VEVOR Manual Grain Mill, Homebrew Malt Grinder, Adjustable Barley Mill Crusher for Wheat Beer Brewing - with 2 Stainless Steel Rollers, 1.06 Gallon Hopper & Metal Base Plate

The rollers are specially optimized for malt, barley and grain brewing, with soft alloy surface that will get scratched and worn quickly by hard corn kernels. Corn also produces too much fine powder which easily clogs the gap adjustment mechanism and damages the gear system long-term.
