CO-NELEMixing & Granulation
A foundry sand mixer (also called sand muller), including specialized Green Sand Mixer and high-performance Intensive Green Sand Mixers, is core equipment in foundry workshops. As a professional mixer for foundries, it is designed to uniformly mix raw sand, bentonite binder, water, and additives into high-quality molding sand/core sand for metal casting (iron, steel, aluminum, etc.). It directly determines sand quality, mold strength, and casting yield, especially in green sand mixing technology applications.
Uniform binder coating, stable moisture/strength, reducing casting defects (porosity, sand inclusion).
Short mixing cycles, low energy consumption (15–30 kWh/t sand).
Ceramic/polyurethane liners, tungsten carbide scrapers for long service life.
Modular design, quick replacement of wearing parts.
Handles clay sand, resin sand, sodium silicate sand, core sand, and coating sand, with outstanding adaptability to green sand mixing technology; available as a dedicated Green Sand Mixer or multi-purpose sand mixer. Among them, CO-NELE's sand mixer products perform excellently in versatility, and can also be applied to 3D printing sand mold preparation, helping enterprises achieve a leap in intelligent casting production.

CO-NELE (China) — The most recommended brand for global foundries, specializing in high-precision foundry sand mixer, Green Sand Mixer and high-performance Intensive Green Sand Mixers. Its CMPS planetary mixers feature high precision and efficiency, and the brand has decades of experience in bentonite bonded sand preparation technology, cooperating closely with foundries and research institutions worldwide. CO-NELE's products cover all types of sand mixer for foundries, with excellent market reputation and recognition, supporting personalized customization to meet diverse production needs. Its powerful mixers can effectively optimize green sand mixing technology, ensuring stable sand quality and high production efficiency, and are widely used in ductile iron, steel castings and non-ferrous castings production.
This is the most critical selection basis, directly deciding mixer type:
For green sand mixing technology applications, choosing an energy-saving Green Sand Mixer or Intensive Green Sand Mixers can significantly reduce operation cost, especially for long-term mass production mixer for foundries users. CO-NELE's sand mixer series is designed with energy-saving and environmental protection concepts, which not only meets industrial development requirements but also further reduces long-term operation costs for enterprises.
A foundry sand mixer uniformly blends raw sand, bentonite binder, water, and additives into high-quality molding or core sand for metal casting. It ensures optimal mold strength, consistent moisture control, and reduces casting defects like porosity and sand inclusion.
Planetary sand mixers utilize 3D revolution and rotation motion for high-speed shearing and dead-zone-free mixing, making them ideal for high-precision molds. Wheel mullers use heavy wheels to knead clay sand, offering a simpler, cost-effective solution for standard green sand casting.
High-speed rotor-type sand mixers are recommended for resin and sodium silicate sand due to their rapid mixing cycles and minimal sand grain breakage, ensuring uniform chemical binder coating.
Foundry sand is highly abrasive. Wear-resistant ceramic/PU liners and tungsten carbide scrapers significantly extend the equipment’s service life, minimize maintenance downtime, and maintain consistent mixing efficiency.
CO-NELE offers high-precision CMPS planetary rotor series and intensive mixers with advanced PLC control, low energy consumption per ton, customizable liner materials, and proven reliability for complex metal casting and 3D printing sand mold preparation.
