A system and mechanism for bottom ash flow turndown from a hopper, through a crusher, and to a conveyor, the system including a fixed flow restrictor and a variable speed side discharge crusher to modulate bottom ash flow in the absence of gate or valve flow from a hopper, the conveyor providing a signal corresponding to an overfeed condition to enable a controller to operate the crusher and/or the conveyor to eliminate overfeed conditions.

A rotary impact separator is provided for separating a material. The rotary impact separator includes a body portion comprising one or more walls. The one or more walls define a substantially hollow chamber, an inlet opening, a first outlet opening, and a second outlet opening. The rotary impact separator includes an impact device extending at least partially into the hollow chamber. The impact device includes a shaft that extends within the hollow chamber. The shaft rotates within the hollow chamber. One or more blades are attached to the shaft and contact the material. A diverter is attached to an interior surface of one of the one or more walls. The diverter extends along the shaft and projects from the interior surface toward the shaft. Methods for recovering two or more co-products from a material are provided.
