Metering mechanism for strand-type bulk solid materials
Abstract:
A system and method are disclosed that provide a specific volumetric output (e.g., product feed and discharge) of a material. In some implementations, these systems and methods are particularly suited for use with strand-type materials, namely, materials having difficult handling characteristics. For some implementations, a specific pile depth and width of a material is created on a moving belt to provide a specific volumetric output based on the speed of the belt. One or more leveling drums can be used to make the pile depth consistent. Moreover, a weighing system can be provided that is used in combination with the metering mechanism and other components (e.g., a control system) to create a “weight-loss” type weigh feeder.
