Abstract
A method and apparatus transfer a material from first roller within a container to at least one second roller, and transfer the material from the second roller to at least one third roller. The second roller and the third roller form a loading nip at a location where the second roller is closest to the third roller. The method and apparatus transfer the material from the third roller to at least one recipient device, and measure current flow between the second roller and the third roller using a measurement device. Then, the method alters the relative rotation rate difference between the first roller and the second roller based on the current flow to maintain a predetermined density of the material at the loading nip using a controller.
