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.

Desafío

  1. High Accuracy: The system must be able to consistently deliver precise ingredient doses of materials varying in density, constitution, and at variable flow rates.
  2. Vibration and Impact Management: Load cells must maintain accuracy in a dynamic environment susceptible to disturbance caused by the mixing chamber or adjacent machinery.
  3. Compact Form Factor: Load cells must mount to the hopper above the blender without exceeding the pre-existing packaging constraints imposed by the machine.

Solución

  1. El sensor utiliza galgas extensométricas personalizadas de alta y baja temperatura, con compensación de temperatura añadida y pruebas de fatiga para garantizar la estabilidad de los datos.
  2. Incorpora materiales especializados sellados al vacío con excelente aislamiento eléctrico, estabilidad química, amplio rango de temperaturas y baja volatilidad. Los materiales elastómeros se someten a un pulido e inspección especiales, y se utilizan cables de vacío de calidad aeroespacial para que el sensor pueda funcionar en un entorno de vacío.
  3. Se emplea un sistema de sellado de tres capas, que incluye la protección de la galga extensométrica, dos capas de sellado de material al vacío y el sellado de la tapa. Esta protección multicapa evita eficazmente que la humedad afecte al rendimiento del sensor.

Conclusión

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.
