Feedersand

Feedersand is a term that does not have a single, widely accepted definition in technical literature. In practice, it is rarely used as a standalone concept and may reflect a misspelling or compound form of more common terms such as "feeder sand" or "sand feeder," depending on the field. As a result, its meaning varies by context and is not standardized.

In foundry and metal casting, a feeder refers to a channel that supplies liquid metal to a casting as it solidifies; the sand surrounding the feeder forms part of the mold. Some informal usages may refer to the sand used in constructing such feeders as "feeder sand," but this is not a standard designation.

In bulk material handling or process engineering, a feeder is a device that introduces material into a system; if the term appears with sand, it may indicate the sand fraction handled by that feeder. This usage likewise lacks established terminology.

In hobbyist contexts, such as aquarium or terrarium substrates, "feedersand" could be used informally to describe sand used as a substrate that supports feeding organisms, but again this is not a formal term.

Because there is no established definition, readers should seek contextual clues—such as the document’s industry, region, or cited sources—to interpret the term. If possible, consult the original source or request clarification from the author. See also Feeder; Sand; Foundry sand; Sand casting.
