The Weighfeeder is an industrial device used to convey and simultaneously measure the mass flow rate of bulk, granular, and coarse materials in production lines, typically installed beneath silos or storage hoppers to provide controlled feeding to downstream equipment. A flanged inlet hopper at the top of the housing for receiving material, an internal conveyor belt a gearbox motor at the end of the unit, and a weighing section equipped with a load cell along the conveying path to continuously measure the weight of material passing through.

Operation is based on the combination of mechanical material conveying and continuous in-motion weighing: after entering through the top hopper, material is carried on the conveyor belt , and as it passes through the weighing section, its weight is measured by the load cell. The control system combines the instantaneous weight data with the belt speed to calculate the actual mass flow rate, adjusting the drive motor speed as needed to achieve the desired discharge rate. Due to its ability to simultaneously convey and accurately weigh material at high capacities, this type of feeder is widely used in industries such as cement, mining, steel, and mineral processing for the precise feeding of raw materials to mills, kilns, and process lines.
