As a core equipment in the foundry industry, the CO-NELE Planetary Rotor Sand Mixer is designed to solve the pain points of traditional sand mixers such as uneven mixing, dead corners, low efficiency and high energy consumption. This professional CO-NELE foundry sand mixer integrates planetary revolution and high-speed rotation technology to realize three-dimensional homogeneous mixing of molding sand, binders, additives and other materials, ensuring stable and reliable sand quality for high-precision casting production. Widely used in iron casting, steel casting, aluminum alloy casting, auto parts, engineering machinery and precision casting fields, the CO-NELE Planetary Rotor Sand Mixer is an essential supporting equipment for automatic casting production lines, and it is also a high-efficiency and energy-saving alternative to traditional mixing equipment.
Working Principle
The CO-NELE Planetary Rotor Sand Mixer adopts a dual-motion coupling mechanism of revolution + rotation, which fundamentally eliminates mixing dead zones and ensures that every particle of material is fully stirred and coated. As a high-quality Planetary Rotor Sand Mixer for foundry, this equipment’s mixing arm drives 3-4 rotors to revolve around the main shaft at a low speed (20-45 r/min), which drives the overall circulation of materials in the mixing cylinder; at the same time, each rotor rotates at a high speed (240 r/min) independently, generating strong shearing, impact and dispersion effects on the materials. Under the combined action of revolution and rotation, the molding sand and additives in the cylinder tumble, shear and wrap fully in three dimensions, so that bentonite, coal powder and other auxiliary materials can evenly coat the sand particles, and the consistency of sand strength, moisture content and air permeability reaches a high level, laying a solid foundation for reducing casting defects.
Core Structure & Technical Features
1. Core Structure
- Mixing Cylinder: Equipped with wear-resistant lining plate, which effectively prevents sand particle wear, reduces equipment loss, and is easy to clean and maintain, ensuring long-term stable operation of the CO-NELE Planetary Rotor Sand Mixer
- Planetary Rotor System: 3-4 sets of high-speed rotors and low-speed mixing arms are configured, driven by frequency conversion, which can adjust the speed according to the material characteristics and mixing requirements to achieve optimal mixing effect for the CO-NELE foundry sand mixer.
- Precise Batching Unit: Equipped with electronic weighing hoppers for raw sand and auxiliary materials, with pneumatic precise feeding function, which ensures accurate proportion of each component and further improves the stability of sand quality.
- Drive & Control System: Adopts dual motors (for high-speed rotors and low-speed revolution) and frequency conversion system, matched with PLC automatic control, which can realize automatic operation such as feeding, mixing, discharging and cleaning, reduce manual intervention and improve production efficiency.
- Discharging Mechanism: Hydraulic quick-opening door design, which realizes fast and thorough discharging without material residue, shortens the production cycle and improves production continuity.
2. Key Technical Advantages
High Mixing Uniformity, No Dead Zones The unique planetary motion trajectory of the CO-NELE Planetary Rotor Sand Mixer ensures that there is no mixing dead zone in the cylinder, and the sand and additives are mixed homogeneously. The fluctuation of compaction rate, air permeability and strength of the mixed molding sand is extremely small, which can significantly reduce casting defects such as air holes and sand holes, making it a reliable high efficiency sand mixer for foundries.
Short Mixing Cycle, High Efficiency & Energy Saving As an energy saving sand mixer, the CO-NELE Planetary Rotor Sand Mixer has a mixing cycle of only 2-3 minutes per batch, which is 30%-50% more efficient than traditional sand mixers; the frequency conversion speed regulation function can output power on demand according to the production load, reducing energy consumption by more than 20%, and realizing energy saving and emission reduction while improving efficiency.
Stable Sand Quality, Good Consistency The deviation of strength, moisture content and air permeability of each batch of mixed sand is small, which is perfectly compatible with automatic molding lines, effectively reducing the casting rejection rate and ensuring the stability of product quality.
Wear-Resistant & Durable, Easy Maintenance Key components such as rotors and lining plates are made of high-wear-resistant alloy materials, which have a long service life; the modular design makes disassembly, assembly, cleaning and replacement of parts more convenient, reducing maintenance costs and downtime.
Green & Environmental Protection, Low Dust The fully sealed structure is matched with a dust removal interface, which effectively reduces dust overflow and meets the environmental protection emission standards; the automatic batching system reduces material waste and realizes green production.
