【Improvement Case】 By replacing the supply device with a circle feeder in equipment facing issues such as bridging, we can solve supply challenges. There is a cost advantage as the existing hopper can be reused. Additionally, the introduction of the circle feeder can improve the segregation of raw materials in the storage tank, thereby reducing quality deterioration in the next process.
