Gravimetric Blender Weighing
Load Cell for Gravimetric Mixture Blender
Gravimetric blenders play a crucial role in industries where precisely monitoring the mixture quantities is required, such as in plastics manufacturing or medicinal processing. Being able to accurately meter raw materials such as fine or coarse powders, resin, regrinds, colouring agents, and other additives ensures efficiency and consistency in the output product. The stringent accuracy requirements demand a load cell that excels in off-centre loading and precision weighing of hopper content.
Défi
- High Accuracy: The system must be able to consistently deliver precise ingredient doses of materials varying in density, constitution, and at variable flow rates.
- Vibration and Impact Management: Load cells must maintain accuracy in a dynamic environment susceptible to disturbance caused by the mixing chamber or adjacent machinery.
- Compact Form Factor: Load cells must mount to the hopper above the blender without exceeding the pre-existing packaging constraints imposed by the machine.
Solution
- Le capteur utilise des jauges de contrainte haute et basse température personnalisées, avec une compensation de température supplémentaire et des tests de fatigue pour garantir la stabilité des données.
- Il intègre des matériaux spécialisés scellés sous vide qui présentent une excellente isolation électrique, une stabilité chimique, une large gamme de températures et une faible volatilité. Les matériaux élastomères subissent un polissage et une inspection spéciaux, et des câbles sous vide de qualité aérospatiale sont utilisés pour permettre au capteur de fonctionner dans un environnement sous vide.
- Un système de scellement à trois couches est utilisé, comprenant la protection de la jauge de contrainte, deux couches de scellement du matériau sous vide et le scellement du capuchon. Cette protection multicouche empêche efficacement l'humidité d'affecter les performances du capteur.
Conclusion
By integrating ANYLOAD’s single-point load cells into the gravimetric blender, the system delivers ±0.03% weighing accuracy for precise material blending and improved production efficiency. Its compact, space-saving design fits a wide range of hopper configurations while handling eccentric loads with reliable performance. Constructed from high-strength aluminum alloy, the load cell offers excellent durability, vibration resistance, and cost efficiency. The single-point design also simplifies installation by eliminating the need for junction boxes, while its optimized structure provides enhanced torsion resistance for long-term stability and accurate weighing.
