ABSTRACT:
This invention, is an apparatus for grading pellets produced by a pelletizer from dry particulate batch material and a liquid, as for a melting furnace such as a glass furnace. The pellets are sensed by passing the pellets adjacent a graded passage. When a pellet reaches a graded passage matching its size, the pellet drops through the passage and at the same time actuates a sensor indicating a pellet of that respective size. The sensor is connected to a counting device which then can provide, through an appropriate control device, a count of over or undersized pellets or the pellet distribution. This information then can be appropriately used by the control device to control the amount of dry batch material or the amount of water introduced into the pelletizer and to maintain the pellets within a desired range.
