Product DescriptionProduct DescriptionProduct Description of Resin Sand Production LineThe Resin Sand Production Line is a fully automated system integrating sand pretreatment, precise metering, high-speed mixing, cooling & screening, conveying, and central control, specifically designed for producing high-quality chemically bonded no-bake resin sand. It is widely used in automated molding and core-making processes for large steel/iron castings, wind power, shipbuilding, rail transit, construction machinery, valves, metallurgy equipment, etc. Utilizing an advanced "sand pretreatment → precise ratio → efficient mixing → rapid cooling → online inspection" process, the line ensures stable sand properties, excellent flowability, and high strength—meeting the dual demands of sand quality and production efficiency in modern foundries.With a capacity range of 2–30 tons/hour, the line supports continuous or batch operation, and can be flexibly configured as standard, explosion-proof, stainless steel, or intelligent unattended models—suitable for new foundries, green smart factory upgrades, or retrofit projects. It seamlessly integrates with automated molding lines, central sand supply systems, and MES/ERP platforms to build a digital, intelligent foundry sand center.Process Flow1. Sand Pretreatment SystemBase sand (washed, calcined, or reclaimed sand) is conveyed via bucket elevator or pneumatic system to a dry sand silo, ensuring stable temperature (25–35°C) and moisture ≤0.2%.Optional sand temperature regulator maintains process stability across seasons.2. Precise Metering SystemBase sand is metered dynamically via frequency-controlled screw feeder + high-precision load cells (accuracy ±0.5%).Resin (furan, alkaline phenolic, PU, etc.) and hardener (organic sulfonic acid, ester, etc.) are dosed by corrosion-resistant metering pumps at preset ratios (accuracy ±1%).3. High-Speed Mixing System (Core Process)Sand, resin, and hardener are fed into a twin-shaft counter-flow mixer or planetary high-speed mixer, where thorough blending occurs within 15–45 seconds.Mixing blades made of wear-resistant alloy steel (NM400) or ceramic coating ensure homogeneity ≥98%, free from "raw spots" or lumps.4. |Cooling & Screening SystemHot resin sand is cooled to ≤45°C in a twin-disk or fluidized bed cooler to prevent premature curing.A multi-deck vibratory screen removes lumps and impurities, ensuring free-flowing sand.5. Finished Product Conveying & StorageQualified resin sand is conveyed via belt conveyor, bucket elevator, or pneumatic system to molding station hoppers or central sand silos.Supports multi-route distribution and timed feeding for continuous, stable production.6.Intelligent Control SystemIntegrated PLC + 10" HMI enables multi-recipe storage, automatic calling, parameter setting, fault alarms, data logging/export.Optional remote monitoring, MES interface, AI-based sand optimization—enables full data traceability and intelligent decision-making.Key FeaturesSuperior Sand Quality, Stable PerformanceEfficient mixing ensures uniform resin coating. Compressive strength ≥1.8 MPa, gas evolution ≤20 ml/g, fluidity ≥65 mm—reducing casting defects.Fully Automated, Intelligent & EfficientOne-button start; automatic sand feeding, metering, mixing, cooling, and conveying—supports unattended operation, reducing labor costs.Energy-Saving & Eco-FriendlyEnclosed design with pulse cartridge filter (emission ≤5 mg/m3), noise ≤80 dB(A)—environmentally compliant; heat recovery saves >20% energy.Modular Design, Easy MaintenanceIndependent modules; quick-change components (blades, screens, bearings)—long service life, short downtime.Safe & Reliable, Multi-Layer ProtectionFeatures emergency stop, overload protection, interlocked doors, temperature monitoring, explosion-proof motors (optional)—ensures stable operation in harsh conditions.Traceable Data, Smart Factory ReadyOptional batch management, energy monitoring, AI-based recipe optimization—enables full data traceability and digital transformation.Main Technical SpecificationsParameterParameterModel SeriesRS-2000 / RS-3000 / RS-5000 / RS-8000 CapacityExpandableResin SystemsFuran, Alkaline Phenolic, Silicate, PUMixing Time15–45 secondsMixing Homogeneity≥98%Metering AccuracyResin/Hardener: ±1%Control SystemOptional MES/remote monitoringTotal PowerDepending on configurationWeight6–50 tonsDimensionsCustomized by modelProtection RatingIP54/IP65 for critical partsTypical ApplicationsNo-bake sand production for large steel castings (wind turbine hubs, marine crankshafts, rolls)Resin sand molding for complex parts (pumps, valves, housings)Mass production of rail transit and construction machinery chassis componentsIntegrated with automated molding lines, central sand supply, and MES systemsCore equipment for foundry sand processing workshopsCompany ProfilePlease enter the title hereQingdao Dingli Machinery Co., Ltd. is a company specializing in the production of casting machinery equipment.
