Equipment application field
Double screw gravimetric feeders, also known as screw loss-in-weight feeders, are an essential tool for a variety of industries, including plastic, rubber, chemical, food, and pharmaceuticals. These feeders are designed to accurately measure and dispense a variety of powders and granules with a high degree of precision and consistency.
One of the primary benefits of gravimetric feeders is their ability to control the flow rate of materials with great accuracy. This, in turn, helps to minimize waste, reduce downtime, and increase productivity. Additionally, gravimetric feeders are highly versatile and can be used to feed a wide range of materials, including powders, flakes, granules, and pellets.
