A bag filling machine (or bagger) is an essential piece of industrial equipment designed to automate the process of accurately filling various bag types (like open-mouth, valve, or FIBC) with a precise, consistent weight of dry flowable materials such as powders, granules, grains, or cement, optimizing production speed and minimizing product giveaway. The machine’s core function involves a feeding mechanism (e.g., auger or gravity) controlled by a highly accurate electronic weighing system. The critical components of this system are the load cells, which are transducers that convert the mechanical weight of the material being dispensed into an electrical signal; common types used are S-Beam Load Cells for suspended weighing hoppers due to their high precision in tension and compression, or Shear Beam Load Cells in high-capacity platform setups. This signal is fed to an Electronic Weighing Controller/Indicator (often integrated with a PLC), which processes the reading, compares it to the target weight, and precisely controls the coarse and fine feed mechanisms to achieve high accuracy, typically around 0.1% of the full scale.
