Efficient, adjustable grain roller that delivers consistent crushes with minimal kernel damage. Key benefits Precise control: Adjustable roller gap from 0 to 2.5 mm (set via screws) lets you dial in particle size for coarse or fine crushing while minimizing hull breakage. Higher throughput: 1.06 gal hopper reduces refills, so you process more grain in less time. Flexible operation: Use the included crank for manual grinding or attach a corded drill (not included) for faster, powered operation. Simple and reliable: Pour grain into the hopper and turn the handle — the crankshaft can be driven clockwise or counterclockwise without affecting the grind. Main features Adjustable roller gap (0–2.5 mm) for consistent, even crushing and controlled particle size. Hopper capacity: 1.06 gallons to improve workflow and reduce interruptions. Two grinding methods: manual crank for full control or powered operation with a corded drill (drill not included) for speed. User-friendly operation: easy filling and turning; reversible crankshaft direction works without changing settings. Performance and compatibility Delivers uniform grinding results that help reduce bran damage while producing the desired crush. Designed for straightforward attachment to a corded drill (drill sold separately) when higher throughput is required. No special setup needed beyond adjusting the screws to set the roller gap and securing the unit for operation. Practical applications Homebrewing: Grind malted barley to the right crush for efficient lautering and consistent mash performance. Baking and cooking: Prepare freshly crushed grains for cereals, porridges, or artisan flours with control over coarseness. Small-scale feed prep: Produce crushed grains for poultry or small livestock where consistent particle size improves mixing and intake. What you get and how to use Product includes the roller assembly with adjustable screws, hopper (1.06 gal), and a crank handle for manual operation. To use: set the roller gap with the screws, pour grains into the hopper, and turn the crank by hand or attach a corded drill (not included) to drive the shaft. Both clockwise and counterclockwise rotation are supported without affecting the grind. Reliable, easy to adjust, and suitable for both manual and powered use — ideal when you need consistent grain crushing with simple, fast operation.
