High-Quality Resin Sand Mixer for Foundry Use

The Resin Sand Mixer is a core equipment in chemically bonded sand molding and core-making processes, specifically designed for the continuous or batch mixing of furan resin sand, alkaline phenolic sand, sodium silicate sand, and other no-bake sand systems. Utilizing high-speed powerful agitation + precise metering + fully automatic control, the mixer ensures thorough blending of base sand, resin, hardener, and additives within seconds—producing stable, highly flowable, high-strength molding or core sand that meets the demanding quality requirements of large, complex, and precision castings.

This mixer is suitable for standalone operation or integration into automated sand lines, widely used in the production of large steel and iron castings for wind power, shipbuilding, metallurgy, heavy machinery, construction equipment, valves, and rail transit. Available in continuous and batch modes, with a capacity range of 1–30 tons/hour, it can be flexibly configured based on customer process requirements.

1. Precise Metering System
Equipped with high-precision load cells and frequency-controlled screw feeders for real-time dynamic measurement of base sand (accuracy ±0.5%).
Resin and hardener are dosed by corrosion-resistant metering pumps (e.g., gear or screw pumps) at preset ratios, with flow control accuracy ±1%.

Uniform Mixing, Stable Performance
High-speed agitation ensures complete resin-sand blending—high strength, low gas emission, excellent flowability—reducing blowholes and veining.

Precise Metering, Controlled Ratios
Fully automatic proportioning of sand, resin, and hardener with minimal error—ensuring consistent sand properties.

High Automation, Easy Operation
One-button start; automatic metering, mixing, and discharge. User-friendly interface—minimal training required.

Robust Structure, Easy Maintenance
Heavy-duty frame resists vibration; quick-change components (bearings, seals, blades)—easy inspection, low maintenance cost.

Compatible with Multiple Resin Systems
Supports furan, alkaline phenolic, modified silicate, PU resins—process changeover via recipe switch.

Safe & Reliable, Comprehensive Protection
Features emergency stop, overload protection, interlocked doors, temperature monitoring—ensures stable operation in harsh environments.

No-bake sand mixing 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 components

Integrated with continuous sand lines, automated molding lines, and central control systems

Small-batch high-performance sand preparation for labs or pilot plants
