidized bed cooler.An intelligent mist humidification system precisely controls moisture content (±0.2%).6. Storage & ConveyingReclaimed sand is stored in an intermediate silo, then conveyed via belt, bucket elevator, or pneumatic system to the muller or molding station.Ensures continuous feeding and stable production rhythm. Key FeaturesHigh Reclamation Rate, Cost SavingsReuse rate ≥90%, replacing 60–80% new sand—significantly reducing bentonite and raw sand costs.Stable Sand Properties, Improved Casting QualityClean, uniform, moisture-controlled sand reduces veining, penetration, blowholes—improving surface finish and yield.Fully Automated & Intelligent OperationPLC + HMI + Remote Monitoring enables automatic control, parameter setting, fault alarms, data logging, and energy analysis.Energy-Saving & Eco-FriendlyEnclosed structure with pulse cartridge dust collector (emission ≤10 mg/m3), noise ≤85 dB(A); waste heat recovery in thermal reclaimer saves >30% energy.Modular Design, Easy MaintenanceIndependent modules; quick-change components (screens, rollers, bearings)—short maintenance time, low downtime.Safe & User-FriendlyFeatures emergency stop, overload protection, interlocked doors, dust monitoring—ergonomic design for operator safety.Main Technical SpecificationsParameterSpecificationCapacityExpandableGreen Sand TypeBentonite-based green sandInlet Temp.≤600°COutlet Temp.40–50°CMoisture Control±0.2% LOIWith thermal reclaimerDust RemovalPulse cartridge filterControl SystemOptional MES/SCADA integrationTotal PowerDepending on configurationWeight35–220 tonsProtection RatingIP54/IP65 for critical partsTypical ApplicationsSand reclamation for automotive engine blocks, heads, transmission casesMass production of large machine tool castings (beds, columns)Spent sand recycling for valve, pump, and fitting foundriesRetrofit projects for outdated sand systemsIntegrated with DISA, KW, Hitachi vertical molding linesQingdao Dingli Machinery Co., Ltd.Qingdao Dingli Machinery Co., Ltd. is a company specializing in the production of casting machinery equipment.
