Introduction
The KegLand Maltmuncher 3 Roller Grain Mill (Model KL03261) is specifically designed for home brewing enthusiasts to achieve an optimal crush for malted barley, wheat, and rye. Its three-roller design ensures an extra crush, providing a larger grain hopper capacity and the ability to double crush to precise specifications. This manual provides detailed instructions for assembly, operation, and maintenance to ensure safe and efficient use of your grain mill.
Included Components:
- Grain hopper
- Manual crank handle
- 12mm crank shaft
- Roller adjustment knobs
- Reinforced chassis with pre-aligned mounting holes
Safety Information
- Always ensure the grain mill is securely mounted to a stable surface before operation.
- Keep hands and loose clothing away from moving rollers during operation.
- Do not operate the mill with a drill at excessive speeds (recommended maximum 200 RPM) to prevent overheating the grain and damaging the mill.
- This unit is designed for Malted Barley, Wheat, and Rye. Misuse with other materials may cause damage and void any warranty.
- Always wear appropriate personal protective equipment, such as safety glasses, when operating machinery.
Assembly Instructions
- Attach the Hopper: Carefully place the grain hopper onto the main body of the mill, aligning the pre-drilled holes. Secure it using the provided screws and nuts.

- Mount the Mill: Position the mill on a sturdy surface, such as a wooden board, ensuring it is stable. Use the pre-aligned mounting holes on the reinforced chassis to secure the mill firmly. This prevents movement during operation.

- Adjust Roller Gap: The Maltmuncher features an adjustable third bottom roller for refined crushing. To adjust the gap, loosen the adjustment screws on the side of the mill and turn the adjustment knob to achieve your desired crush size. The knob often has markings (e.g., 0.032, 0.063) to guide your setting. Tighten the screws once the desired gap is set.

Operating Instructions
- Prepare for Milling: Place a suitable collection bucket or container directly underneath the mill's output chute to catch the crushed grain.
- Load Grain: Pour your malted barley, wheat, or rye into the grain hopper. The hopper has an approximate capacity of 5.5kg.

- Begin Milling:
- Manual Operation: Turn the manual crank handle steadily. The 12 TPI knurl on the rollers is designed to efficiently pull grain through while leaving the hull intact, which is crucial for forming an excellent filter bed during sparging.
- Drill Operation (Optional): If using a power drill, attach it to the 12mm crank shaft. Do not exceed 200 RPM. High speeds can generate excessive heat, potentially cooking or burning your grain and reducing the mill's performance. Use just enough power to keep the rollers turning smoothly and catching the grain.

- Monitor Output: Observe the crushed grain to ensure it meets your desired consistency. Adjust the roller gap as needed for finer or coarser grist.
Maintenance
- Cleaning: After each use, thoroughly clean the mill to remove any residual grain dust or particles. Use a brush or compressed air to clear the rollers and hopper. Ensure all parts are dry before storage to prevent corrosion.
- Inspection: Periodically inspect the rollers for wear or damage. Check that all screws and fasteners are tight.
- Storage: Store the grain mill in a dry, clean environment to prolong its lifespan.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Grain not crushing properly / inconsistent crush | Incorrect roller gap setting | Adjust the roller gap using the adjustment knobs until the desired crush is achieved. |
| Grain jamming in the rollers | Foreign object in grain; rollers too tight; excessive speed with drill | Inspect grain for foreign objects. Loosen roller gap slightly. If using a drill, reduce RPM to recommended 200 RPM. |
| Grain appears burnt or cooked | Excessive speed when using a power drill | Reduce the drill's RPM significantly. The recommended speed is around 200 RPM. |

User Tips
- For optimal crush and to prevent damage, always use a drill at a low speed, ideally around 200 RPM. Higher speeds can generate heat that negatively impacts your grain and the mill's performance.
- Experiment with different roller gap settings to find the perfect crush for your specific brewing needs and grain types. A good crush typically leaves the hull mostly intact while breaking the endosperm.
