Product DescriptionProduct DescriptionProduct Description of S25 Series Twin-Arm Continuous Sand MixerThe S25 Series Twin-Arm Continuous Sand Mixer is a high-performance, fully automatic resin sand mixing machine designed for modern, high-efficiency foundry production. It is suitable for preparing molding sand for furan-coated sand, hot-box, and cold-box processes. With a twin-mixing-arm alternating operation and continuous sand discharge design, it ensures uniform mixing, stable sand output, and outstanding efficiency. It is widely used in core and mold production for high-precision castings in automotive, engine, valve, pump, and aerospace industries.Integrating sand conveying, resin dosing, hardener metering, high-speed mixing, automatic chamber cleaning, and PLC intelligent control, this machine enables fully automatic and continuous operation from raw materials to mixed sand—making it a core component of intelligent and green foundry production lines.Working PrincipleThe S25 Series operates on a twin-mixing-chamber alternating cycle:Arm #1 in Operation: Base sand, resin, and hardener are fed into the first mixing chamber in precise ratios and thoroughly mixed by high-speed rotating blades. The mixed sand is continuously discharged to the core shooter.Arm #2 in Preparation: While Arm #1 is operating, Arm #2 completes chamber cleaning and material metering, ready for immediate use.Automatic Switching: When Arm #1 finishes its discharge cycle, the system automatically switches to Arm #2. Arm #1 then enters cleaning and preparation mode—ensuring seamless continuous sand output.Key FeaturesTwin-Arm Alternating, Continuous DischargeUnique dual-chamber design enables seamless "operation-preparation" switching, with sand output up to 8–25 tons/hour, meeting continuous sand supply for large-scale production lines.Uniform Mixing, Stable QualityHigh-speed twin-rotor counter-flow agitation provides strong shearing force, short mixing time (≤15 sec), high resin coating efficiency, excellent sand flowability, and consistent core strength.Precise Metering, Intelligent ControlResin and hardener are dosed via high-precision gear pumps + mass flow meters with closed-loop control, achieving ±1% accuracy. Supports recipe storage, automatic recall, and remote monitoring.Automatic Chamber Cleaning, Anti-CuringBefore each switch, the mixing chamber is automatically sprayed with cleaning fluid (e.g., release agent or dedicated cleaner) to remove residual resin and prevent curing blockage—ensuring long-term reliability.Modular Design, Easy MaintenanceWear-prone parts (arms, blades, liners) made of wear-resistant alloy for long life and easy replacement. Rational layout with ample maintenance space reduces downtime and costs.Fully Enclosed, Eco-SafeFully enclosed operation with dust extraction ports effectively controls dust and VOC emissions—compliant with GB, EU, OSHA, and other occupational health and environmental standards.Main Technical SpecificationsParameterSpecificationModelS255/S258/S2510/S2515/S2520/S2530 Classified by output capacityOutput Capacity3-30tons/hourMixing Time≤15 secondsResin Accuracy±1%Hardener Accuracy±1%Control SystemPLC + HMI + SCADA (optional)Recipe Storage≥20 setsTotal Motor Power35kw-75kw Depending on modelAir Requirement0.6 MPa, 1.5 m3/minWeight4,500 ~ 8,000 kgSuitable SandsFuran-coated, hot-box, cold-box, sodium silicate sands, etc.Typical ApplicationsContinuous production of engine blocks, heads, and intake manifoldsAutomated core making lines for large valves, pumps, and impellersMass production of resin sand cores for rail and wind power castingsCore mixing equipment for new smart foundriesRetrofit projects for replacing old batch mixersQingdao Dingli Machinery Co., Ltd.Qingdao Dingli Machinery Co., Ltd. is a company specializing in the production of casting machinery.
