Quick Answer
A grain mill may jam during use due to clogged or stuck grain, misaligned millstones, or worn-out gear teeth. This can cause the mill to malfunction, leading to a buildup of pressure and potentially causing damage to the mill's internal components. Regular maintenance can help prevent such issues.
Causes of Jamming
Grain mill jamming is often caused by clogged or stuck grain, which can accumulate in the mill’s internal mechanisms and prevent the millstones from rotating freely. To prevent this, it’s essential to regularly clean the mill and ensure that the grain is flowing smoothly through the system. A clogged grain mill can lead to increased pressure and wear on the mill’s components, potentially causing damage and reducing its lifespan.
Maintenance Techniques
To maintain your grain mill and prevent jamming, it’s recommended to clean the mill after each use. Simply disassemble the mill and remove any stuck grain or debris using a soft-bristled brush or a small vacuum cleaner. You can also oil the gear teeth and millstones to reduce friction and wear. For example, apply a few drops of food-grade oil, such as canola or coconut oil, to the gear teeth and millstones, and then use a clean cloth to wipe away any excess oil.
Troubleshooting
If your grain mill does jam during use, don’t force it to continue operating, as this can cause further damage. Instead, stop the mill and carefully disassemble it to identify the source of the problem. Check for any clogged grain or debris, and clean the mill as described above. If the issue persists, you may need to adjust the millstones or replace worn-out gear teeth. Consult your grain mill’s user manual or contact the manufacturer for guidance on how to perform these tasks.
