What is another term for gravity grain bin?

• A. Grinder
• B. Sorter
• C. Sifter
• D. Sluice box

Answer: (C)

When you’re thinking about a device that uses gravity to separate material by size, the best term is a sifter. A sifter is a screen or mesh that lets smaller particles pass through while larger ones stay on top, and gravity helps pull the material through the openings. This matches a gravity-based grain bin’s function of sorting by size. A grinder would reduce particle size by crushing, not separate by screening. A sorter is a broad term for devices that classify by some attribute, not necessarily by passing through a screen. A sluice box uses flowing water to separate by density, not simply by size through a screen. So, the sifter is the correct term.
