During the fill cycle, the downstream feeder is operated in a volumetric mode (i.e., at a constant speed). The feeder then operates in gravimetric mode (i.e., its speed is controlled by measuring the loss in weight of material inside the hopper) after the downstream hopper has been filled. A schematic of a gravimetric feeder is given in …
Gravimetric Coal Feeder is a belt conveyor which measures the amount of coal, in terms of weight, being conveyed / fed to the pulveriser. The feed rate is computed from load cell signal and belt speed signal collected from the load cells strategically mounted below the belt and the hollow shaft sensor mounted on the tail pulley of the belt conveyor in the …
