Product Introduction: Planetary Variable-Frequency Rotor Sand Mixer

The planetary rotor sand mixer is a high-performance, versatile mixing system designed for sand preparation in foundry applications, including the production of sand molds and cores. It is widely applicable to casting processes for materials such as cast iron, steel castings, and aluminum alloys.

Particularly suited for manufacturing high-precision, high-strength sand molds, its defining innovation is the integration of planetary motion mechanics and variable-frequency drive technology.

This combination enables precise control over mixing intensity and speed, ensuring thorough homogenization of sand, binders, and additives.

The result is superior mold quality with minimized defects, optimized production efficiency, and reduced material waste.

Advantages Of Planetary Rotor Sand Mixer

CO-NELE CMPS Planetary Variable Frequency Rotor Sand Mixer – The most advanced, fastest, and most efficient batch-type sand mixer for foundry applications.

High-Efficiency Mixing:
High-intensity mixing ensures uniform coating of all sand grains, maximizes bonding strength, and reduces costs associated with excessive bentonite and additives. The sand mixture remains homogeneous and consistently high-quality.

High-Speed Rotor-Type Sand Mixer

Planetary Rotor Sand Mixer Mixing Technology

CO-NELE CMPS Planetary Variable Frequency Rotor Sand Mixer – Ensures rapid and precise preparation of sand mixtures within shorter cycle times.

Dead-Zone-Free Design and Homogeneity:
The obstruction-free mixing chamber allows the rotor to rotate within its designated area. Equipped with dual motion (rotation and revolution) and high-speed rotor blades, the system eliminates mixing dead zones commonly found in traditional mixers. The resulting sand mixture is uniform, loose, and features an excellent texture, ensuring consistent quality without uneven blending.
