A new 3-in-1 system combines a Vibroscreen vibratory screener, a batch hopper, and an integral feed control device that regulates the flow of material into the screener. The system is intended for applications that require screening in batches. The feed control device consists of a circular disc positioned below the flexible connector at the screener’s inlet, perpendicular to the flow of material. The diameter of the disc is smaller than the inside diameter of the inlet, forming an annular gap through which material can pass. Because the disc vibrates with the screener lid to which it is affixed, the flow of material through the gap remains uniform. Interchangeable discs in a range of diameters are provided to achieve various feed rates.
